---|---
DANGER
| Danger of death from explosion
– Explosion hazard due to high-charging processes in connection with free- hanging probe with cable FEP
– Fixed installation of the FEP cable!
**DANGER| Danger of death from explosion**
– The probe must be installed in such a way that rubbing or impact of the sensor head (sensor element), e. g. against a tank wall, is prevented. It is also important to consider the operating conditions such as flow conditions!
- NOTE – The technical data listed in the EU-type examination certificate are binding. Download this by accessing www.bdsensors.de or request it by e-mail or phone: info@bdsensors.de | phone: +49 (0) 92 35 98 11 0
- NOTE – Make sure that the entire interconnection of intrinsically safe components remains intrinsically safe. The owner-operator is responsible for the intrinsic safety of the overall system (entire circuitry).
- NOTE – If there is an increased risk of damage to the device by lightning strike or overvoltage, increased lightning protection must additionally be provided!
- NOTE – Do not remove the packaging or protective caps of the device until shortly before the mounting procedure, in order to exclude any damage to the diaphragm and the threads! Protective caps must be kept! Dispose of the packaging properly!
- NOTE – Treat any unprotected diaphragm with utmost care; this can be damaged very easily.
Mounting steps for probes
- The mounting accessory is available (as standard, the probe is supplied without fastening material; mounting clamps, terminal clamps and mounting flanges are available as accessories from BD|SENSORS)
Fasten the probe properly according to your requirements.
- NOTE – Always immerse the device slowly into the fluid to be measured! If the probe strikes the liquid surface, the diaphragm could be damaged or destroyed.
- NOTE – Free-hanging probes with FEP cables may not be used if effects of highly charging processes can be expected.
Mounting steps for flange version (LMK 382 / LMK 382H)
- The mounting thread is clean and undamaged
- The O-ring is undamaged and seated in the designated groove at the probe end
- Screw the mounting thread of the probe into the probe flange by hand
- Tighten the device using an open-end wrench. (approx. 25 Nm)
- Mount the flange according to your requirements.
If you need a new probe flange, this can be ordered from BD|SENSORS as an accessory.
Removal of protective cap (if necessary)
For the protection of the diaphragm, some of the probes have a plugged-on
protection cap. If the device shall be used in highviscosity media such as
sludge, a removal of the cap before start-up is necessary. Thus, the sensor
becomes flush and the medium will attain quickly to the diaphragm.
Removal by hand
- Hold the probe in a way that the protection cap points upwards.
- Hold the probe with one hand on the sensor section (1).
- Remove the protection cap (2) with the other hand.
Removal with a tool (recommended)
- Hold the probe in a way that the protection cap points upwards.
- Slide a small tool such as a screwdriver (8) straight through two opposite drill holes in the protective cap (2).
- Lever it off by moving up the handle of the screwdriver.
NOTE – Make sure that the sensor (7) under the protection cap will not be damaged!
Cable protection (optional)
According to order, the probe was supplied with cable protection; if the probe
was prepared for mounting by means of a stainless steel or plastic tube
(optional), the customer must affix a cable protection themselves.

- The cable must be installed fightlly
- Do not clean the device and, if applicable, the connection cable, in a dry state! Use a moist cloth, for example
The following warning sign is affixed on devices with plastic components.
NOTE – The warning sign must not be removed from the device!
Overvoltage protection
If the probe is used as electrical equipment of category 1 G, then a suitable
overvoltage protection device must be connected in series (attend the valid
regulations for operating safety as well as EN60079-14).
Schematic circuit design
The operation of an intrinsically safe probe in intrinsic safe areas requires
special care when selecting the necessary Zener barrier or transmitter
repeater devices to allow the utilization of the device’s properties to the
full extent. The following diagram shows a typical arrangement of power
supply, Zener barrier and probe.
NOTE
Additionally, observe item (17) of the EU-type examination certificate which
specifies special conditions for intrinsically safe operation.
Exemplary circuit description
The supply voltage of e.g. 24 VDC provided by the power supply is led across
the Zener barrier. The Zener barrier contains a series of resistances and
breakdown diodes as protective components. Subsequently, the operating voltage
is applied to the device and, depending on the pressure, a particular signal
current flows.
Danger of death from explosion
- Operation of intrinsically safe devices as zone-0 equipment only with ungrounded and galvanically isolated power supply.
Selection criteria for Zener barriers and galvanic power supply
The minimum supply voltage VS min of the device must not fall short since a
correct function of the device can otherwise not be guaranteed. The minimum
supply voltage has been defined in the respective product-specific data sheet
under “Output signal/supply”.
When using a galvanically insulated amplifier with linear bonding, note that the terminal voltage of the probe will decrease like it does with a Zener barrier. Furthermore, you have to note that the supply will additionally decrease with an optionally used signal amplifier.
Test criteria for the selection of the Zener barrier
In order not to fall below VS min, it is important to verify which minimum
supply voltage is available at full level control of the probe. The full level
control, i.e. a maximum or nominal output signal (20 mA), can be reached by
applying the maximum physical input signal (pressure).
The technical data of the barrier will usually provide the information needed for the selection of the Zener barrier. However, the value can also be calculated. If a maximum signal current of 0.02 A is assumed, then – according to Ohm’s law – a particular voltage drop will result from the series resistance of the Zener barrier. This voltage drop is subtracted by the voltage of the power supply and as a result, the terminal voltage is obtained which is applied on the probe at full level control. If this voltage is smaller than the minimum supply voltage, another barrier or a higher supply voltage should be chosen.
NOTE
When selecting the ballasts, the maximum operating conditions according to the
EU-type examination certificate must be observed. When assessing these, refer
to their current data sheets to ensure that the entire interconnection of
intrinsically safe components remains intrinsically safe.
NOTE
For devices with HART communication (H-devices) When selecting the barrier or
power supply, you must look out for any ballasts which are not suitable for
HART communication. Most manufacturers offer a device group specially
developed for this application.
Calculation example for the selection of the Zener barrier
The nominal voltage of the power supply in front of the Zener barrier is 24
VDC ± 5 %. This results in:
-
maximum supply voltage:
VSup max = 24 V * 1.05 = 25.2 V -
minimum supply voltage:
VSup min = 24 V * 0.95 = 22.8 V
The series resistance of the Zener barrier is listed with 295 ohm.
The following values must still be calculated:
-
voltage drop at the barrier (with full conduction):
Vab barrier = 295 * 0.02 A = 5.9 V -
terminal voltage at the device with Zener barrier:
VKl = VS up min – Vab Barriere = 22.8 V – 5.9 V = 16.9 V -
minimum supply voltage of the device (according to datasheet):
VKl min = 12 VDC (corresponding to VS min)
Condition:
VKl ≥ VKl min
Result:
The terminal voltage of the device with a Zener barrier lies at 16.9 V and is
therefore higher than the minimum supply voltage of the device which lies at
12 VDC. This means the Zener barrier has been selected correctly regarding the
supply voltage.
NOTE
Note that no line resistances have been listed in this calculation. However,
these will lead to an additional voltage drop that must be taken into account.
Electrical installation
Connect the device electrically according to the information specified on the
manufacturing label, the following table, and the connection circuit diagram.

-
NOTE – For a clear identification, the intrinsically safe cables are marked with light blue shrink tubing (over the cable insulation). If the cable has to be modified (e. g. shortened) and the marking at the cable end has been lost in the process, it must be restored (for example, by marking it again with light blue shrink tubing or an appropriate identification sign).
-
NOTE – With shielded cables, the cable shield must be connected to earth potential. Use the appropriate grounding clamps for this. Pay attention to a low-impedance connection. Avoid potential differences (earth potential) between measuring and connection points, because this can lead to a defect in the probe. To avoid this, use a suitable connection technology or suitable equipotential bonding.
-
NOTE – In the case of relative pressure gauges, the cable contains a ventilation tube for pressure equalization. Route the end of the cable into an area or suitable connection box which is as dry as possible and free from aggressive gases, in order to prevent any damage.
-
NOTE – Usually, the required cable is included in the scope of delivery. If it is although necessary to connect an existing or special cable, the total resistance will increase. For applications, where this additional resistance of the connecting cable could cause problems, this cable has to be checked with the following calculation.
-
RL: resistance of connecting cable in Ω
-
ρ: specific resistance in Ω mm²/m
-
l: cable length in m
-
A: cross-section of a conductor in mm²
-
Vtot: total voltage drop
-
Rload: load resistance (to be taken out of the current datasheet)
following condition has to be fulfilled:
- VS: planned supply voltage
- VS min: minimal supply voltage (to be taken out of the current datasheet)
Specific features
HART communication (for H-Devices)
Danger of death from explosion
The intrinsically safe circuit for connecting a HART communications interface
(HART communicator or HART modem) may be broken only if there is no risk of an
explosion.
The analogue output signal is overridden by an additional signal according to the HART specification. The device can be configured via a HART-communication device. Therefore, we suggest our programming kit CIS-G (available as an accessory). It consists of HART modem, connecting cables as well as configuration software and allows a simple and time-saving configuration of all parameters. (The software is compatible with all Windows systems from Windows 98 and higher.)
for trouble-free operation, the following requirements are fulfilled:
maximal cable length between device and power supply:
- Lmax: maximum length of cable in [m]
- RV: resistance of the cable together with the load resistance in [Ω]
- CV: capacity of the cable in [pF/m]
resistance R:
- U: power supply in [VDC]
The resistance must be at least 240Ω.
Detachable probes
Danger of death from explosion
Only separate the sensor head from the cable part when no explosion hazard
exists.
In order to facilitate stock keeping and maintenance, the sensor head is plugged to the cable assembly with a connector and can be easily changed. The following probes are detachable: LMK 358, LMK 358H, LMP 308 and LMP 308i.
Disassembly
- Hold the probe on the sensor section (2) with one hand and turn the nut (4) carefully to the left with the other hand. Prevent torsion of the cable section (3) against the housing!
- While screwing and pulling off the sensor section (2) from the cable section (3), hold it straight to prevent damages on the plugs.
Assembly
- O-rings are not damaged (5, 6) or damaged O-rings have been replaced
- Radial O-rings (5) have been greased with Vaseline or O-ring grease
- Any grease residues have been removed from the axial O-ring (6).
- Plug the cable section (3) straight into the plug of the sensor section (2).
- Hold the probe onto the sensor section (2) with one hand. Screw on and tighten the nut (4) carefully with the other hand. Prevent torsion of the cable section (3) against the housing!

Commissioning
Danger of death from explosion
- Explosion hazard if the operating voltage is too high (max. 28 VDC)!
- Operate the device only within the specification! (according to data sheet)
- The device has been installed properly
- The device does not have any visible defect
- The device is operated within the specification. (see data sheet and EU-type examination certificate)
In case of highly precise devices with an accuracy of 0.1 % FSO, a microcontroller-controlled electronic system is used for signal processing. This electronic system is used for signal improvement. Due to the principle, the processing of measured values requires a longer time than with purely analogue sensors, which only comprise amplification circuitry. Due to the longer processing time, the output signal follows the measured value not continuously but in jumps. In case of relatively stable and slowly changing measured values, this property plays a minor role. Compare this with the information on the adjusting time in the datasheet.
In the case of i-devices with optional communication, interfaces can also be configured by these electronics. Offset, span and damping are programmable within the limits given in the data sheet. For configuring the device, the programming kit CIS-G consisting of Adapt 1, Windows compatible programming software P-Scale 510, power supply and connecting cable is necessary. This can be ordered additionally from BD|SENSORS.
