DANGER
Danger of death from improper installation
- Installation must be performed only by appropriately qualified persons who have read and understood the operating manual.
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 – If there is increased risk of damage to the device by lightning
strike or overvoltage, increased lightning protection must additionally be
provided!
NOTE – Treat any unprotected diaphragm with utmost care; this can be
damaged very easily.
NOTE for screw-in and flange version:
-
When installing the device, avoid high mechanical stresses on the pressure port! This will result in a shift of the characteristic curve or to damage.
-
In hydraulic systems, position the device in such a way that the pressure port points upward (ventilation).
-
Do not mount the device in a pneumatic flow rate!
-
Provide a cooling line when using the device in steam piping and clarify the material compatibility.
-
The measuring point must be designed in such a way that cavitation and pressure surges are avoided.
-
If a gauge pressure measuring device is installed with the pressure port pointing upwards, ensure that no liquid drains off on the device. This could result in humidity and dirt blocking the gauge reference in the housing and could lead to malfunctions.
-
The permissible tightening torque depends on the conditions on site (material and geometry of the mounting point). The specified tightening torques for the probe must not be exceeded!
NOTES -
for mounting outdoors or in a moist environment (for screw-in and flange version)
-
Please note that your application does not show a dew point, which causes condensation and can damage the probe. There are specially protected pressure measuring devices for these operating conditions. Please contact us in such case.
-
Connect the device electrically straightaway after mounting or prevent moisture penetration, e.g. by a suitable protective cap. (The ingress protection specified in the data sheet applies to the connected device.)
-
Select the mounting position such that splashed and condensed water can drain off. Stationary liquid on sealing surfaces must be excluded
-
The outgoing cable must be routed downwards. If the cable needs to be routed upwards, this must be done in an initially downward curve
-
Mount the device such that it is protected from direct solar radiation. In the most unfavourable case, direct solar radiation leads to the exceeding of the permissible operating temperature
-
For devices with gauge reference in the housing (small hole next to the electrical connection), install the device in such a way, that the gauge reference is protected from dirt and moisture. Should the device be exposed to fluid admission, the functionality will be blocked by the gauge reference. An exact measurement in this condition is not possible. Furthermore, this can lead to damages on the device.
Mounting steps for probes
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.
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 high viscosity 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)

---|---
The supply corresponds to protection class III (protective insulation).
NOTE – Use a shielded and twisted multicore cable for the electrical
connection.
NOTE – When routing the cable, following bending radiuses have to be
complied with: static installation: 10-fold cable diameter dynamic
application: 20-fold cable diameter
NOTE – The PTFE filter, located at the cable end on the air tube, must
neither be damaged nor removed.
Electrical installation
Connect the device electrically according to the information specified on the manufacturing label, the following table, and the connection circuit diagram.
Pin configuration:
| Electrical connections | cable colors (IEC 60757) |
|---|---|
| Supply + Supply- | WH (white) BN (brown) |
| Supply T+ (with Pt 100) Supply T- (with Pt 100) Supply T- (with Pt 100) | YE |
(yellow)GY (grey) PK (pink)
Shield| GNYE (green-yellow)
Wiring diagrams:
2-wire-system current (pressure) / 3-wire-system (temperature)
2-wire system (current) HART R
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 – 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.
with
RL : resistance of connecting cable in Ω
ρ : specific resistance in Ω mm²/m
l: cable length in m
A: cross section of conductor in mm²
with Vtot : total voltage drop
Road: load resistance (to be taken out of the current data sheet)
**following condition has to be fulfilled:
with VS: planned supply voltage
VS min** : minimal supply voltage (to be taken out of the current data
sheet)
HART communication (for H-Devices)
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
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:
with 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:
with
U:** power supply in [VDC] The resistance must be at least 240 .
| Danger of death from airborne parts, leaking fluid, electric shock
- 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.
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 data sheet.
Maintenance
| Danger of death from airborne parts, leaking fluids, electric shock
- Always service the device in a depressurized and de-energized
condition!
---|---
| Danger of injury from aggressive fluids or pollutants
- Depending on the measured medium, this may constitute a danger to the operator.
- Wear suitable protective clothing e.g. gloves, safety goggles.
If necessary, clean the housing of the device using a moist cloth and a non-
aggressive cleaning solution.
During the cleaning processes, note the compatibility of the cleaning media
used in combination with the media-wetted materials of the pressure measuring
devices. Permissible concentrations and temperatures must be observed.
Verification/validation by the user is essential.
Deposits or contamination may occur on the diaphragm/ pressure port in case of
certain media. Depending on kind and quality of the process, suitable cyclical
maintenance intervals must be specified by the operator. As part of this,
regular checks must be carried out regarding corrosion, damage of
diaphragm/seal(s) and signal shift. A periodical replacement of the seal(s)
may be necessary.
If the diaphragm is calcified, it is recommended to send the device to
BD|SENSORS for decalcification. Please note the chapter Service / repair
below.
NOTE – Wrong cleaning or improper touch may cause an irreparable damage
on the diaphragm. Therefore, never use pointed objects or pressured air for
cleaning the diaphragm.
