CE mark, declaration of conformity

The device has been designed to meet the highest safety standards, has been tested and has left the factory in a condition that is safe for operation. The device complies with the applicable standards and regulations listed in the EU Declaration of Conformity and has CE marking on nameplate.

INSTALLATION

General recommendation

The depth probes are installed in places where the liquid level is measured in wells, tanks, boreholes, etc. The probe is immersed in the measured medium. A special cable extends above the medium level and can be connected directly to the device cooperating with the probe or to the junction box.
The probe can be hung on the power cable, e.g. by using Aplisens SG cable hanger (item 1 in Fig. 1). In the event of frequent removal of the probe or when there is a risk of catching on protruding elements during pulling up, it is recommended to hang the probe on a steel cord using the carrying eye (item 2 in Fig. 1 – does not apply to SGE-16 probes).

Figure 1. Mounting brackets for probes.

The probe with an additional Teflon shielding on the cable should be hung on a carrying cable or on an internal cable (do not grab the Teflon shield). Hang the probe in Ex version with the grounding cord only by the lifting eye on an additional supporting wire.

Immediately before placing the SGE-25S or SGE-25C probe in the measured medium, remove the protective cover from the probe separator. During installation, protect the probe against mechanical shocks.

Figure 2. Probes diaphragm cover for SGE-25S and SGE-25C.

A special cable extends above the medium level and can be connected directly to the device cooperating with the probe or to the junction box. If the probe is to be in the current or in the turbulence area, it should be installed in a protective pipe, e.g. made of PVC.

ELECTRICAL CONNECTION

Cable connection

All connection and assembly activities must be performed with the power supply disconnected and other external voltages, if used.
Incorrect connection of the probe may endanger safety.
Risk of electric shock and / or ignition in hazardous areas.

Make the electrical connection in accordance with the diagram in fig. 3 or 4. If the transmission line is run in an open space, to remote rooms, it is recommended to install a junction box, e.g. type PP by Aplisens S.A., in order to connect the probe cable with the rest of the transmission line. The box should have an IP65 protection degree and at the same time be unsealed enough to ensure “breathing” of the probe measuring element through the capillary which is part of the cable. Do not allow the capillary outlet to become contaminated or water to enter the capillary. In the case of a long transmission line, it is recommended to run the section from the end of the probe cable using a “twisted pair”, and it is also advantageous to equip the entrance to the cooperating devices with a surge protection device, e.g. the UZ-2 system by Aplisens S.A..

Power supply

Power supply voltage

Supply cables may be live.
There is a risk of electric shock and/or explosion.

Installation in potentially explosive atmospheres must comply with local standards and regulations.

36 V DC

• TR version- made for measurements in fast-moving processes.
  **- special version 8 V DC.

Resistance load in supply line

Power line resistance, power source resistance and additional series resistances increase the voltage drops between the power source and the probe transducer. The maximum current under normal operating conditions is 0.02 A. The maximum value of resistance in the supply circuit (together with the supply line resistances) is given by the curves:

where:
Usup – voltage at the terminals of the loop power supply 4…20 mA [V].
Umin – minimum probe voltage ➔ Table 2.
RLmax – maximum resistance of the supply line [Ω]

Shielding

The cable shield (green wire) is led out from the probe’s power supply and measurement cable.
The manufacturer recommends connecting the probe cable shield to the measuring system grounding point. The earthing of the cable screen is especially justified in the environment of high EMC disturbances. In a battery-assisted piezometric stand, the cable screen may or may not be grounded.

Overvoltage protection

The probes may be exposed to switching or other overvoltage, for example due to lightning. Surge diodes are used to protect against overvoltage between the wires of the transmission line. In order to protect against overvoltage between the transmission line and the earth or the housing (against which the diodes connected between the lines of the line are not protected), standard and Exi probes.
In the SA version, they are equipped with additional protection in the form of overvoltage limiters.
Additionally, an external protective device can be used, e.g. the UZ-2 system by APLISENS S.A.

Final Inspection of cabling

After completing the electrical installation of the probe it is necessary to check the following:

• is the probe connected according to the information given in section ➔ Cable connection;
• when using a junction box, that the glands are tightened;
• are the diaphragm covers (SGE-25S and SGE-25C) removed.

MAINTENANCE

Periodic inspections

Periodic inspections should be carried out in accordance with the standards applicable to the user.
During the inspection it is necessary to check the condition of the head (absence of loosening and leakage), separating diaphragms (tarnish, corrosion) and the electrical connection (checking the condition of the cable), as well as the stability of the holder (if used). Check for signs of mechanical damage in the form of impact marks or dents.

Zero” check

Every 2 years or in accordance with the user’s standards, check the probe’s “zero” by pulling the probe above the liquid mirror and reading the output signal. In case of excessive deviation of the indication in “zero”, the probe should be returned to the manufacturer for correction of the characteristics.

Non-periodic inspections

If the probe has been subjected to mechanical damage, pressure overload, hydraulic impulses, electrical surges, deposits, crystallization of the medium, etching of the diaphragm, or if the probe is found to be working incorrectly, the device should be inspected. Check the condition of the diaphragm, clean it, check the electrical functionality and processing characteristics.

If the signal is missing in the transmission line or its value is incorrect, check the power supply line, the state of connections on terminal strips, connections, etc.
Check the correct value of the supply voltage and the resistance of the load.

Cleaning/washing

To remove impurities from the external surfaces of the probe wipe it with a cloth dampened in water.

Diaphragm cleaning

The only possible method of cleaning the probe diaphragms is to dissolve the sludge produced.

Do not remove deposits and impurities from the probe diaphragms, which are formed during operation, mechanically using tools, since the diaphragms and the probes can be damaged.

Spare parts

Parts of the probe that may be worn or damaged and must be replaced: cable and gland seals.
The cable and seals can only be replaced by the manufacturer.

Repairs

Faulty or non-operational probe shall be provided to the manufacturer or an authorized representative.

Returns

In the following cases the, probe should be returned directly to the manufacturer:

• need for repair;
• need for factory calibration or „zero” calibration;
• replacement of improperly selected/shipped probe.

SCRAPPING, DISPOSAL

Worn or damaged devices shall be scrapped in accordance with WEEE Directive (2012/19/EU) on waste electrical and electronic equipment or returned to the manufacturer.

When installing and using Ex probes, the User’s Manual EN.IO.SGE and Explosion-proof Device Manual EN.IX.SGE should be used.

Using probes in hazardous area

The probes are produced in accordance with the requirements of the following standards:
EN IEC 60079-0:2018; EN 60079-11:2012; EN 50303:2000.
The probes may operate in areas where there is a risk of explosion, in accordance with the rating of the explosion protection design:

II 1G Ex ia IIC T4/T5/T6 Ga
II 1G Ex ia IIB T4/T5/T6 Ga (for probe with Teflon sheathed cable)
I M1 Ex ia I Ma
KDB 09ATEX 007X

Permissible input parameters (based on data from the certificate KDB

09ATEX007X and validation documentation)

• The probes should be powered from co-operating power supply and measuring devices with relevant intrinsic-safety certificates, whose parameters of outputs to the danger zone should not exceed the acceptable power supply parameters for the probes given in points 3a) and 3b).
• Probes in “SA version” should be powered from devices with galvanically separated power supply.
• Minimum probes power supply 9 V DC.
• The probe is an intrinsically safe device with protection level “ia” when the supply circuit has protection level “ia” or an intrinsically safe device with protection level “ib” when the supply circuit has protection level “ib”.

a ) Acceptable input parameters for power supply with linear characteristics:
Ui = 28 V DC Ii = 0,1 A
b) Acceptable input parameters for power supply with trapezoidal and rectangular characteristics:
Ui = 28 V DC Ii = 0,08 A
c ) Input capacity and inductance: Ci = 25 nF; Li = 0,4 mH
*) The capacitance and inductance of the cable must be taken into account, which for a permanently connected wire are:
Ck = 0,2 nF/m i Lk = 1 µH/m.
The input capacitance Cw and inductance Lw taking into account the parameters of the cable connected permanently is:
Cw = Ci + a x Ck = 25 nF + a x 0,2 nF/m; Lw = Li + a x Lk = 400 µH + a x 1 µH/m Where: – a – length of the cable permanently installed in the probe in metres.

„Pi” for all types of power supply: see table Z1.
