Description

5 DESCRIPTION

5.1 Area of application

The device is intended to measure the conductivity. Thanks to one or two fully adjustable transistor outputs, the device can be used to switch a solenoid valve, activate an alarm and, thanks to one or two 4-20-mA current outputs, establish one or two control loops.

5.2 Knowing the device

The device comprises:
A: an electrical housing which can include a display module. The display module has a navigation button to read and/or configure the parameters of the device. The display module is not delivered with all the versions of the device but it is available as an accessory (see chap. 11).
A
B: An electronic module for the acquisition / conversion of the meas­urable variables:
- acquisition of the conductivity in µS/cm,
B
C
The device operates on a 3 wire system and needs a 12-36 V DC power supply.
The electrical connection is made, depending on the version, via a 5 pin, male, M12 fixed connector or via a 5 pin, male, M12 fixed connector and a a 5 pin, female, M12 fixed connector.
- acquisition of the temperature,
- calculation of the conductivity at a temperature of 25 °C,
- conversion of the conductivity into a resistivity at 25 °C in Ohm/cm.
C: a conductivity sensor comprised of:
- a pair of magnetic coils,
- a sensor holder in PP, PVDF or PEEK equipped with an integrated temperature probe.
The conductivity sensor is pined together with the electronic module and cannot be dismantled.
The conductivity sensor comprises a temperature probe to compensate the temperature when measuring the conductivity.

8 INSTALLATION AND WIRING

8.1 Safety instructions

Risk of injury due to electrical voltage.
▶ If a 12-36 V DC powered version is installed either in a wet environment or outdoors, all the electrical
voltages must be of max. 35 V DC.
▶ Disconnect the electrical power for all the conductors and isolate it before carrying out work on the system.
▶ All equipment connected to the device shall be double insulated with respect to the mains according to the
standard IEC 61010-1:2010.
▶ Observe all applicable accident protection and safety regulations for electrical equipment.
Risk of injury due to high pressure in the installation.
▶ Stop the circulation of fluid, cut off the pressure and drain the pipe before loosening the process connections.
Risk of injury due to high fluid temperatures.
▶ Use safety gloves to handle the device.
▶ Stop the circulation of fluid and drain the pipe before loosening the process connections.
Risk of injury due to the nature of the fluid.
▶ Respect the regulations on accident prevention and safety relating to the use of aggressive fluids.
WARNING
Risk of injury due to non-conforming installation.
▶ The electrical and fluid installation can only be carried out by qualified and skilled staff with the appropriate
tools. ▶ Install appropriate safety devices (correctly rated fuse and/or circuit-breaker). ▶ Observe mounting instructions of the fitting.
Risk of injury due to unintentional switch on of power supply or uncontrolled restarting of the installation.
▶ Protect the installation against unintentional power-up. ▶ Guarantee a set or controlled restarting of the process subsequent to any intervention on the device.
22
WARNING
Risk of injury if the fluid pressure/temperature dependency is not respected.
▶ Observe the fluid temperature-pressure dependency according to the material of the conductivity sensor
holder (see the technical data of the device) and according to the materials the fitting is made of (see the
operating instructions of the fitting used).
▶ Observe the pressure equipment directive 97/23/CE.
