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:
C
B
A
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).
B: An electronic module for the acquisition / conversion of the meas-
urable variables:
- acquisition of the conductivity in µS/cm,
- 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.
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.
