Description
5 DESCRIPTION
5.1 Area of application
The Type 8222 ELEMENT conductivity meter is intended for the measurement of the conductivity.
Thanks to 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 Construction of the 8222
The device comprises:
• A sensor for measuring physical parameters, comprising:
- 2 electrodes which measure an impedance in Ohm
- a Pt1000 temperature probe measuring a resistance.
• An acquisition / conversion module for the process values measured:
- acquisition of the impedance measured in Ohm
- conversion of the measured impedance into conductivity units
- acquisition of the resistance measured and conversion into temperature
• An electrical housing which can include a display module. The display module has a navigation button used
to read and/or configure the parameters of the device. The display module is available as an accessory (see
chpt. 11).
One device variant of the device with 2 transistor outputs and a 4...20 mA output operates on a 2-wire system
and requires a power supply of 14...36 V DC. For such a device variant, electrical connection is done via an M12,
5-point, male fixed connector.
One device variant of the device with 2 transistor outputs and two 4...20 mA outputs operates on a 3-wire system
and requires a power supply of 12...36 V DC. For such a device variant, electrical connection is done via an M12,
5-point, male fixed connector and an M12, 5-point, female fixed connector.
5.3 Conductivity sensor
The device is fitted with a sensor measuring the conductivity. The sensor is pined together with the electronic
module and cannot be dismantled.
The sensor itself comprises a Pt1000 temperature probe and 2 electrodes (in stainless steel for sensors with a
C constant of 0.01 or 0.1, in graphite for sensors with a C constant of 1.0).
The conductivity of a fluid is the capacity of this fluid to conduct electrical current thanks to the ions in the fluid.
An alternating voltage is applied to the electrode terminals: the current measured is directly proportional to the
conductivity of the solution.
