Area of application

The neutrino transmitter 8222 is intended to measure the conductivity
of a fluid.
The transmitter is used to transmit the conductivity measured to a
4-20 mA loop.

General description

5.2.1.

design

The neutrino transmitter 8222 comprises:
• A sensor for measuring physical parameters, comprising:
- 2 electrodes which measure an impedance in Ohm
- a Pt1000 temperature probe which converts the temperature
of the fluid into resistance (in W).
• An acquisition / conversion module of measured physical data:
- acquisition of the measured impedance in Ohm
- conversion of the measured impedance into conductivity units
- acquisition of the measured resistance
temperature.
Description
and conversion into
english
The neutrino transmitter 8222 operates on a 2-wire system and requires
a power supply of 12-36 VDC. Electrical connection is made:
- Either by 1 M12 5-pin male fixed connector
- Or via a cable gland using a 5-pin terminal strip.
5.2.2.

conductivity sensor

The neutrino transmitter 8222 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 sensor 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.
