Conductivity meter • Analog 4…20 mA output • Universal process connection • Three cell constants for covering a wide measuring range • Temperature compensated measurement Type 8222 neutrino can be combined with… Type 8611 eCONTROL Universal controller Type 8619 multiCELL Transmitter/Controller The Bürkert neutrino meter Type 8222 is a compact device designed for measuring the conductivity of fluids. The conductivity meter consists of a sensor plugged-in and pined to an enclosure with cover, containing the electronic module. The sensor holder comprises a cell with two electrodes and a Pt1000 temperature sensor. The sensor itself is available with three different cell constants C, these with C = 0.01 or 0.1 are fitted with stainless steel electrodes and this with C = 1.0 is fitted with graphite electrodes. The neutrino conductivity meter Type 8222 is available with one 2-wire 4…20 mA current output and with two different connections: either a G 1½ union nut for adaptor with G 1½ external threaded sensor connection or a G ¾ threaded holder for screwing into an adaptor with G ¾ internal thread sensor connection.

8222 ELEMENT neutrino Principle of operation Conductivity is defined as the ability of a solution to conduct electrical current. The load carriers are ions (E.G. dissolved salt or acids). In order to measure conductivity 2 electrodes are used which are set at a fixed distance apart and with a known specified surface. An AC voltage source is connected to the electrodes. The measured current is a direct function of the conductivity of the solution. The conductivity meter is a two-wire device, which requires a power supply of 12…36 V DC. The conductivity meter can be fitted with 3 different sensors...
