Description
The Bürkert Type 8222 conductivity meter is suitable for measuring the conductivity of liquids.
The sensor element consists of a cell with two electrodes and a Pt1000 temperature sensor. The sensor itself is available with three different cell constants C. These are made of stainless steel for sensors with a constant C of 0.01 or 0.1 cm- 1 and graphite for sensors with a constant C of 1.0 cm- 1. The design of the measuring device simplifies Bürkert installation and maintenance work.
The device type 8222 is available in two versions.
The first, the so-called ELEMENT Standard, is offered either with three adjustable outputs (two digital outputs and one analog output) or with four adjustable outputs (two digital outputs and two analog outputs) and can be equipped with a display. The display is only used for commissioning, configuration (e.g. Measuring range, units, calibration, limit values) or as process value display.
The second variant, the so-called ELEMENT neutrino, is a 2-wire device, without display, with a 4…20 mA current output or with a digital communication mode, which can communicate either via IO-Link or in bus (Bürkert system bus based on CANopen).
Both versions are available with a G 1½" union for installation in an adapter with a G 1½" external thread sensor connection, which is connected to the process. The variant ELEMENT neutrino is also available with a G ¾" external thread for screw-in into an adapter with G ¾" internal thread sensor connection.
The type 8222 device converts the measurement signal and calculates the output signals, which are provided for the standard ELEMENT version via one or two M12 connectors or, for the neutrino ELEMENT, via an M12 connector or on a terminal strip via a cable gland. The device in the Standard variant ELEMENT shows different values in different measuring units (if a display is mounted).
