Bürkert Conductivity Meter, ELEMENT Design

Bürkert Type 8222 The Bürkert conductivity meter Type 8222 is designed for measuring the conductivity of liquids. The sensor element comprises a two-electrode cell and a Pt1000 temperature probe. 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 of graphite for sensors with a constant C of 1.0 cm- 1. Thus, due to the measuring device’s design, Bürkert has simplified installation and maintenance work. The Type 8222 device is available in two variants. The first one, the so-called ELEMENT standard is proposed either with three adjustable outputs (two digital outputs and one analogue output) or with four adjustable outputs (two digital and two analogue) and can be equipped with a display. The display is only required for start-up, configuration (e.g. measuring range, units, calibration, limit values) or as a 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 that can communicate either via IO-Link or in büS (Bürkert system bus based on CANopen). Both variants are available with a G 1½" union nut for installation in an adapter with a G 1½" external thread sensor connection that is connected to the process. The ELEMENT neutrino variant is also available with a G ¾" external thread for screwing into an adapter with a G ¾" internal thread sensor connection. The Type 8222 device converts the measurement signal and calculates the output signals, which are provided via one or two M12 plug connections in the ELEMENT standard variant or via an M12 plug connection in the ELEMENT neutrino variant or on a terminal strip via a cable gland. The device in the ELEMENT standard variant shows different values in different measuring units (if a display is installed).
