Bürkert Inductive Conductivity Meter, ELEMENT Design

The Bürkert inductive Type 8228 conductivity meter is used in many industrial processes where measurements are required in aggressive or concentrated media such as acids, alkalis or liquids with high salt contents and a wide measuring range. This can concern applications like cooling water monitoring (i.e. dilution control), industrial water treatment or the preparation and identification of cleaning liquids, for example in CIP (Cleaning in Place) processes. The device Type 8228 is available in two variants. The first one, the so-called ELEMENT standard is proposed either with two adjustable outputs (one digital and one analogue output) or with four adjustable outputs (two digital and two analogue outputs) and can be equipped with a display. The display is only necessary for start-up, configuration (e.g. measuring range, units, calibration, thresholds) or as a display of process values. The second variant, the so-called ELEMENT neutrino is a device without display, with a digital communication mode that can communicate either in IO-Link or in büS (Bürkert system bus based on CANopen). Both variants are available with a process connections either via a G 2 union nut for installation into a fitting Type S020 which is connected to the process, or via a clamp 2" according to ASME BPE (clamp 1.5" on request) for CIP applications.
