類型 8202 - pH or oxidation-reduction potential (ORP) transmitter, ELEMENT design

類型描述

The transmitter Type 8202 is a compact device for measuring the pH value in clean, dirty, sulphide- or protein-containing liquids or for measuring the oxidation-reduction potential (ORP) value in clean, dirty, sulphide- or protein-containing liquids as well as liquids that have a low conductivity. Thus, due to the measuring device’s design, Bürkert has simplified installation and maintenance work. The device Type 8202 is available in two variants. The first one, the so-called ELEMENT standard, is proposed with either three adjustable outputs (two digital outputs and one analogue output) or 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. selection of pH/ORP measurement, measuring range, units, calibration, limit values) and for process value display. The second variant, the so-called ELEMENT neutrino, is a 2-wire device without a display, equipped either with a 4...20 mA current output or with a digital communication mode via IO-Link or büS (Bürkert system bus based on CANopen). The Type 8202 device converts the measurement signal and calculates the output signals, which are provided via one or two M12 plug connections for the ELEMENT standard variant as well as via one M12 plug connection or on a terminal strip via a cable gland for the ELEMENT neutrino variant. The device in the ELEMENT standard variant shows several values in different measuring units (if a display is mounted).
