The ELEMENT transmitters from Bürkert combine controllers, valves and sensors in a stainless steel housing with intelligent architecture. The 8202 ELEMENT neutrino transmitters (for pH or redox potential) and the 8222 (for conductivity), are high-performance yet economical versions without a display and provide an alternative to the ELEMENT transmitters with a display and keypad.
The new transmitters feature a patented variable electrical connection for pH electrodes. This makes it possible to use most pH electrodes with a 12 mm diameter and an S7 connection. Not only do users enjoy greater flexibility; a single standard transmitter can be used for all applications within the system. The option of selecting from three cell constants (0.01, 0.1 or 1) for measuring conductivity ensures maximum versatility when exchanging sensors, as well as adaptability to the required task.
An integrated pt1000 sensor allows integrated temperature compensation. The temperature value is provided as a second process variable in the unit, which can also be output as 4-20 mA signal. This eliminates the need for a separate temperature sensor, in addition to the separate costs of installation and operation.
