You will first need an EX sensor to configure your EX measuring point: for pH the SensoLyt® 650-7 EX with a freely selectable EX electrode; for conductivity an 4-electrode measuring cell of the TetraCon® 700-… EX series.

Matching this, we offer EX monitors you can easily and quickly connect to EX sensors with open cable ends. Depending on the measuring values to be processed (measured value without or with temperature), you decide on 1 or 2 analog outputs.

The power supply of these elements installed in the zone by an intrinsic power circuit is the isolated amplifier of the WG 21 A7 series, optionally equipped with a 24 V AC/DC auxiliary voltage or the option for HART® communication.
