SITRANS TH320 — Siemens

Head-mounted transmitter for the form B connection head, HART-capable, galvanically isolated, approved up to SIL 2/3 and Ex ia.

SITRANS TH320

The TH320 sits in the sensor's connection head and converts the sensor signal into 4…20 mA right there — the cable to the control cabinet then carries an interference-proof current signal instead of a sensitive thermoelectric voltage. One input, one galvanically isolated two-wire output, configuration via HART.

We supply it fitted and programmed to your measuring range, together with the sensor, connection head and thermowell — or separately as a spare part.
