Resistance thermometer WTh 30 for hygienic processes.

Application
For temperature measurement in tanks and pipelines and applications requiring hygienic process connections, materials and processing. Specially suitable for food technology, pharmaceutical and biotechnology applications due to the compact design and the high accuracy.

Description
WTh 30 consists of a rugged stainless steel housing with variable process connections and a Pt 100 measurement insert which is directly integrated in a thermowell. The change in resistance depending on the measured temperature can be used directly or detected by a transducer and converted into a 4–20 mA output signal. The instrument is connected by means of a compact M12 plug connection.
