Product Overview

The WZPK-440 Explosion Proof Pt100 RTD Temperature Sensor is designed for industrial temperature measurement in hazardous areas.

It features a Pt100 platinum resistance element, an explosion-proof terminal head, and a stainless steel flanged thermowell.

The DN25 PN16 RF flange allows installation on compatible pipelines and process equipment. The thermowell provides a protective barrier between the sensor and the process medium.

With a measuring range of -20 to 200°C and an insertion length of 190 mm, this product is suitable for temperature monitoring in chemical plants, oil and gas facilities, and other industrial process systems.

Specifications can be customized according to customer requirements.
