CT-213 Explosion-proof Temperature

Description

This product is a general-purpose temperature sensor suitable for temperature measurement applications in non-hazardous environments. It features a metal protective tube and junction box design, effectively protecting the internal sensing elements and providing a stable and accurate temperature signal output.

This model is not explosion-proof certified and is not suitable for use in areas with explosive gases, dust, or hazardous conditions (such as Zone 1/Zone 2). It is recommended for use in general industrial equipment, mechanical temperature control, heating systems, and ambient temperature monitoring.
