Brief Description

WSS-Remote-bimetal-thermometer is a temperature sensor for local display and remote signal transmission. It can indicate local temperature as well as transmit two-wire system signal of thermocouple (resistance) and temperature transmitter. As a new generation thermometer, it's widely used in metallurgy, petrochemical, electric power, textile, food, national defense and other industries. It's integrated type with thermocouple, thermal resistance and temperature transmitter, suitable for long-term working in harsh environment. Remote signal is of high accuracy and stability. WSS-Remote-bimetal-thermometer can also output two-wire signals directly, improve anti-interference performance during the process of long distance transmission. Favorable by users.

Technical parameters
