Technical Parameters

Technical parameters

Measuring range: -60 ~ 500 ℃

Display accuracy: 1.5

Remote signal deviation:

A. Graduation: E (nickel chromium-copper nickel) allowable deviation ± 2.5 ℃ or 0.75% t

B. Graduation: K (nickel chrome-nickel silicon) allowable deviation ± 2.5 ℃ or 0.75% t

C. Graduation: Pt100 platinum resistor () allowable deviation:

Model

Note: customized based on requirements 

WSS series bimetallic thermometer with thermocouple (resistance) and temperature transmitter 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. It can also output two-wire signals directly, improve anti-interference performance during the process of long distance transmission. Favorable by users.
