WSSP-411 RTD Bimetal Thermometer
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:
Class A: ± (0.15 + 0.002 t )
Class B: - (0.30 + 0.005 t )
D. Basic error with temperature transmitter: delta = delta 1 + / - 0.5% FS
delta 1 is thermocouple (resistance) basic error, FS is measuring range

Work environment:
A. environmental temperature: -25 ℃ ~ 80 ℃ (not higher than 70 ℃ in dangerous place)
B. relative humidity: 5% ~ 95%
C. mechanical vibration: f≤55Hz, amplitude < 0.15 mm
D. no corrosive medium in the environment
Environment temperature influence: ≤0.05%/1℃

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.
