WSS-581NH2 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 thermoco

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: Δ = Δ 1 + / - 0.5% FS
Δ 1 is thermocouple (resistance) basic error, FS is measuring range
Temperature transmission: two-wire system (4 ~ 20 mA), transmitter minimum working voltage is 12V, maximum 35 V, rated voltage 24V
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℃
