Integrated Bimetal Thermometer

Brief Description

The WSSP-481 integrated bimetal thermometer isa temperature sensor for local display and remote signal transmission. It canindicate local temperature as well as transmit two-wire system signal ofthermocouple (resistance) and temperature transmitter. As a new generationthermometer, it's widely used in metallurgy, petrochemical, electric power,textile, food, national defense and other industries. It's integrated type withthermocouple, thermal resistance and temperature transmitter, suitable forlong-term working in harsh environment. Remote signal is of high accuracy andstability. TheWSSP-481 integrated bimetal thermometercan also output two-wire signals directly, improve anti-interferenceperformance during the process of long distance transmission. Favorable byusers.

Technical parameters

Measuring range:  -60 ~ 500 ℃

Display accuracy: 1.5

Remote signal deviation:

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

B. Graduation: K (nickel chrome-nickel silicon) allowabledeviation ± 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 errorwith temperature transmitter: Δ = Δ 1 + / - 0.5% FS

Δ 1 is thermocouple (resistance) basicerror, FS is measuring range

Temperaturetransmission: two-wire system (4 ~ 20 mA), transmitter minimum working voltageis 12V, maximum 35 V, rated voltage 24V

Work environment:

A.environmental temperature: -25 ℃ ~ 80 ℃(not higher than 70 ℃ in dangerous place)

B. relativehumidity: 5% ~ 95%

C. mechanicalvibration: f≤55Hz, amplitude< 0.15 mm

D. no corrosivemedium in the environment

Environmenttemperature influence: ≤0.05%/1℃
