Description

Product introduction:

Model: WSSP

Name: Bimetallic thermometer with thermal resistance or thermocouple

Manufacturer: Shanghai Automation Instrumentation Co., Ltd.

Application: WSSP Bimetallic thermometer with thermal resistance or thermocouple, both meet the demand of field temperature measurement, also meet the demand of long distance transmission, can be directly measured the temperature -80~500℃ of liquid, vapour and gas medium in the process of various production, as well as solid surface temperature.

Main Technical Parameters:

Range:-80~500℃

Accuracy class: Class 1.5

Deviation of far eastone electrical signal:

a. Degree: E(NiCr-CuNi) allowed deviation ±2.5℃/0.75%t

b. Degree: K(NiCr-NiSi) allowed deviation ±2.5℃/0.75%t

c. Degree: Pt100  Allowed deviation:

Class A：±（0.15+0.002∣t∣）

Class B：±（0.30+0.005∣t∣）

d. Intrinsic error with temperature transmitter:Δ=Δ1±0.5%FS

Δ1 is output intrinsic error corresponding thermocouple(thermal resistance)’s allowed deviation.

FS is measuring range.

Temperature transmitter transfer manner: Two wires(4~20mA)

Transmitter min working voltage is 12V, max working voltage is 35V, and rated working voltage is 24V.

Normal working environment:

Environment temperature: －25℃～80℃（hazardous areas is no more than 70℃）

Relative humidity: 5%～95%

Mechanical vibration: f≤55Hz, amplitude<0.15mm

There is not medium that may cause transmitter corrosive around the air.

Environmental temperature effect：≤0.05%/1℃
