The bimetal thermometer is engineered for liquid, steam, and gas temperature measurement within temperature range of -60 Deg. C to +500 deg. C. It is ideal for severe environment application.

The temperature measuring instrument is a combination of thermocouple, RTD, temperature transmitter, and bometal thermometer. In Addtion to on-site temperature indication, it also supports transmitting signals from thermocouple, resistance temperature indicators, or 2 wire temperature transmitters.

Main Technical Parameters

Measuring range: -60 to 500 Deg. C

Deviation of remote electricity signal:

a.     Graduation: E (NiCr-CuNi) allowed deviation ±2.5 Deg. C or 0.75%t

b.    Graduation: K (NiCr-NiSi) allowed deviation ±2.5 Deg. C or 0.75%t

c.     Graduation: Pt100 (platinum RTD) allowed deviation

Grade A: ± (0.15 + 0.002 ︱t︱)

Grade B: ± (0.30 + 0.005 ︱t︱)

d.    Basic error with temperature transmitter: △ = △1 ± 0.5% FS

△  1 is thermocouple (RTD) allowed basic error of corresponding output

FS is measuring range

Transmitter method of temperature transmitter: 2 wire (4-20mA)

Working voltage of transmitter: minimum 12V, max 35V, rated working voltage: 24V

Normal Working Environment:

a.     Ambient temperature: -25 Deg. C to 80 Deg. C (max 70 Deg. C for hazardous area)

b.    Relative humidity: 5% to 95%

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

d.    No corrosive mediums in surrounding environment

Ambient temperature effect: ≤0.05% / 1 ℃
