Bimetal Thermometer

Bimetal Thermometer

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.



We mainly provide the following three styles of bimetal thermometers:


1.    Electrical contact style

Technical parameters

(1)  Accuracy: Class 1.5

(2)  Time constant: J < 40s

(3)  Withstand pressure of thermowell: 6.3 MPa

(4)  Contact capacity: rated power: 10 VA (noninductive), max. voltage: 220V AC, max working current: 1A (noninductive); normally open contact with upper and lower limits.

(5)  Counter assembly working temperature: -25 to 55 deg. C



2.    Shock resistance style

With great shock resistance, electrical contact bimetal thermometer can be used to directly measure the temperature of liquids. Steam and gases under harsh and vibrative environments. By filling oil into the thermometer, it can effectively avoid trembling of pointer caused by mechanical vibration. 


(1)  On-site temperature indication, direct and convenient

(2)  Multiply structure designs to meet varied demands; no mercury and easy for temperature reading

(3)  The thermowell is made of stainless steel and Mo-Ti alloy, offering fantastic pressure bearing and corrosion resistance performance.

(4)  Core-pulling style bimetal thermometer supports maintenance or core replacement without breakdown



3.    Omni-directional style

 Technical specifications

(1)  Nominal diameter of dial: 100mm, 150mm

(2)  Accuracy: 1.0, 1.5

(3)  Connection: M20 * 1.5, 1/2” NPT or customer to specify

(4)  Thermal response time ≤ 40s

(5)  Protection grade: IP55
