    Bimetallic thermometer


    • Simple and robust design.
    • Less expensive than other thermometers.
    • Bimetallic thermometers are fully mechanical and do not require any power source to operate.
    • Easy installation and maintenance.
    • Nearly linear response to temperature change.
    • High precision bimetallic temperature gauge is suitable for 0~150℃ wide temperature ranges.
    • The pointer of the bimetallic thermometer covers 1/3, -2/3 of the length of the shortest graduation line.


    Bimetallic thermometers can directly measure the temperature of liquid, steam and gas media and solid surfaces in the atmosphere of 0°C~300°C in various production processes, and are widely used in petroleum, chemical, metallurgy, textile, food and other industries.

    Q1: What is a bimetallic thermometer?
    A1: The bimetallic thermometer is a field detection instrument for measuring low and medium temperatures. The bimetallic thermometer can directly measure the temperature of liquid, steam and gas mediums in the range of 0℃~2000℃ in various production processes.

    Q2: How does a bimetallic thermometer work?
    A2: The bimetallic thermometer is a thermal bimetallic sheet wound into a spiral shape as a temperature sensing device, and it is installed in a protective sleeve. One end is fixed, called the fixed end, and the other end is connected to a thin shaft, called the fixed end. free end. A pointer is mounted on the free-end spool. When the temperature changes, the free end of the temperature-sensing device rotates accordingly, driving the pointer on the thin shaft to change the angle, and indicating the corresponding temperature on the dial. This is how bimetallic thermometers work.

    Q3: Advantages of Bimetallic Thermometers
    A3: The biggest advantage of the bimetal thermometer is that it has good shock resistance and is sturdy, but its accuracy is low and can only be used in industry, with an accuracy grade of 1 to 2.5. The bimetallic thermometer is suitable for medium and low-temperature on-site detection. It can directly measure the temperature of gas, steam and liquid, with clear indication and good mechanical strength.

    Tips: Bimetallic Thermometers in Industrial Applications

    In industrial applications, bimetallic thermometers can measure the temperature of liquids or gases in pipelines. Because they can work without any energy, they are a very cost-effective on-site indicator thermometer.

    Reliable quality and easy to install
    I was impressed with the quality of the bimetallic thermometer and the design of the metal double-layer thermometer allowed for more accurate measurements. After purchasing it, I found it very easy to install without too much hassle, even for a non-professional. Using it in my home to monitor temperature changes from 0~150℃ gives me added peace of mind.
