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℃~300℃ 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: How to choose a bimetallic thermometer?
- Confirm the temperature range of the bimetallic thermometer.
- Select the dial size of the bimetal thermometer, usually 60mm, 80mm, 100mm, 150mm, etc.
- Choose the connection method between the dial and the temperature sensing tube, usually axial, radial, universal, etc.
- Confirm the diameter and insertion depth of the temperature-sensing tube.
- Confirm the fixing method of the temperature sensing tube. There are several methods such as fixed thread, movable thread, ferrule thread, flange fixing, etc., depending on the site conditions.
- Confirm the thread size. The default thread size of the sisco bimetallic thermometer is 27*2, and customization is supported.
