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: 4 Types of bimetallic thermometer
According to the connection direction of the pointer plate of the bimetal thermometer and the protective tube, the bimetal thermometer can be divided into four types.
- Axial type bimetallic thermometer: the pointer plate is connected vertically with the protective tube.
- Radial type bimetallic thermometer: the pointer plate is connected in parallel with the protective tube. sisco bimetal thermometers are radial-type bimetal thermometers.
- 135° bimetallic thermometer: the pointer plate is connected to the protective tube at 135°.
- Universal bimetallic thermometer: the connection angle between the pointer plate and the protective tube can be adjusted arbitrarily.
