Bimetal thermometer selection data
Since one end of the spiral coil is fixed and the other end is connected to a pointer that can rotate freely, the amount of change in the volume of the two metals when the temperature changes is not the same, and therefore bending occurs. One end is fixed, and the other end is displaced with temperature change, and the displacement amount is close to a linear relationship with the temperature. The self-recording system is composed of a self-recording clock and a self-recording pen. The self-recording pen is connected with the magnifying lever and is operated by the sensing element. Therefore, when the bimetal feels a temperature change, the pointer can be indicated on a circular indexing scale. The temperature comes. The temperature range of this instrument is 200 ~ 650 °C, allowing about 1% of the two-way scale. This type of thermometer is similar to a rod-shaped glass liquid thermometer, but it can be used under higher strength requirements.
Changzhou Xinwang Instrument Co., Ltd. selects thermometers and pressure gauges for you, as well as level gauges and flowmeters. You are welcome to inquire the detailed information of the products! There are many kinds of products in Changzhou Chengheng Instrument Co., Ltd. There will be subtle differences in the product, so you can get more information by calling us. Wait for your call
3. When the user has special requirements, he must specify.
Bimetal thermometer specifications
On-site display of temperature, intuitive and convenient;
Safe and reliable, long life;
A variety of structural forms to meet different requirements.
Bimetal thermometer specifications working principle
The bimetal thermometer is based on a bimetallic strip wound into a loop shape. When one end is heated to expand, the pointer is rotated, and the working instrument displays the desired temperature value.

The bimetallic thermometer temperature sensing element uses a multi-turn straight spiral bimetal. One end is fixed, the other end (free end) is connected to the mandrel, and the axial thermometer pointer is directly mounted on the mandrel. The radial type structure indicator needle is connected with the mandrel through a corner spring. When the temperature changes, the free end of the temperature sensing element rotates, and the change value of the temperature of the measured medium is indicated on the dial via the mandrel drive pointer.
