With the update of technology, the pressure temperature is replaced by a bimetal thermometer and a digital thermometer and developed into a mechatronics, forming a transformer-specific temperature for the power industry.
A pressure thermometer is a touch temperature sensor that is made using a pressure or volume change of a liquid or gas as a function of temperature. The change in pressure causes the curvature of the reed switch to change and the displacement at the free end, indicating the change in temperature directly on the dial via the connecting rod and the drive tissue.
A more sensitive pressure thermometer consists of a warm pack, a capillary tube, a spring tube (Bourdon tube), a linked tissue, and a pointer. The temperature pack touches the object to be measured and performs heat exchange to reach the balance. The pressure (or volume) of the working substance that is filled in the closed thermopack, capillary and reed switch varies with temperature. The change in pressure causes the curvature of the reed switch to change and the displacement at the free end, indicating the change in temperature directly on the dial via the connecting rod and the drive tissue.
Under the premise that the degree of industrialization is increasingly planning, the demand for malls for pressure thermometers is constantly changing. It is still changing with the mall's requirements for the use of pressure thermometers. The general steam or gas pressure thermometer required on industrial equipment, the digital thermometer that transmits signals through the remote transmission cable in my glue, is still a bimetal thermometer for distance measurement and temperature, and the special pressure type used on professional equipment. Thermometers, as well as pressure thermometers for power equipment. They all have a wide range of applications and prospects. In the future development journey, it is still mainly to develop a new generation of pressure thermometers for the reliability and operational simplicity of the thermometer.
