The use principle of pressure stainless steel customized High temperature pyrometer

The all-stainless steel customized High temperature pyrometer has good performance and is gradually being widely used. Like other pyrometers, it also has its own working principle. Today I want to introduce to you the working principle of the stainless steel customized High temperature pyrometer. Let's take a look together.

The customized High temperature pyrometer uses the liquid, gas or saturated vapor in a closed container to produce volume expansion or pressure change as a measurement signal after heating. Its basic structure is composed of three parts: a temperature bulb, a capillary tube and an indicator. It is used in production One of the methods of process temperature control. The pressure type temperature measurement system is still a very widely used measurement method for indicating and controlling the temperature on the spot. The advantages of the pressure type thermometer are: simple structure, high mechanical strength, not afraid of vibration. Low price, No external energy is required. The instrument sealing system must be replaced, and the installation accuracy is relatively low. It is easy to install. The transmission distance of the capillary tube is limited. The working range of the pressure thermometer should be within the measurement range and the display meter and the temperature bulb should be in a horizontal position as much as possible .

The above content is the principle of using the pressure all stainless steel double customized High temperature pyrometer. What we need to pay attention to is that the temperature bulb mounting bolts used for installation will cause temperature loss and inaccurate temperature. The installation should be insulated and try to make the temperature bulb Work in a vibration-free environment. For more exciting content, please continue to pay attention to our website.
