Overview

The WTZ-280 pressure thermometer WTQ-288 pressure thermometer manufacturer uses a pressure thermometer based on the relationship between the saturated vapor pressure and temperature of the evaporated liquid in a closed temperature measurement system to measure temperature. The pressure thermometer and the series of temperature measuring instruments developed from this overcome the shortcomings of the original instrument, such as single performance, poor reliability, and large temperature package area. The temperature measuring element volume is reduced to 1/30 or 1/60 of the original, and the sensor thermistor is creatively installed inside the temperature measuring element to achieve the temperature measurement function of mechatronics integration.

Working Principle:

The principle of a pressure thermometer is based on the relationship between the saturated vapor pressure and temperature of the evaporated liquid in a closed temperature measurement system, and is used for temperature measurement. When the temperature bulb senses a temperature change, the saturated vapor in the closed system generates corresponding pressure, causing a change in the curvature of the elastic element and causing displacement at its free end. The displacement is then converted into an indicator value by a gear amplification mechanism. This thermometer has the characteristics of small temperature bulb volume, fast reaction speed, high sensitivity, and intuitive reading. It almost combines all the advantages of glass rod thermometers, bimetallic thermometers, and gas pressure thermometers. It can be manufactured as shock resistant and corrosion-resistant, and can achieve remote transmission of contact signals, thermal resistance signals, etc0-10mAor4-20mASignal. It is currently the most widely used and comprehensive mechanical temperature measuring instrument in terms of performance.

Applicable places and working conditions:

Pressure type thermometers are suitable for measuring the temperature of various media that do not corrode copper in industrial settings. If the media has a corrosive effect, anti-corrosion type should be selected. Pressure thermometers are widely used in the mechanical, textile, chemical, pharmaceutical, and food industries for temperature measurement and control in production processes. The anti-corrosion pressure thermometer is made of all stainless steel material and is suitable for temperature measurement of neutral corrosive liquid and gas media.
