Summary
Pressure type thermometer and the development of a series of temperature measuring instruments, the performance of the original instrument to overcome a single, poor reliability and temperature of the product, and the temperature measurement element to reduce the size of the original 1/30 or 1/60, the sensor thermal resistance installed in the temperature sensor to achieve the temperature measurement function. The formation of the liquid pressure type thermometer for temperature measurement instrument remote, shock resistance, corrosion resistance, electrical contacts, temperature signal transmission and multi function series temperature instrument. Is divided into two series, ordinary type and explosion-proof type.
Characteristic
(1) with small temperature measuring probe, high sensitivity, linear scale, long life and other characteristics.
(2) with remote output resistance signal (PT100), shock resistance, corrosion resistant function and high power switch signal etc..
(3) the structural form is the same as that of the international same kind, and can be used to replace the use of the import trade:
(4) the pressure type thermometer inside the liquid for the silicone oil. After the spring tube is formed by pouring

Summary
Pressure type thermometer for temperature measurement of liquid, gas and vapor within 20 meters. According to the difference of the medium, it can be divided into common type and anti-corrosion type. Ordinary type of liquid, gas and vapor, which is not corrosive, is used as a whole stainless steel material, which is suitable for the use of liquid and gas in neutral corrosion. Note: due to the saturated vapor pressure of the evaporated liquid and the characteristic of the temperature change, the user can use the 2/3 part of the scale.
