Cement Plant Wear-resistant Thermocouple introduction

Wear-resistant Thermocouple is widely used in different industries,Cement Plant Wear-resistant Thermocouple application is limited by its temperature measuring range. The temperature measuring principle of special Cement Plant Wear-resistant Thermocouple in cement factory is based on the characteristic that the resistance value of conductor or semiconductor changes with the change of temperature.Cement Plant Wear-resistant Thermocouple can also be far transmission of electrical signals, high sensitivity, strong stability, interchangeability and accuracy are relatively good, but the need for power supply excitation, can not be instantaneous measurement of temperature changes.



Industrial thermal resistance generally adopts Cement Plant Wear-resistant Thermocouple,Pt10, Cu50, Cu100, platinum thermal resistance temperature measurement range is generally minus 200-800℃, copper thermal resistance is minus 40 to 140℃.Thermal resistance is the same type as thermocouples, but it does not require compensating wires and is cheaper than explosion-proof thermocouples.

1 The principle of temperature measurement is based on the conductor (or semiconductor) resistance with the temperature of the property to measure, explosion-proof cement plant special thermal resistance measurement range of negative 00~500 degrees, commonly used platinum resistance (Cement Plant Wear-resistant Thermocouple, Pt10), copper resistance Cu50 (negative 50-150 degrees).

2 The characteristics of the Cement Plant Wear-resistant Thermocouple signal of the cement plant, the thermal resistance itself is the resistance, the temperature change, the resistance produces positive or negative resistance value change;Thermal coupling, on the other hand, produces a change in the induced voltage, which varies with the temperature.

3  The temperature range detected by two kinds of sensors is different. The Cement Plant Wear-resistant Thermocouple is generally detected in the temperature range of 0-150 degrees, and the highest measurement range can reach about 600 degrees (of course, negative temperature can be detected).
