Product Description
Smart Adjustable Temperature Transmitter 4-20mA Integrated Temperature Sensor PT100
This product is customized, please contact our engineers to give you the best advice.
Product Description
The integrated structural thermocouple and thermal resistance products with the function of temperature measurement and transmission can be realized by putting the two wire system modules of transmitter into the connection box of the thermocouple and thermal resistance products,such as normal packaged type,explosion proof type and sheathed type,the integration production can be used to measure the temperature of liquid,gas or steam medium directly.It receives the input signals of the thermocouple and thermal resistance with standard graduation mark and generates the linear 4-20mA DC by the measured temperature.The temperature are measured and controlled by the contact of the DC output signal and computer system.This temperature transmitter can be widely used to the scientific research field of the industrial sectors, such as electric power, metallurgy, petroleum, chemical engineering, aviation, mechanics, light industry, textile, medicine, food and national defense.
