6301B Hesman Connector Temperature Transmitter Product Description
The 6301B temperature transmitter combines a temperature sensing element (thermistor) with a signal conversion amplification unit to measure the temperature of liquids, vapors, and other gas media within the range of -200 ° C to 500 ° C in various process flows. It can be used in conjunction with display instruments, recording instruments, and various control systems. It has the characteristics of simple structure, easy installation and use. Currently widely used in industries such as petrochemicals, metallurgy, and power plants.

6301B Hessman joint type temperature transmitter
Working principle of 6301B Hirschman joint type temperature transmitter
The temperature transmitter consists of a temperature sensor and a signal converter. The signal converter is installed in the cold junction box of the temperature sensor. The temperature sensor is affected by temperature and produces resistance or potential effects, which are converted into a differential voltage signal. This signal is amplified by an amplifier and then converted into a 4-20mA current signal corresponding to the measurement range through voltage and current conversion
Characteristics of 6301B Hirschman joint type temperature transmitter
Two wire transmission, where the two wires powered by the signal converter also transmit the output signal simultaneously
Output constant current signal (4-20mA) with strong anti-interference ability and good remote transmission performance
The signal converter is encapsulated in epoxy resin as a module, which has the advantages of vibration resistance, corrosion resistance, moisture resistance, etc. Can be used for working conditions with poor environmental conditions
The millivolt signal of the thermocouple is directly converted into a 4-20mA current output through a signal converter, and the signal is transmitted using ordinary cables, which can save expensive compensation wires.
The temperature transmitter with on-site display can output 4-20mA current signals and read values at the temperature measurement site, making it convenient to use
High precision, anti-interference, good long-term temperature performance, maintenance free, and capable of remote transmission (up to 1000 meters)
