Item Description:
The temperature transmitter of this series of temperature transmitters is installed on the spot. It uses a two wire transmission mode (two wires as a power supply input and a common transmission line for signal output), and transforms the thermocouple and the thermal resistance signal into the output signal of 4-20mA which is linear with the input signal or the measured temperature. The transmitter can be installed in a thermocouple and thermoelectric resistance junction box to form an integrated structure. As a generation of temperature measuring instruments, it can be widely used in power, light industry, prevention, food, national defense and scientific research.
This temperature transmitter can convert the temperature from -100 Celsius to 100 Celsius to the 4-20mA output signal.
2. Features:
2. The 4-20mA signal is directly output in the field installation and the junction box of the thermal resistance and thermocouple.
3. High precision and low power consumption. The use of ambient temperature range is wide, and the work is stable and reliable.
4. The range is adjustable and has a linear correction function. The thermocouple temperature transmitter has the function of automatic compensation for cold end.
