The temperature transmitter uses the thermocouple and thermal resistance as the temperature measurement element, from the output signal of the temperature measurement element to the transmitter module.After the circuit processing of the protection, the 4-20mA current signal output is converted into a linear relationship with temperature.

Temperature transmitter model
Most of the warehouses of general storage items are wall -mounted temperature and humidity sensors. The optional temperature and humidity sensors are: JCJ100ND digital temperature humidity sensor, JCJ175A digital temperature humidity sensor, wireless temperature humidity sensor, JCJ103 wireless temperature humidity sensor.
Temperature transmitter working principle
The thermocouple or the thermal resistance sensor converts the test temperature into a electrical signal, and then the signal is sent to the input network of the transmitter. The network contains zero -and thermocouple compensation such as compensation.After zero, the signal input to the computing amplifier for signal amplification. The magnified signal is output with a 4-20mA DC current after being calculated by the V/i converter;There are two linear circuits of the transmitter, both of which are feedback.The thermal resistance sensor is corrected with a positive feedback method, and the thermocouple sensor is corrected with multiple segments.There are two display methods for integrated digital display temperature transmitters.The temperature transmitter displayed by the LCD outputs the two -line system, and the temperature transmitter displayed by the LED display is output.
