Overview of integrated on-site display temperature transmitter:

On site display is one of the types of integrated temperature transmitters.

Integrated temperature transmitterThe temperature sensor and temperature transmitter are integrated, and the temperature transmitter is placed in the junction box of the temperature sensor (thermistor, thermocouple) to convert the temperature into a 4-20mADC standard signal proportional to the output of the thermistor and thermocouple, which is transmitted to the secondary instrument and computer system to achieve accurate temperature measurement and control. The product is widely used in industries such as power, chemical, petroleum, food, medicine, and environmental protection. Integrated on-site display temperature transmitter/transmitter series

Working principle of integrated temperature transmitter

The change in thermoelectric potential (resistance) measured by a thermocouple (resistor) in working condition, throughIntegrated temperature transmitterThe bridge generates an unbalanced signal, which is amplified and converted into a 4-20mA electrical signal for the working instrument to display the corresponding temperature value. Output 4-20mA, strong anti-interference ability; Save compensation wires and install temperature transmitters. Integrated on-site display temperature transmitter/transmitter series

Integrated temperature transmitter product features
