Temperature Transmitter Principles and Features

Lead: The temperature transmitter is a meter that converts a temperature variable into a standard output signal that can be transmitted. It is mainly used for the measurement and control of industrial process temperature parameters. It can convert a physical measurement signal or an ordinary electrical signal into a standard electrical signal output or a device that can be output by a communication protocol. It is mainly used for the measurement and control of industrial process temperature parameters.

The temperature current transducer converts the signal of the temperature sensor into a current signal, which is connected to the secondary appearance and then shows the corresponding temperature. For example, the letter Ruida szxrdt series temperature sensor model is PT100, then the effect of the temperature and current transmitter is to convert the resistance signal into a current signal, enter the appearance, show the temperature.

The temperature sensor's temperature effect produces a resistance or potential effect, which is converted to produce a differential voltage signal. This signal is amplified by an amplifier and then converted by voltage and current to output a 4-20 mA current signal corresponding to the range.
