Working principle of integrated temperature transmitter

The integrated temperature transmitter is an updated product for temperature measurement and control in modern industrial sites and scientific research institutes. It is an essential product for distributed systems and digital bus systems. Users need to master product application knowledge when using integrated temperature transmitter products. Today, the editor mainly introduces the working principle of the integrated temperature transmitter to everyone, hoping to help everyone.

Working principle of integrated temperature transmitter

The integrated temperature transmitter works on the principle of measuring liquid static pressure. The transmitter works on the principle of measuring liquid static pressure. It generally uses a silicon pressure sensor to convert the measured pressure into an electrical signal, which is then amplified by an amplifier circuit and compensated by a compensation circuit, and finally output as a 4~20mA DC electrical signal.

The integrated temperature transmitter can have an actual vacuum, but it is adjusted in the circuit processing link to obtain absolute pressure. The gauge pressure measurement transmitter measures relative to atmospheric pressure, which is equivalent to P2 reference atmospheric pressure reference atmospheric pressure P0. Relative to atmospheric pressure measurement, it is equivalent to reference atmospheric pressure. Most of the pressure measurements on site are in this case, such as main steam pressure measurement. This is the case with measurement, such as main steam pressure measurement. Differential pressure measurement transmitter Differential pressure measurement transmitter is mainly divided into liquid level measurement and flow measurement. Differential pressure measurement transmitter is mainly divided into liquid level measurement and flow measurement.

Extended understanding of integrated temperature transmitter Liquid level sensor is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses foreign advanced isolated diffused silicon sensitive elements or ceramic capacitor pressure sensitive sensors to convert static pressure into electrical signals, and then converts it into standard electrical signals after temperature compensation and linear correction.

The integrated temperature transmitter converts this tiny capacitance change into a standard current (or voltage) output through a balanced circuit, thereby obtaining a current (or voltage) signal output in a linear relationship with the pressure change. Output, thereby obtaining a current (or voltage) signal output in a linear relationship with the pressure change. The working principle of the inductive transformer is similar.
