Arbetsprincip för integrerad temperatursändare

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 alla .

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 Sändare är huvudsakligen uppdelad i mätning av vätskenivå och flödesmätning .

Utökad förståelse av integrerad temperatursändare vätskenivås sensor är baserad på principen att det uppmätta vätskestatiska trycket är proportionellt mot höjden på vätskan . Den använder främmande avancerade isolerade diffus kiselkänsliga element eller keramiska kapacitorens känsliga sensorer för att konvertera statisk tryck till elektriska signaler och omvandlar sedan det till standardteckenkompensation och linjekompensation})

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 liknande .
