The integrated temperature transmitter is a commonly used transmitter product. It is a replacement product for temperature measurement and control in modern industrial sites and research institutes. The product has the advantages of stable performance, flexible use, high reliability, and easy maintenance. Today we mainly introduce the working principle of the integrated temperature transmitter, hoping to help users better use the product.
Integrated temperature transmitter works
The integrated temperature transmitter works on the principle of hydrostatic pressure measurement. The transmitter works on the principle of hydrostatic pressure measurement. It generally selects the silicon pressure measuring transducer to convert the measured pressure into electrical signals, and then compensates by the amplification circuit and the compensation circuit, and then compensates by the amplification circuit and the compensation circuit. Finally, the 4-20 mA DC electrical signal is output.
The integrated temperature transmitter can have an actual vacuum but is adjusted at the circuit processing stage to obtain absolute pressure. The gauge pressure transmitter is measured relative to atmospheric pressure and is equivalent to P2 reference atmospheric pressure reference atmospheric pressure P0. Relative to the atmospheric pressure measurement, it is equivalent to the reference atmospheric pressure. This is the case for most pressure measurements in the field, such as main steam pressure measurements. This is the case for measurements, such as main steam pressure measurements. Differential Pressure Measurement Transmitter Differential pressure measurement transmitter is mainly divided into liquid level measurement and flow measurement. Differential pressure transmitters are mainly classified into liquid level measurement and flow measurement.
The extended temperature transmitter understands that the liquid level sensor is based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid, and based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid, the foreign advanced isolation type is adopted. Diffused silicon sensitive element or ceramic capacitive pressure sensitive sensor converts static pressure into electrical signal, silicon-dispersion sensitive element or ceramic capacitive pressure-sensitive sensor, converts static pressure into electrical signal, and then converts into standard electricity through temperature compensation and linearity correction signal.
The integrated temperature transmitter converts this tiny capacitance change into a standard current (or voltage) output through a balancing circuit, so that a current (or voltage) signal that is linearly related to the pressure change is obtained. The output is thus a current (or voltage) signal that is linearly related to the pressure change. The working principle of inductive transformer is similar.
