Integrated temperature transmitter


The integrated temperature transmitter is a new type of temperature measuring instrument with ultra-small size, excellent performance and high precision. It has the characteristics of small size, light weight, convenient installation and installation, and can be directly installed in the junction box of general industrial thermal resistance and thermocouple, and forms an integrated structure with the field sensing components. This not only saves more expensive compensation wires and cables, but also reduces signal transmission distortion and interference, resulting in highly accurate measurements.

The transmitter can be used with a variety of regulators, especially for multi-channel data acquisition, measurement and control. It is used with the intelligent industrial signal detector produced by our company to form a multi-channel temperature cycle detection system in the control room.

At present, the product is widely used in petroleum, chemical, power plants, breweries, medicine, cement, textile, food, environmental monitoring, boilers, rubber and other industrial fields.

Integrated temperature transmitter

First, the working principle:

Work with the measurement principle of hydrostatic pressure. The transmitter works with the measurement principle of hydrostatic pressure. It generally uses a silicon pressure load cell sensor to convert the measured pressure into an electrical signal, and then is amplified by an amplifier circuit and compensated by a circuit, then amplified by an amplifier circuit and compensated by a circuit, and finally output with a 4-20 mA DC electrical signal.

The integrated temperature transmitter can have an actual vacuum, but is adjusted at the circuit processing stage to obtain absolute pressure. The gauge pressure measurement transmitter is measured relative to atmospheric pressure and is equivalent to the P2 reference atmospheric pressure reference atmospheric pressure P0. Relative to atmospheric pressure measurement, equivalent to reference atmospheric pressure. This is the case for most pressure measurements on site, such as main steam pressure measurements. This is the measurement, such as main steam pressure measurement. Differential Pressure Measurement Transmitter Differential pressure measurement transmitters are mainly divided into liquid level measurement and flow measurement. Differential pressure measurement transmitters are mainly divided into liquid level measurement and flow measurement.

The extension of the integrated 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. Based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid, the advanced foreign isolation type is adopted. Diffused silicon sensitive component or ceramic capacitor pressure sensitive sensor converts static pressure into electrical signal, diffused silicon sensitive component or ceramic capacitor pressure sensitive sensor, converts static pressure into electrical signal, and then converts into standard electricity through temperature compensation and linear correction signal.

The integrated temperature transmitter converts this tiny change in capacitance into a standard current (or voltage) output through a balancing circuit, resulting in a current (or voltage) signal that is linearly related to the pressure change. The output is such that a current (or voltage) signal that is linearly related to the change in pressure is obtained. The working principle of inductive transformers is similar.

Note: If the input distance is far away and the accuracy is affected, several types of temperature transmitters can be made into a three-wire input connection without connecting the compensation wire, thereby reducing the error and improving the accuracy, and also selecting the intelligent transmission. The device achieves the purpose of measurement.
