In numerous fields of industrial production, accurate measurement of the pressure of liquids and gases is crucial for ensuring production safety and efficiency. The PM100 series pressure transmitter launched by Shanghai Zanke Automation Co., Ltd., with its excellent performance and wide applicability, has become an ideal option in the field of industrial pressure measurement.

Core Principles and Structural Advantages

The core of the PM100 series pressure transmitter lies in its pressure sensor with an isolation diaphragm. This component has undergone computer automatic detection and laser trimming processes, achieving zero point and sensitivity temperature compensation within a wide temperature range, thus ensuring measurement stability.

When the pressure of the measured medium acts on the sensor diaphragm, the diaphragm produces a tiny displacement proportional to the pressure. After the electronic circuit captures this displacement, it converts it into a standard industrial measurement signal. Its structural design has significant highlights:

• The adoption of application-specific integrated circuits and surface mounting technology improves the integration and reliability of the device.

• The robust metal housing can adapt to various harsh working environments, and the 316L stainless steel isolation diaphragm ensures corrosion resistance to different media.

• Multiple display units are available for selection to meet reading needs in different scenarios.

Wide Range of Application Scenarios

The PM100 series pressure transmitter has a very wide range of applications. It can measure various liquids and gases and play an important role in many industrial fields such as petroleum, chemical industry, electric power, metallurgy, pharmaceuticals, and food. Whether it is a high-temperature and high-pressure chemical reaction kettle or a precision food processing pipeline, it can stably and reliably provide pressure data.
