pressure sensor working principle

industrial pressure sensor suppliers

the pressure transmitter is small in size, easy to install, and is insulated by a stainless steel case. It is suitable for measuring gas and liquid media compatible with the material of the contact part. It can be used to measure gauge pressure, negative pressure, and absolute pressure.

The hygienic (flush film) pressure transmitter is formed on the basis of the prototype of the universal pressure transmitter and is equipped with a welded sealing diaphragm structure. It's welded sealing isolating diaphragm device has a variety of different process connection structures, which are especially suitable for pressure measurement in high temperature, high viscosity, crystalline medium and easy to block, and also suitable for pressure measurement in sanitary and medical applications.


pressure transmitter function

1.Reverse polarity protection and transient over-current and over-voltage protection to meet EMI protection requirements.

2. Using laser-regulated temperature compensation process, the measured value is more stable.

3. Wide range coverage, -0.1~100MPa optional.

4.Automatic temperature compensation, automatic temperature correction.

5.Strong overload and anti-interference ability, economical and practical.

6.Compact structure and easy installation.
