Pressure Transmitter 4-20ma

Pressure Transmitter 4-20ma

The pressure transmitter 4-20ma uses a high-performance pressure-sensitive chip that combines advanced circuit processing and temperature compensation techniques to convert pressure changes into linear current or voltage signals. The product 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 4-20ma is formed on the basis of the prototype of the universal pressure transmitter and is equipped with a welded sealing diaphragm structure. Its 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
