Product Description China 4-20ma Digital Diffused Silicon Air Oil Pressure Transmitter
It is made of imported piezoresistive diffused silicon, with reverse polarity and current limiting protection; laser adjustment temperature compensation; strong overload and anti-interference ability, high sensitivity, small temperature drift and good long-term temperature performance. The compact pressure transmitter is small in size, easy to install, and uses a stainless steel shell to isolate and prevent corrosion. It is suitable for measuring gas and liquid media that are compatible with the material of the contact part. It can be used to measure gauge pressure, negative pressure and absolute pressure. Stable and durable structure, high precision and anti-interference, a variety of electrical connections are optional
