Product features:
- High accuracy and good reliability. In-built anti-interference board
- Provided with backlight and three-key function for site display and adjustment
- Two-wire system standard 4～20mA signal output. Superposed digital signal
- The digital signal conforms to Bell202 standard HART agreement and it only needs a load resistance and a hand terminal to realize on-line adjustment. The operation is extremely convenient.
Field of application:
It can be used to measure the gauge pressure, absolute pressure and negative pressure of corrosive gases, liquids and steam in the fields of petroleum, chemical industry, metallurgy, electric power and environmental protection. It can also be used to measure the pressure under low vacuum, atmospheric pressure and harsh environment.
