Product Description

This product is widely used in enterprises and institutions such as petroleum, ocean, reservoir, river, chemical, metallurgy, electric power, scientific research, etc. to measure fluid pressure, and is suitable for all occasions, all-weather environments and various corrosive fluids.

Características del producto

1. High accuracy and good stability. In addition to the imported original sensor being corrected by laser, the comprehensive temperature drift and nonlinearity of the whole machine within the use temperature range are finely compensated, so the nonlinearity is small and the temperature stability is good.
2. Reliable mechanical protection IP65 and explosion-proof protection iaⅡCT5, can be used in various harsh environments.
3. Can be used to measure viscous, crystalline and corrosive media.
4. 4~20mA DC standard current signal output, two-wire operation, strong anti-interference ability with load.
5. Small size, light weight, easy to install, debug, maintain and use.

Working principle

The process pressure converts the pressure signal into an electrical signal, which is amplified by the differential amplifier and the output amplifier, and then converted by the V/A converter to a 4~20mA standard current output signal that is linearly corresponding to the input pressure.
