Description:
CJBP-ID uses piezoresistive differential pressure sensor as sensing element. Silicon oil is filled in between die and two diaphragms, when measured differential pressure is added on two diaphragm, the pressure could be transferred onto die through silicon oil. Sensor die connects with amplifier circuit through wires, using semi-conductor’s piezoresistive effect, transforming differential pressure signal into electric signal.
Features:
Full stainless steel construction, compact size, easy installation
Laser welding, full-sealed construction; protection IP65
Using piezoresistive differential pressure sensor, 316L isolated diaphragm
Temperature compensation and aging, stable performance
Zero and span adjustable outside
Application:
Measure temperature of gas or liquid which is compatible to 316L stainless steel
Used for differential pressure measurement of petroleum, chemi-industry, power station and hydrology,etc.

Ordering note
1. Media must compatible with
wetted parts.
2. To ensure the products can
working reliable, we suggest that customer install three valve group between
measure point and transmitter that can assure media flow to positive &
negative cavity slowly and uniformly.
3. Suggest to put two pressure
port as the same level when install so as to minimize the position influence.
4. Special requirement ,such as
strong shock, moment vibration, strong electromagnetism, radio frequency
interference ,please consult us.
