Product Description

BP93420D-I Aluminium case Differential Pressure Transmitter for Air test


Introduction of mini differential pressure transmitter :


BP93420D-I is a kind of micro-differential pressure transmitter sensor, which uses the piezoresistive effect of semiconductor silicon material to convert the pressure difference between the two ends into the variable electrical signal required by the customer. For example, 4-20mA 0-10VDC. It is mainly used to measure the pressure difference of non-corrosive dry gas. It is widely used in the process control of boiler air supply, electric power, underground mine ventilation, micro-pressure automatic detection in ultra-clean workshop and other industries.Widely used in petroleum, chemical industry, metallurgy,electric power, textile, environmental protection, etc.

Ordering note

  • Media must compatible with wetted parts.
  • 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.
  • Suggest to put two pressure port as the same level when install so as to minimize the position influence.
  • Special requirement ,such as strong shock, moment vibration, strong electromagnetism, radio frequency interference ,please consult us.
