HPT701 Air Differential Pressure Sensor
Air Differential Pressure Sensor is precision engineered for monitoring differential pressure of air and compatible gases in commercial and OEM applications and liquids with 0.25% accuracy.
Application :
● HAVC Air differential pressure
● Wind pipe pressure measurement
● Industrial dust removal equipment
● Purification plant
● Blow down expander
● Leak detection device
Advantages
01It has a built-in high-sensitivity air pressure sensing element independently developed by HOLYKELL, which can measure air pressure of 1 pa.
02The sensor comes with digital temperature compensation, which can be used in environments with high and low temperature differential pressure.
03It adopts moisture-proof, waterproof, dust-proof and other technologies, and can be used in bad weather or complex working conditions.
04CE certification.
