HM8250B CNG differential pressure sensor

HM8250B High temperature and low temperature durable Pressure Range 20~250kPaA & 20~400kPaA Vss:5VDC,Vout:0.2~4.8VDC

Applying the technology of MEMS and Application Specific Integrated Circuit (ASIC), HM8250 Series 

Twinchannel absolute pressure sensor (differential pressure sensor) can offer two groups of individual 

absolute pressure signal detection and individual output. When the two groups of pressure range 

have the same value, it can be used for differential pressure measurement. Both of the two groups of 

pressure range and be used for the individual detection of atmospheric pressure and gas pressure. 

This product is characterized with power sharing, space saving and easy installation.
