All Sensors Corp., Morgan Hill, CA, offers a 1/2 in.H₂O F.S. millivolt output pressure sensor offered as a PCB-mountable package with 2 pressure ports. Seven pressure ranges are available from 1/2 in.H₂O F.S. to 30 in. H₂O F.S.; dead volume to each pressure port is matched for improved common mode response. The sensors' millivolt output is proportional to either gauge or differential pressure. Output offset errors are reduced by electrical cross-coupling compensation used within the sensor. Position sensitivity is greatly reduced by the company's CoBeam² technology. Applications include medical breathing systems for lung function, respiratory monitoring, sleep diagnostics, and drug delivery; HVAC; and process automation.
