Applications
NPSH 4-22 psia 4-20mA filtration pump suction port pressure sensor for water treatment - An absolute pressure sensor for water treatment pump chamber use to measure filtration pump NPSH pressure of freshwater over a range of 4 to 22 psi abs from the G1/4 male process connection, and sending the corresponding 4-20mA signal through the submersible cable electrical connection.
Vacuum insulation 15 psi absolute range millivolt output pressure sensor for air extraction use - An absolute pressure sensor for vacuum insulation air extraction use to measure vacuum pressure of air over a range of 0 to 15 psi abs from the G1/4 male process connection, and sending the corresponding mV/V signal through the submersible cable electrical connection.
10 metre range non-vented submersible absolute range pressure and barometric sensor - we need to measure water level from 0 to 10 metres with a submersible pressure sensor, but we are going to have difficulty in getting some of the sensors vented to atmosphere pressure.
2 bar absolute range 4 -20 mA output submersible silicon diaphragm liquid level sensor - Low cost stainless steel 316L submersible liquid level sensor with silicon strain gauge technology for measuring over a 2 bar absolute hydrostatic pressure range and sending out a 4 to 20 milliamps signal.
