HUBA
696/697 Series Differential Pressure Transmitter
3-Wire, Voltage Output, F.S. Ranges 1.2 to 12“ w.c.
DESCRIPTION
Type 696/697 differential pressure transmitters incorporate proven Ceramic sensor technology and have a calibrated, temperature-compensated voltage signal output. They are designed for OEM applications and have pin connections for printed circuit board mounting.
They are ideally suitable for monitoring airflows and differential pressures in air conditioning systems as well as differential pressure relationships in medical, environmental and other applications that require low differential pressure measurement.
