Series 646
Differential Pressure Transmitter
Ranges from 0 to 0.25" w.c., Overpressure Protection to 10 psig, ±1% Accuracy
 
Low cost Series 646 Pressure Transducer is designed for use with air and inert gases and can accurately measure differential pressure down to ±0.5" w.c. The transducer utilizes a fast response capacitive sensor and is temperature compensated for stable output. Units provide an amplified voltage output signal ideal for VAV systems, filter monitoring, HVAC fan control, building pressurization and leak detection systems.
