Descrizione

The PX291 Series of differential pressure transmitters is designed to measure low pressures while using little power. A selection of ranges is available to meet most industrial and laboratory applications. The transmitters are housed in a flame-retardant, glass-reinforced polyphenylene oxide case. Electrical connections are made by means of a 3.8" terminal with #6 screws. There are no moving parts and the transducers are virtually position insensitive. The span and zero settings are made via 20-turn potentiometers, for easy and precise adjustments. The pressure sensing element is a differential capacitive cell for the low pressure ranges from 0.1 to 5 inH2O and a piezoresistive chip for ranges above 5 inH2O. Both sensors ensure reliability and long-term stability.

OFFSET OPTIONS
If the measured differential pressure is expected to go from positive to negative, a transducer with offset (elevated zero) should be ordered. The standard models in the order chart have no offset (i.e., at zero differential pressure, the output is 0 Vdc or 4 mA). 2 offset options are available: gAh 1.4 Span Offset At zero differential pressure, the output is 1.25 Vdc or 8 mA
Allowable pressure excursion: -33% to 100% of range gBh 1.2 Span Offset At zero differential pressure, the output is 2.5 Vdc or 12 mA
Allowable pressure excursion: -100% to 100% of range
Examples: PX291-001WD5V-A will have a range of 1"
