Descrição

The OMEGA™ PX1000 Sputtered Thin Film Transducer is noted for high accuracy and excellent long-term stablility and reliability. Performance stability is ±0.1% for any combination of constant pressure and temperature within the operating range. The thermal error band performance is typically better than 0.25% within any 50°F temperature band. Highly stable sensing elements are achieved by sputtered film deposition which–coupled with advanced structural design– create tranducers with maximum, combined nonlinearity, hysteresis and nonrepeatability error of 0.25% FSO. Available in many standard ranges from 15 psi to 10,000 psi, the basic design of the PX1000 features all welded construction with proven strain isolation. The PX1000 sputtered gage pressure tranducers are manufactured in accordance with the program quality requirements of MIL-Q-9858A
