Low Pressure Transducer Model PR 274/275
The PR-274-275 incorporates a new micro-machined glass-on-silicon (G1-Si) capacitance sensor. This technology revolutionizes very low pressure measurement. Temperature related zero drift, calibration shift due to overpressure, non-repeatability, non-linearity, and extremely low pressure sensitivity have been some of the problems which have plagued the controls industry.
• 100% solid state, micro-machined, glass-on-silicon, ultra-stable capacitance sensor • As low as ±0.05” we (± 12.5 pa)
• Can resolve less than 0.00001” we (0.00025 pa) • Up to 10 PSID overpressure without zero shift • Up to 6 field selectable ranges in one unit • Wide 12-40 VDC/12-35 VAC unregulated supply voltage
