Low Pressure Sensor,

PR-274 Series Information

  • 100% Solid‑State, Micro‑Machined, Glass‑on‑Silicon, Ultra‑Stable Capacitance Sensor
  • Non‑Interacting Zero and Span Trimmers
  • NIST Traceable Calibration
The PR‑274 incorporates a new micro‑machined glass‑on‑silicon (Gl‑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.
