1F Piezo Diaphragm Vacuum Gauge

2-2108-001 and 2-2109-0XX

The Televac Piezo Diaphragm Gauge measures absolute pressures by determining the deflection of a diaphragm and measuring the formation of a strain gauge attached to the diaphragm. The response of the sensor does not depend on the gas type. The 1E and 1F piezo diaphragm sensors provide a wide range, fast response, and extremely stable measurement.

The Televac 1F Piezo Diaphragm Vacuum Sensor Features

  • Temperature-compensated, piezo-resistive pressure sensor provides excellent performance and long-term stability
  • Nickel-plated brass or stainless steel body
  • Various connection types available. (1/8” NPT, KF, CF) Solid-state reliability
  • Low power
  • Much lower price than capacitance diaphragm gauges with a wider range
