Features

Baratron® Capacitance Manometer Technology

Capacitance manometers are electro-mechanical gauges that can measure both pressure and vacuum. The capacitance gauge translates a pressure-modulated movement in a thin diaphragm into an electrical signal proportional to the pressure. The pressure sensor is the thin diaphragm that is exposed to the pressure or vacuum being measured via the inlet tube. An electrode is mounted in the reference cavity behind the diaphragm. Pressure differences between the process and the reference cavity deflect the diaphragm slightly, changing the distance between it and the electrode. Variations in this distance produce variations in the capacitance between the diaphragm and the electrode creating an electrical signal that is proportional to the pressure change. Since differences in the capacitance signal are produced by physical changes within the manometer and not by changes in the gas properties, pressure measurements by the capacitance manometer are independent of the composition of the gas being measured.

Gas independent absolute pressure measurement with a Baratron® capacitance manometer. Schematic shows the internal components and functional zones.

Percent of Reading Accuracy

Accuracy is specified as a percent of Reading, not Full Scale, as seen in some of the lower performance devices. Percent of Reading accuracy provides you with an even more accurate output signal in the lower scale of the pressure range, where it is needed most.

Differential Pressure Measurement

These capacitance manometers are referenced to local atmospheric pressure and measure the difference between the measurement side (Px) and the reference side (Pr) of the diaphragm. Applications include air and gas flow measurements for filters and analytical systems, downstream pressure control in thin film processing systems, and automated leak testing systems.

Inconel® and Incoloy® Construction Wetted Surfaces

These pressure transducers feature Inconel® and Incoloy® nickel alloy construction of the pressure sensor allowing it to operate without damage in virtually any chemical environment, including halogens, deionized water and steam, and ozone. The sensor is fully welded with no intermediate brazing or joining materials.

Wide Variety of Pressure Output Signals

These capacitance manometers are available in a wide variety of pressure output signals.  They can be used as a pressure transducer when choosing the 0-5 VDC or 0-10 VDC output option, or as a pressure transmitter when choosing the 4-20 mA output options.

Choice of Connector Types

These pressure transducers are available with a number of connectors for easy integration into a system.  Connector options include:

  • 9-pin male D-subminiature
  • 15-pin male high-density D-subminiature
  • 9-pin D-subminiature on flying lead
  • 4-pin Bendix PTO
  • Flying Leads – 6 ft (2 m)
  • Flying Lead with 15-pin male D-subminiature
