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.

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.

Absolute Pressure Measurement

These Baratron® pressure transducers are referenced to vacuum for absolute pressure measurement. Applications include: vacuum furnaces, freeze-drying of fruits and vegetables, gas lasers, automotive component testing, bottle coatings, and vacuum distillation.

Inconel® and Incoloy® Construction

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.

0 to 10 VDC Proportional Analog Output

These Baratron® capacitance manometers feature a high-level 0-10 VDC analog output signal that is linear with pressure. This analog output can be interfaced with an MKS pressure controller, an MKS power supply/display instrument, or any instrument that meets these requirements. They are powered by a ±15 VDC input voltage.

Two Adjustable Process Trip Point Relays

The 623F Absolute Capacitance Manometer features two user adjustable process trip point relays, each with an adjustment range from 0.1% to 100% of Full Scale or voltage equivalent 0.01 to 10 VDC. Dual color LEDs indicate relay status. Typical relay uses include pump cross-over and valve activation.
