Differential capacitance manometers can be connected to any pressure or vacuum source for use as the reference pressure. These manometers read the difference in pressure between the inlet tube and the reference cavity at the backside of the electrode. Differential pressure transducers can be used to measure either the true differential pressure or vacuum between two locations, or the reference side of the product can be left open to provide a true reference to local atmospheric pressure. 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.
The patented capacitance sensor is built entirely from Inconel® nickel alloys on its measurement side, which offers superior corrosion resistance over long periods of time. Inconel® construction also offers high overpressure tolerances that reduce errors due to line pressure spikes, and high burst pressure ratings that contribute to overall system safety.
Three (3) different analog output signals (0-1 VDC, 0-5 VDC, and 0-10 VDC) are included for use in nearly any control or data acquisition system.
These Baratron® differential capacitance manometers can be equipped with any of twelve (12) different fittings on either the measurement or reference sides, including common industrial and semiconductor-industry standards like VCR®, NW-KF, VCO®, and NPT.
Two (2) independently-adjustable trip relays are included for control of external equipment and components based on a pressure trip point. The trip points are adjustable from -100% to +100% of the full-scale measurement range. The DPDT relay contacts are rated at 1.0 amp at 30 VDC or 0.3 amp at 120 VAC.
