623F Baratron® Absolute Capacitance Manometer
(10-1000 Torr) with Trip Points
Direct, Absolute, Analog Pressure/Vacuum Measurement - Ambient Temperature Operation
The MKS 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. The 623F is an ambient temperature transducer, and is available in Full Scale ranges of 10, 20, 100, 500, and 1000 Torr. The instrument operates with ±15 VDC (±5%) input at <100 mA, and provides an output of 0 to 10 VDC linear with pressure. The 623F's sensor exposes only Inconel® to the process permitting the use with corrosive or dirty gases. Measurements are independent of gas composition.
