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 is a RoHS (Restriction of Hazardous Substances) compliant version of the latest MKS family of general purpose capacitance manometers. It 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.
