D25F Baratron® Heated Dual-Range Absolute Capacitance Manometer
(1-1000 Torr), Temperature Controlled to 100°C, with Trip Points
Direct, Absolute, Analog Pressure/Vacuum Measurement
The Baratron® D25F Dual-range Manometer, an application-specific absolute capacitance manometer, is the latest addition to the MKS family of general purpose manometers. With two distinct measurement outputs, the D25F provides accurate, reliable, and repeatable pressure measurements for multi-step processes. The D25F is temperature controlled at 100°C, and is available in full scale ranges of 10, 100 and 1000 Torr, with a customer specified second output at 2, 5, or 10 times lower full scale. The lower pressure limitation of system A/D resolution is now minimized with higher output signal levels. The instrument operates with ±15 VDC (±5%) input at 600 mA (max.), and provides two outputs of 0 to 10 VDC linear with pressure.
The D25F's sensor exposes only Inconel® to the process permitting the use with corrosive or dirty gases. Measurements are independent of gas composition. The D25F also features two trip point relays, each separately adjustable from 0.1 to 100% of Full Scale. Dual color LEDs indicate relay status. Typical relay uses include pump cross-over and valve activation. The modern stainless steel enclosure provides a cleanroom compatible product.
