MKS Baratron® D25F Dual-Range Manometer is a RoHS-compliant applications specific absolute capacitance manometer based on the latest MKS family of general purpose manometers. It features the added capability of providing two distinct measurement outputs to provide 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.

Features & Benefits:

  • Second output provides greater resolution over lower ranges
  • Percent of Reading accuracy for repeatable output
  • Measures total pressure directly, independent of gas composition
  • Integrated sump for particle protection
  • High overpressure rating for reliability
  • All Inconel® sensor and wetted surfaces for corrosion resistance

Applications:

Typical relay uses include pump cross-over and valve activation. The modern stainless steel enclosure makes the D25F cleanroom-compatible. Its dual output also makes the D25F ideal for multi-step processes.
