The Baratron® D28F 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 D28F provides accurate, reliable, and repeatable pressure measurements for multi-step processes. The D28F is temperature controlled at 100°C, and is available in full scale ranges of 1, 10, 100 and 1000 Torr, with a customer specified second output having either a 2, 5, or 10 times lower full scale pressure output to provide a proportionally higher sensitivity. The lower pressure limitation of system A/D resolution is now minimized with higher output signal levels. The D28F requires ±15 VDC (±5%) input at 500 mA (max.), and provides two outputs of 0 to 10 VDC linear with pressure.

Based on the well-established Baratron capacitance manometer technology, the sensor's wetted surfaces are made of Inconel® for corrosion resistance and process compatibility. Measurements are independent of gas composition. 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


The modern stainless steel enclosure makes the D28F cleanroom-compatible. Its dual output makes the D28F ideal for multi-step processes.
