Dwyer 2020D-BUNA-IC Magnehelic Differential Pressure Gauge, buna-N, 0 to 20 inWC/0 to 5 kPa

Model: 2020D-BUNA-IC

Dwyer 2020D-BUNA-IC Magnehelic Differential Pressure Gauge, buna-N, 0 to 20 inWC/0 to 5 kPa

Model: 2020D-BUNA-IC

Work with simple and frictionless gauge movement with this differential pressure gauge that can indicate positive, negative, or differential pressure with 1% accuracy. In addition, this gauge features a dual scale, a measuring range of 0 to 20 inWC and 0 to 5 kPa, and a Buna-N diaphragm that allows use with hydrogen.

Features

  • Easy to read gauge through undistorted plastic face permits viewing from far away
  • Patented design provides quick response to pressure changes means no delay in assessing critical situations
  • Durable and rugged housing and high-quality components combine to provide long service life and minimized down-time
  • High accuracy option is twice as accurate as the standard gauge
  • Bezel provides flange for flush mounting in panel
  • Clear plastic face is highly resistant to breakage and provides undistorted viewing of pointer and scale
  • Precision litho-printed scale is accurate and easy to read
  • Red tipped pointer of heat treated aluminum tubing is easy to see and is rigidly mounted on the helix shaft
  • Pointer stops of molded rubber prevent pointer over-travel without damage
  • "Wishbone" assembly provides mounting for helix, helix bearings and pointer shaft
  • Jeweled bearings are shock-resistant mounted, provide virtually friction-free motion for helix, and are motion damped with high viscosity silicone fluid
  • Zero adjustment screw is conveniently located in the plastic cover, and is accessible without removing the cover
  • O-ring seal provides pressure tightness
  • Helix is precision made from an alloy of high magnetic permeability and mounted in jeweled bearings; it turns freely, following the magnetic field to move the pointer across the scale
  • Calibrated range spring is flat spring steel and reacts to pressure on diaphragm
  • Small amplitude of motion assures consistency and long life and live length is adjustable for calibration
  • Silicone rubber diaphragm with integrally molded O-ring is supported by front and rear plates and is locked and sealed in position with a sealing plate and retaining ring
  • Diaphragm motion is restricted to prevent damage due to overpressures
  • Die cast aluminum case is precision made and iridite-dipped to withstand 168 hour
  • Overpressure protection
  • O-ring seal for cover assures pressure integrity of case
  • Samarium Cobalt magnet mounted at one end of range spring rotates helix without mechanical linkages

Applications

  • Filter monitoring
  • Air velocity
  • Blower vacuum monitoring
  • Fan pressure indication
  • Duct, room or building pressures
  • Clean room positive pressure indication
