Dwyer Capsuhelic® 4000 Series Differential Pressure Gauge

Dwyer Capsuhelic gauges are ideal for measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and other applications involving pressure, vacuum or differential pressure.

Using simple, frictionless Magnehelic movement, the gauge quickly indicates low air or non-corrosive gas pressures: positive, negative, or differential. The design resists shock, vibration, and overpressure, and has no manometer fluid to evaporate, freeze, or cause toxic or leveling problems.

Key Specifications

  • Air and compatible gases and oil- or water-based liquids
  • For system pressures of up to 500 psig, even when differentials are less than 0.1" WC
  • Accuracy: ±3% full scale (±2% on 4000S models and ±4% on 4200, 4210, 4215, 4220, 4300, 4400, and 4500 models)
  • 1/4" NPTF high and low pressure taps (one pair on top for air and gas, one pair on bottom for liquids)
  • Available in PSI, inches water column, and kiloPascals
