Details
The Dwyer Capsuhelic® Differential Pressure Gauge is a precision instrument designed to measure flowing fluids, pressure drop across filters, liquid levels in storage tanks, and a range of other applications involving pressure, vacuum, or differential pressure. Built around a simple, frictionless movement, this differential pressure gauge delivers dependable full-scale readings even at very low ranges, making it a reliable choice for facilities that depend on accurate monitoring.
Key Features:
- Low-Range Accuracy: Frictionless movement permits full-scale readings as low as 0.5" water column
- High-Pressure Capability: Measured pressure is held within an integral capsule, allowing use on system pressures up to 500 psig, even when reading differentials below 0.1 in. w.c.
- No Filling Liquid Required: Diaphragm-actuated design avoids filling liquids that could restrict outdoor use
- Easy Field Adjustment: Zero and range adjustments are made from outside the gauge, with no disassembly needed for normal service
- Hydrogen Compatible: Suitable for use with hydrogen at pressures below 35 psi
- Optional Forged Brass Housing: Required for use with water or water-based fluids
- Complete Mounting Kit Included: Comes with (1) Capsuhelic® differential pressure gauge, (2) 1/4" NPT plugs for duplicate pressure taps, (4) flush mounting adapters with screws, and (4) surface mounting screws
Ideal For:
- Monitoring pressure drop across filters in HVAC and industrial filtration systems
- Tracking liquid levels in storage tanks
- Facilities requiring accurate readings across a wide range of system pressures
- Outdoor or unconditioned installations where filling-liquid gauges are impractical
Frequently Asked Questions:
Q: What is the maximum system pressure this gauge can handle?
It can be used on system pressures up to 500 psig, even when the differential being measured is less than 0.1 in. w.c.
Q: Does this gauge need to be filled with liquid to operate?
No. It uses a diaphragm-actuated design that requires no filling liquid, which also makes it better suited to outdoor applications.
Q: Can this gauge be used with hydrogen?
Yes, it can be used with hydrogen at pressures less than 35 psi.
Q: What's included with the gauge?
Each unit includes the Capsuhelic® differential pressure gauge, two 1/4" NPT plugs for duplicate pressure taps, four flush mounting adapters with screws, and four surface mounting screws.
