The Dwyer Instruments 4001B Capsuhelic Differential Pressure Gauge delivers reliable, precise measurement of differential pressures in demanding industrial environments. Built on the proven Magnehelic design, this gauge features a frictionless movement that ensures accurate readings even at full-scale ranges as low as 0.5 in H2O. The 4001B model offers a 0-1 in H2O range and is housed in a durable brass case, making it suitable for a wide variety of applications.
Key Features & Highlights
- High System Pressure Capability: Measures differentials as low as 0.1 in H2O while withstanding system pressures up to 500 psig.
- Frictionless Movement: Provides fast, accurate response and long-term reliability.
- Diaphragm-Actuated Design: No filling liquid required, allowing outdoor use without limitations.
- External Adjustments: Zero and range adjustments can be made from outside the gauge, eliminating the need for disassembly during normal service.
- Versatile Applications: Suitable for measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks, and more.
- Optional Hydrogen Compatibility: Can be used with hydrogen when ordered with a Buna-N diaphragm (pressures must be less than 35 psi).
Applications
The Dwyer 4001B is ideal for HVAC, filtration monitoring, liquid level measurement, and general industrial pressure monitoring. Its robust construction and high system pressure rating make it a dependable choice for both process and plant maintenance applications.
