Capsuhelic? Differential Pressure Gage,0-0.5"w.c.

 

Differential pressure Gage, Range 0-0.5" w.c., for Vertical Scale Position Only.

 

The Capsuhelic gage is designed to give fast, accurate indication of differential pressures. The gage may be used as a readout device when measuring flowing fluids, pressure drop across filters, liquid levels in storage tanks and many other applications involving pressure, vacuum or differential pressure. Using the basic design of Dwyer's time-proven Magnehelic gage, the Capsuhelic gage contains a simple, frictionless movement that permits full scale readings as low as 0.5 in H2O. The pressure being measured is held within a capsule which is an integral part of the gage. This containment of the pressure permits the use of the gage on system pressures of up to 500 psig, even when differentials to be read are less than 0.1 in H2O. The diaphragm-actuated Capsuhelic gage requires no filling liquid which might limit its outdoor applications. Zero and range adjustments are made from outside the gage, and there is no need to disassemble the gage in normal service.

Precision Monitoring for Critical Applications

The Dwyer 4000-0 Capsuhelic Differential Pressure Gauge ensures highly accurate readings with a 2% full-scale accuracy and fine 0.01 in. WC resolution. Its industrial-grade construction and robust sensor make it an excellent choice for sensitive areas like clean rooms, HVAC balancing, filter maintenance, and fan/blower monitoring. Instantaneous response time allows for real-time system evaluation and tuning.


Versatile Mounting and Easy Installation

Designed for convenience, the gauge supports surface, flush, and pipe mounting options, offering flexibility for various system layouts. Both side and back 1/8 female NPT connections allow easy integration into existing setups. Installation is straightforward with the included mounting hardware, adapters, fittings, and a comprehensive instruction manual.


Built to Last in Demanding Environments

Protected by a die-cast aluminum case with a powder-coated finish and a NEMA 2 (IP54 equivalent) enclosure, the Dwyer 4000-0 withstands tough conditions. Its broad operating temperature range (-20C to 60C) and resistant silicone seals ensure longevity and reliability, even in challenging industrial or commercial environments.
