About Dwyer 4008 Capsuhelic Differential Pressure Gauge

Dwyer 4008 Capsuhelic Differential Pressure Gauge

Differential pressure gage, range 0-8.0" w.c.

The Capsuhelic gauge is designed to give fast, accurate indication of differential pressures. The gauge 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 gauge, the Capsuhelic gauge 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 gauge. This containment of the pressure permits the use of the gauge 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 gauge requires no filling liquid which might limit its outdoor applications. Zero and range adjustments are made from outside the gauge, and there is no need to disassemble the gauge in normal service. Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

The gauge comes with essential mounting accessories, supporting both surface and panel installation. Its compact, light build allows flexible integration into existing setups, while the external zero adjustment knob ensures user-friendly calibration without disassembling the unit.

Versatile Industrial Applications

Designed for a variety of settings, the Dwyer 4008 is suitable for measuring pressures in air handling systems, blowers, ducts, and controlled environments. The brass port fittings, silicone rubber seals, and white-finished metal dial with clear markings enhance usability, ensuring the gauge meets rigorous industrial standards in India and worldwide.

FAQs of Dwyer 4008 Capsuhelic Differential Pressure Gauge:

Q: How do I install the Dwyer 4008 Capsuhelic Differential Pressure Gauge?

A: The gauge can be surface or panel mounted using the two included brackets. Connect your 1/8 NPT female pressure lines to the brass ports, and make sure the unit is mounted vertically for accurate readings.

Q: What types of media can the Dwyer 4008 measure?

A: This gauge is designed to measure the differential pressure of air and other compatible gases. It should not be used for liquids or aggressive gases outside of specification.

Q: When should I use the Dwyer 4008 for filter monitoring?

A: Install the gauge across filters in HVAC systems to monitor pressure drops; rising differential pressure indicates filter clogging or a need for replacement, optimizing system performance and reducing energy costs.

Q: Where is the Dwyer 4008 commonly used?

A: Common applications include filter and fan monitoring, duct and room pressure measurement, clean rooms, and other industrial or laboratory environments demanding accurate low-pressure indication.

Q: What is the process for zero adjustment on this gauge?

A: Zero adjustment is straightforwarduse the external knob to set the pointer to zero before system pressurization, ensuring ongoing accuracy without opening the unit.

Q: What are the main benefits of the Dwyer 4008 Capsuhelic Gauge?

A: Benefits include instant response to pressure changes, robust acrylic construction, external zero adjustment, and high accuracy (2% F.S.). The analog display is clear and easy to read, enhancing operational efficiency.
