About Dwyer 4040 Capsuhelic Differential Pressure Gauge

Dwyer 4040 Capsuhelic Differential Pressure Gauge

Dwyer Instruments 4040

Capsuhelic Differential Press. Gauge, 0-40 in H2O, brass case

Differential pressure gage, range 0-40" 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.

FAQs of Dwyer 4040 Capsuhelic Differential Pressure Gauge:

Q: How do I install the Dwyer 4040 Capsuhelic Differential Pressure Gauge?

A: The Dwyer 4040 can be panel or surface mounted using the included mounting hardware. Connect the 1/8" NPT brass ports to your systems differential pressure points, ensuring compatibility with air or non-combustible gas applications. Follow the instruction manual for detailed guidance.

Q: What is the maximum operating pressure and temperature range for this gauge?

A: The Dwyer 4040 is built to measure differential pressures up to 21 kPa (3 psi), and it operates effectively in ambient temperatures ranging from -7C to +60C (20F to 140F), making it suitable for most industrial environments.

Q: How is zero adjustment performed on this gauge?

A: Zero adjustment is done externally via a dedicated screw on the unit. This allows users to recalibrate the pointer to zero without dismantling the gauge, maintaining measurement accuracy after installation or over time.

Q: Where can I use the Dwyer 4040 Capsuhelic Gauge?

A: This gauge is ideal for industrial applications requiring differential pressure measurement of air or non-combustible gases, such as HVAC monitoring, filter condition tracking, and cleanroom systems, thanks to its rugged build and 2% accuracy.

Q: What are the materials used in the construction of the Dwyer 4040?

A: The gauge features an anodized aluminum case, shatter-resistant polycarbonate window and dial, brass ports, a silicone rubber seal, and an aluminum pointer. These materials ensure reliability, safety, and a long service life in industrial settings.

Q: What are the main benefits of using the Dwyer 4040 Capsuhelic Gauge?

A: Key benefits include precise analog display, robust construction, ease of zero adjustment, versatile mounting options, and dependable operation in a wide range of temperatures and pressures for air and non-combustible gas systems.
