Capsuhelic Differential Press. Gauge, 0-15 in H2O, brass case
Differential pressure gage, range 0-15" 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.

Accurate Differential Pressure SensingThe Capsuhelic 4015 uses a capsule-type differential pressure sensor, which ensures high precision for measuring pressures between 0-15 psi (0-1.03 bar). This makes the device well-suited for applications requiring swift, reliable readings, such as air filtration monitoring or maintaining positive pressurization in clean rooms. Instantaneous response time means operators see changes in pressure as they happen.
Designed for Industrial ReliabilityThis gauge is engineered for durability with a die-cast aluminum case and a powder-coated steel front flange, complemented by a matte white aluminum dial for clear visibility. The IP54 rating (front side) protects against dust and moisture, making it suitable for challenging industrial settings. Its external zero adjustment knob allows for easy recalibration without dismantling the gauge.
Flexible Mounting and Simple OperationThe Dwyer 4015 can be installed vertically, either flush or surface mounted, thanks to the included mounting bracket and hardware. With an easy-to-read analog dial and acrylic lens, technicians can quickly glance at readings. Threaded 1/8 NPT female pressure connections facilitate straightforward integration with existing systems.
FAQs of Dwyer 4015 Capsuhelic Differential Pressure Gauge:
Q: How is the Dwyer 4015 Capsuhelic Differential Pressure Gauge typically installed?
A: The gauge is designed for vertical mounting and can be installed either flush to a panel or surfaced-mounted using the included mounting bracket and hardware. Its 1/8" NPT female pressure connections ensure integration with standard fittings.
Q: What types of media can the Dwyer 4015 measure?
A: This gauge is intended for measuring differential pressure of air and compatible gases. Liquids or incompatible gases are not recommended as they may damage the capsule mechanism and seals.
Q: When should you use the Dwyer 4015 for filter monitoring?
A: You should use this device whenever you need to monitor pressure drop across filters, such as in HVAC systems, to assess filter condition and determine when replacement is necessary, ensuring efficient system performance.
Q: What is the benefit of the capsule sensor type compared to Bourdon tube mechanisms?
A: The capsule sensor inside the Dwyer 4015 is specifically designed for low pressure differentials, offering greater accuracy and responsiveness in such applications than a Bourdon tube, which is more suitable for higher pressures.
Q: How do you zero the gauge for accurate measurement?
A: The gauge features an external zero adjustment knob, allowing you to recalibrate the reading while in place, ensuring precise measurements without requiring gauge removal.
Q: Where can the Dwyer 4015 be used most effectively?
A: It is well suited for industrial environments such as air filtration systems, fan monitoring, and clean rooms, due to its rugged construction, IP54 front-side protection, and accuracy.
Q: What accessories are supplied with the Dwyer 4015 Capsuhelic Gauge?
A: Each unit comes with a mounting bracket and the standard hardware required for installation, making setup straightforward in new or replacement applications.
