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® contains a simple, frictionless
movement that permits full scale readings as low as 0.5 inch water
column. 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 inch W.C.
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.
PHYSICAL DATA
Ambient temperature range: 20° to 200°F.
Pressure Rating: -20" Hg to 500 psig.
Standard Ranges: See chart below.
Accuracy: Plus or minus 3% of full scale at 70°F. (2% on
4000S models, 4% on 4215, 4220, and 4500).
Housing: Die cast aluminum with impregnated hard coating,
standard. Optional forged brass housing is required for water or
water based fluids. For corrosive gases or liquids and for special
diaphragms, contact the factory.
Exterior Finish: Baked dark gray hammerloid.
Connections: 1/4" NPT high and, low pressure taps, duplicated
-one pair top for air and gas, and one pair bottom for liquids.
Standard Accessories: Two 1/4 NPT plugs for duplicate pressure
taps, four flush mounting adaptors with screws and four surface
mounting screws.
Dimensions: 5" diameter x 3 3/32" length.
Weight: 3 lbs., 3 oz. aluminum case; 7 lbs., 13 oz. brass
case.
Mounting
Capsuhelic® gages may be flush mounted in a panel or
surface mounted. Hardware is included for either. For flush mounting,
a 4 13/l6" diameter cutout in panel is required. Where high
shock or vibration are problems, order optional A-496 Heavy Duty
flush mount bracket. Optional A-610 kit provides simple means of
attaching gage to 1 1/4-2" horizontal or vertical pipe. Installation
is same as Magnehelic® gage. All standard models are
calibrated for vertical mounting. Gages with ranges above 5 in.
w.c. can be factory calibrated for horizontal or inclined mounting
on special order.

OPTIONS AND ACCESSORIES
Adjustable
signal flag--Integral with plastic gage cover; has external
reset screw. May be ordered factory installed on gage or separately
for field installation. Specify ASF suffix after model number.
A-314 bleed fitting--For
easier, safer purging of trapped air when using gage with liquids.
Also useful for draining condensate when installed in lower ports.
To open, simply loosen hex nut. Solid brass.
Forged brass case--For
applications involving water or water based liquids. To order, add
suffix "B" after model number. Example: 4205B.
A-471 portable
kit--includes plastic case, mounting bracket, A-309 3-way
manifold valve, (2) A-230 high pressure hoses and all necessary
fittings. Assembly required. Gage not included.
Transparent scale
overlays- Available in bright red or green to accent
critical pressure zones. Specify which color and portion of scale
to be covered with each.
- Bezel provides flange for flush mounting
- "O" ring seal for cover assures dust tight
integrity of case
- Clear plastic front cover is highly resistant to breakage.
Provides undistorted viewing of pointer and scale.
- Precision scale, litho-printed on aluminum, is accurate
and easy to read.
- Red tipped pointer of heat treated aluminum tubing is
easy to see. It is rigidly mounted on helix shaft.
- Pointer stops of molded rubber prevent pointer over-travel
without damage.
- Samarium cobalt magnet mounted at end of range spring
rotates helix without mechanical linkages.
- "Wishbone" assembly provides mounting for
helix, helix bearings and pointer shaft.
- Thin wall magnetic "window" is well braced
and of minimum area for maximum pressure capability.
- Sapphire bearings for helix are shock- resistant mounted.
They provide virtually friction-free rotation for helix. Rotation
is damped with high viscosity silicone fluid.
- Helix is precision milled from an alloy of high magnetic
permeability, deburred and annealed in a hydrogen atmosphere for
best magnetic qualities. Mounted in sapphire bearings, helix rotates
to align with magnetic field of magnet and transmit pressure indication
to pointer.
- Zero adjustment screw is conveniently located in plastic
cover, accessible without removing cover. "O" ring seal
provides dust seal.
- Range spring calibration is screw adjusted. Rate adjust
and rate adjust lock are coaxial and are factory set and sealed.
- Top low pressure connection (for Air or Gas) connects
to chamber in back of diaphragm. High pressure air or gas port
(cut away; not shown) connects with chamber in front of diaphragm
through passageways in case.
- Precision made case is offered in two materials. Standard
is die cast aluminum coated inside for resistance to most oils
and similar fluids. Optional forged brass case is recommended
when using water or water based liquids. One case size for all
pressure ranges--can be either surface or flush mounted.
- Silicone rubber diaphragm with integrally molded "O"
ring is sealed between the case and backplate. Diaphragm motion
is restricted to prevent damage due to over-pressure. Double convolution
allows choice of effective areas to suit range at time of assembly.
- Diaphragm support plate of stainless steel minimizes
position or attitude sensitivity.
- Calibrated range spring is a flat leaf of stainless
steel. Small amplitude of motion assures consistency and long
life. It reacts to pressure on diaphragm. Live length factory
adjusted for calibration.
- Range spring mounting plate provides mounting for rate
adjust screw and for the calibration range spring and magnet assembly.
- Bottom high pressure connection (for Liquids) connects
to chamber in front of diaphragm. Low pressure liquid connection
(not visible) connects with chamber in back of diaphragm through
passage
