Series 4000 Capsuhelic® Differential Pressure Gage
Measures Pressure, Vacuum or Differential, Suitable for Internal Pressures to 500 psig
The Series 4000 Capsuhelic® Differential Pressure 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. 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 w.c.
Note: May be used with Hydrogen. Order a Buna-N diaphragm. Pressures must be less than 35 psi.

Questions
- Question
- Which Capsuhelic® gage ports could be connected to the pressure source in liquid service?
- Answer
- The bottom ports. This allows bleeding of entrapped air from the top ports to eliminate reading error due to compression of entrapped air in the gage. Bleed fittings should be installed in the top ports.
- Question
- Can the standard Magnehelic® or Capsuhelic® gage be installed outdoors?
- Answer
- Yes. Front covers are sealed with "O" rings. Capsuhelic vent holes are plugged with foam, and the new high impact acrylic lens material is very resistant to ultra-violet fogging. Additional care is recommended to lead pressure connections downward from the gage and provide as much protection from the elements as possible
- Question
- Why must Dwyer pressure switches be mounted with the diaphragm in the vertical plane?
- Answer
- In other than a vertical plane, the diaphragm can sag and cause a shift in set-point or a change in the adjustable set-point range. The switch may even fail to reset at the minimum set-points. This is the same phenomena that causes inaccuracy in Magnehelic® and Capsuhelic® gages when mounted in other than a vertical position.
- Question
- What might be the cause for Magnehelic® gages filling approximately 1/3 full of water, with lots of liquid droplets on the glass. Both are outside mounted on the side of an air stripping tower. One is a differential pressure gage that measures the pressure drop across a pitot tube. The other just measures the back pressure in the stripper. What can be done to fix the malfunction?
- Answer
- It looks like you’re getting some condensation in the Magnehelic®, which is causing it to collect on the bottom of the face. Since the Magnehelic® is not encapsulated, it is not recommended to be used in applications where moisture can form. One option to fix the problem is installing a liquid filter (like an F222) to filter out that moisture. Another option is to install a Capsuhelic (Series 4000), which is made to handle both air and liquid.
