Three-Way Valve Three Way valves are for pneumatic tubing systems. Dwyer's instruments are able to hook 3 instruments together, tests various gages and transmitters. Constructed of solid gray PVC, has Buna-N seals, and a rotating flag handle. The handle has 180° rotation and lies directly over the open port. View More

Gage Guards/Pressure Snubbers Pressure snubbers protect pressure instruments from pressure surges. Gauge guards provide a protective barrier between the process fluid and the instrument. The adjustable pressure snubbers are fine thread adjustable valves that allow you to fine tune harmful harmonic vibration from the fluid systems. View More

Pneumatic Valves Pneumatic valves are directly for pneumatic tubing systems. View More

Pneumatic Fittings Pneumatic fittings are for pneumatic tubing systems. View More

Fittings, Stainless Steel Pneumatic fittings are made of stainless steel. Dwyer's fittings are designed and manufactured to provide reliable leak-free connections in a variety of applications. The tubing material chosen must be compatible with the system's contained media, pressure and temperature, as well as with the environment in which it will be installed. View More

Fittings, Nylon Pneumatic fittings are made of nylon. Nylon fittings are generally acceptable for use at working pressures up to 150 psi at normal room temperatures, and at very low pressures, temperatures can approach 175°F. View More

Static Pressure Sensors Static Pressure sensors are for use with pressure gages, switches, transmitters and other controllers to pick up or sense static pressure drop across air filters and cooling coils, blower input and discharge pressures, etc. View More

Valves / Connectors Valves and connectors are for pneumatic tubing systems. Specifically for manometers and gages. Instrument valves are for permanent installation. View More

Fittings, Filters & Mufflers Fittings, filters, and mufflers to pneumatic tubing systems. Special line filters for gage and particulate filters. The Muffler Accessory can be easily field installed to any diaphragm valve with an exhaust. Particulate filters are used for Dwyer Flowmeters to keep the air clean. View More

Mounting Options Mounting flanges and brackets for pressure gages. Various mounting options for Dwyer products. Enclosures protects instruments in all applications. View More

Carrying Cases Portable case accessories for test equipment. Steel cases are substantially constructed and finished in gray hammerloid. Molded plastic cases are gray, high density polyethylene. View More

Psychrometer & Slide Charts Sling psychrometers and calculator slide charts. Psychrometers are used for handheld, non-electric humidity metering. Air Velocity Calculator Slide Charts make spot checking with Dwyer Pitot Tubes quick and easy. View More

Air Filter Kits Accessory kits are for pressure instruments to measure filter pressure drop. They are used with differential pressure gages or switches to measure the resistance of air flow through filters. View More

Gage Fluids Fluids for Dwyer Products Gage fluids in the 1 ounce size are furnished in unbreakable plastic dispenser type bottles. Use only Dwyer fluids in Dwyer gages. Red gage fluid, blue gage fluid, and fluorescein green color concentrate. View More

Technical Reference Books Technical references for HVAC, pumps, boilers, electrical codes, instrumentation, chemical resistance, indoor air quality, facilities, plant management, and more. View More

Regulator Kit Flow regulator kits for RM and VF flowmeters. Recommended for use where inlet air pressure fluctuates widely and constant flow is required. For higher flow rates, factory needs to be consulted. View More

Tubing Tubing for pneumatic systems. The different types include Clear PVC tubing, rubber tubing, aluminum tubing, flexible double column tubing, Norprene tubing, flexible colored vinyl tubing, and black plenum fire retardant polyethlene tubing. View More

Siphons Siphons protect pressure instruments in high temperature applications. Water held in the 180° coil prevents steam from contacting the instrument. Ideal for use with pressure gages and instrumentation where the process media temperature exceeds the rating of the instrument. View More

Thermocouple Wire General purpose thermocouple wire is offered in the two most common types of thermocouples used, type J and type K. Both FEP insulation and Fiberglass insulation options are available in multiple pre-spooled lengths meeting any application needs. View More

Question

Will a Dwyer pressure switch be damaged if the pressure exceeding the maximum set-point is applied to the switch?

Answer

No. Not unless the maximum pressure rating of the switch is exceeded.

Question

How do I hook up my Magnehelic® gage for an air velocity application with a pitot tube?

Answer

In our Application Guides on flow products, we explain very well how to take air velocity readings. The total pressure connection on the pitot tube is connected to one of the high pressure ports on the gage. The other high pressure port is plugged. The static pressure connection on the pitot tube is connected to one of the low pressure ports on the gage. The other low pressure port is plugged.

Question

Trying to measure differential pressure between OSA and indoors. Using transmitters with a range of +25pa to -25pa. Monitoring pressure variations occur from basically 0pa to 20pa over a short period of time (15 to 30 sec) Building is basically closed during testing, suspect OSA fluctuating due to winds? eddy currents etc. Any ideas, Building under positive pressure is critical for safety reasons Any ideas?

Answer

Whenever you are using outside air for a static pressure reference, fluctuations in outside conditions can cause erratic differential pressure readings. By using one of our outdoor static reference probes, you can diminish the influence of outdoor weather on your reading.

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.
