Series PS Pressure Snubber

Designed to protect pressure instrumentation by dampening surges and pulsations and assuring steady average pressure readings. Snubbers are available in a variety of pore sizes for use with gases, water, and oils.

A-464 Flush Mount Kit

The A-464 Mounting Kit provides a flush mounting solution for Magnehelic® gage installations for applications such as clean rooms and mechanical equipment rooms. The A-464 can also be used as an alternative means to flush mount Magnehelic® gages on control panel enclosures. The space pressure reference port eliminates the need to drill separate holes and run tubing long distances. Utilizing the A-464 for Magnehelic® gage installations reduces installation time while also producing an aesthetically pleasing result.

A-465 Space Pressure Sensor

The A-465 Space Pressure Sensor provides a clean solution for sensing space pressure. Typical applications include: sensing the pressure in clean rooms, laboratories and building lobbies. The kink resistant tubing provided in the kit is connected to the tubing running to a pressure transducer, Magnehelic® gage, VAV unit or any other types of pressure sensing devices. The sensor can be mounted on sheet rock walls, single gang electrical boxes or on ceiling tiles. The block free pressure reference opening along with the kink resistant tubing ensure accurate readings at all times.

SWUK1 Strap Wrench

The SWUK1 offers the user a versatile tool to grip, undo & tighten a wide variety of awkwardly shaped and sized objects. The SWUK1 also makes the job of fitting Adjustable Signal Flags (ASF) covers to Magnehelic® Differential Pressure Gages much easier by simply following the instruction included with each cover supplied.

Gage Tubing Accessories

Clear PVC tubing is easily inspected and is therefore best for test applications where a possibility of fluid entering the tubing exists.
Rubber tubing has less tendency to kink in storage and occupies less space, thus is best for portable work.
Aluminum tubing is recommended for permanent installations.
Flexible double column tubing is used with Mark II Manometers and the Wind Speed Indicator.
Norprene® tubing is useful in a wide range of temperatures from -75 to 275°F (-60 to 135°C)and will not weaken after long term exposure to heat and ozone.
Flexible colored vinyl tubing is quickly distinguishable in applications where more than one line is required aiding installation.
Black nylon tubing is recommended for high temperature and pressure applications.
Black plenum fire retardent polyethylene tubing meets NFPA standard 90A for installation in air-conditioning and ventilating plenum spaces; also used in building automation systems.

Stainless Steel Static Pressure Tips & Accessories

These sensors are for use with Manometers, Magnehelic® Gages, Pressure Switches and other Controllers to pick up or sense static pressure drop across air filters and cooling coils, blower input and discharge pressures, etc. The angled tips shown have 4″ insertion depth. Each has four radially drilled .040″ sensing holes. All except Model A-303 mount in 3/8″ hole in duct. For portable use, a magnet holds No. A-303 in place. No. A-305 is used where a very low actuation or sensing point is required on a pressure switch or gage or where response time is critical. No. A-307 and A-308 are suitable for use in low velocity systems or where the need for accuracy is less critical.

A-286

The new mounting flange can be used on any Dwyer Instruments, Inc. gage that possesses a 4-1/2″ (115 mm) diameter housing. The flange is secured to the gage behind its bezel with three set screws. The set screws hold the gage tight in place. The gage/flange can then be quickly attached to a surface or panel with a drill and the supplied mounting screws. The flange’s three mounting holes follow the industry standard mounting pattern. The flange is made of a robust plastic composite and comes with three pre-installed set screws, an Allen wrench for tightening and three flange mounting screws.

Included Accessories:
(3) Pre-installed metal set screws
(3) Mounting screws
(1) Allen wrench
(1) Instruction manual with mounting template

Series A-320

Series A-320 Instrument Enclosure protects instruments in all applications. The A-320-A fits standard Magnehelic® size instruments (4-9/16″ diameter) and the A-320-B fits standard 3000MR Photohelic® switch/gage size instruments (4-13/16″ diameter). Both models include silicone tubing, gage barbs and mounting hardware.

Series A-170

The 316 Stainless Steel Siphons protect pressure instruments in high temperature applications. Water held in the 180° coil prevents steam from contacting the instrument. Constructed with 316 stainless steel, the A-170 siphons offer the best resistance to corrosion, high temperature, and pressure. They are ideal for use with pressure gages and instrumentation where the process media temperature exceeds the rating of the instrument. The male NPT connection allows for easy installation and secure attachment.

Series A-169

The Carbon Steel Siphons protect pressure instruments in high temperature applications. Water held in the 180° coil prevents steam from contacting the instrument. Constructed with carbon steel, the A-169 siphons can withstand high temperature and pressure. They are ideal for use with pressure gages and instrumentation where the process media temperature exceeds the rating of the instrument. The male NPT connection allows for easy installation and secure attachment.
