Product Description

Dwyer A-305 is a low-resistance stainless steel static pressure tap for industrial measurement applications, featuring 3/16" tubing ID connection and 304 stainless steel probe construction. Ideal for HVAC and process systems requiring accurate pressure sensing at minimal flow restriction.

Frequently Asked Questions

What is the Dwyer A-305 static pressure tap used for?

The Dwyer A-305 is a low-resistance stainless steel static pressure tap used in HVAC and industrial process systems to measure static pressure in ducts and pipes with minimal flow restriction. It connects to differential pressure switches and transmitters, and is ideal for monitoring pressure drop across filters and cooling coils.

What are the specifications of the Dwyer A-305?

The Dwyer A-305 has a 101 mm probe length, a 3/16" tubing ID connection, and is constructed from 304 stainless steel probe, 430 stainless steel flange, and 303 stainless steel fitting. It is designed for simplified installation and accurate static pressure sensing in air velocities up to 1500 FPM.

Where to buy the Dwyer A-305 in Singapore?

You can source the Dwyer A-305 static pressure tap through 3G Electric in Singapore. We handle logistics, customs clearance, and delivery to your site, providing technical support for industrial measurement applications. Contact us for pricing and lead time on this Dwyer model.

How to install the Dwyer A-305 static pressure tap?

Install the Dwyer A-305 by mounting the flange with the integrated rubber gasket and two screws onto the duct or pipe. Connect 3/16" ID tubing to the barbed fitting. For accurate readings, position the probe away from duct walls to minimize turbulence effects, as recommended for permanent installations.
