What is the Dwyer A-306A static external pressure sensor used for?

The Dwyer A-306A measures static pressure in pneumatic systems and industrial process monitoring applications. Its 304 stainless steel sensing element integrates into compressed air lines and ventilation ducts for accurate pressure data collection across manufacturing and HVAC installations.

What are the specifications of the Dwyer A-306A pressure sensor?

The A-306A features a 304 stainless steel sensing element, 430 stainless steel flange, and 303 stainless steel connector. Available in three lengths—101 mm, 152 mm, and 203 mm—it connects via 3/16" tubing. All wetted materials are corrosion-resistant for industrial durability.

Where can I buy the Dwyer A-306A in Singapore?

3G Electric, an authorised industrial equipment distributor established in 1990, supplies the Dwyer A-306A (SKU: DWY90026) throughout Singapore. We handle full logistics, customs clearance, and delivery across Southeast Asia with comprehensive support.

How do I select the correct length for the Dwyer A-306A sensor?

Choose sensor length based on duct or pipe wall thickness and installation depth. The 101 mm, 152 mm, and 203 mm options accommodate different mounting configurations. Dwyer recommends consulting application requirements and available space before selection to ensure accurate static pressure measurement.
