A-493

Overview

The Dwyer Instruments A-493 is an 8-inch (202 mm) straight stainless steel static pressure tip designed for accurate pressure sensing in ductwork and plenums. It features a mounting flange and is compatible with 3/16 inch tubing. This accessory facilitates precise connection to manometers, Magnehelic gauges, and pressure switches by providing a stable, flush-mounted interface for static pressure measurement applications.

Feature Summary

• Constructed from stainless steel for durability and corrosion resistance
• Includes a mounting flange for secure installation
• Designed for use with 3/16 inch tubing connections

Applications

• Connection to manometers for static pressure measurement
• Integration with Magnehelic gauges
• Use with pressure switches for system monitoring

Procurement Notes

Verify the specific length requirement, as other variants exist. Confirm compatibility with existing tubing diameter (3/16 inch). Ensure the mounting flange design matches the installation surface. Check for included accessories such as adapters or tubing if not purchased separately.

Selection Notes

Select this model when an 8-inch insertion depth is required for deep duct penetration. Choose stainless steel construction for environments requiring corrosion resistance. Ensure the application utilizes 3/16 inch tubing for proper fit. Verify that the mounting flange configuration suits the available space and installation method.

Part Context

This component belongs to the Dwyer Instruments static pressure tip series, which provides various lengths and configurations for HVAC and industrial pressure sensing. The A-493 specifically offers an extended 8-inch reach compared to shorter standard tips, allowing access to pressure points deeper within duct systems or equipment plenums.

Replacement Considerations

Consider the A-302 for shorter insertion depths. Verify if alternative brands offer equivalent 8-inch stainless steel tips with matching flange dimensions and tubing compatibility.
