Frequently Asked Questions

What is the Dwyer A3002 differential pressure gauge and switch used for?

The Dwyer A3002 Photohelic Series A3002 is used to measure and control low differential air or non-combustible gas pressures in HVAC, cleanroom, and industrial ventilation systems. Its built-in switch provides alarm or control output at a setpoint, making it ideal for filter monitoring, duct static pressure, and flow sensing applications.

What are the specifications of the Dwyer A3002 differential pressure gauge and switch?

The Dwyer A3002 is a single-side differential pressure gauge and switch from the A3000 Photohelic Series. It uses a diaphragm sensor, has ±2% gauge accuracy, a die cast aluminum housing, and 1/8 in NPT female connections. It does not include a certificate of calibration. The manufacturer part number is A3002.
