Product Description

The DWYER Differential Pressure Gauge, model 2301 from Series 2000, is a low operating pressure differential gauge with a back/single-side connection. It features a 4-inch dial, 1/8-inch NPT female connections, and a diaphragm sensor type housed in die-cast aluminum with an IP67 rating. A certificate of calibration is not included with this unit.

Frequently Asked Questions

What is the Dwyer 2301 differential pressure gauge used for?

The Dwyer 2301 differential pressure gauge measures low differential pressure in HVAC, filtration, and process applications. Its diaphragm sensor and IP67-rated die-cast aluminum housing suit cleanrooms, air-handling units, and pump monitoring where reliable, low-pressure readings are critical.

What are the specifications of the Dwyer 2301 differential pressure gauge?

The Dwyer 2301 has a 4-inch dial, 1/8-inch NPT female back/single-side connection, diaphragm sensor, and die-cast aluminum housing with IP67 rating. It is part of Series 2000 and does not include a certificate of calibration. These specs define its low-pressure differential measurement capability.

Where to buy the Dwyer 2301 differential pressure gauge worldwide?

3G Electric supplies the Dwyer 2301 differential pressure gauge worldwide. As a global industrial sourcing partner, we handle logistics, customs clearance, and delivery to your site. Contact us for pricing and lead time on this model from Dwyer's Series 2000.

How to install the Dwyer 2301 differential pressure gauge?

Mount the Dwyer 2301 with the 1/8-inch NPT female connection in a vertical position for best accuracy. Use Teflon tape on threads to prevent leaks. Avoid over-torquing the die-cast aluminum housing. Connect high-pressure side to the marked port and low-pressure side to the opposite port.
