Dwyer Instruments Inc. 2330 Differential Pressure Gauge 15-0-15" w.c

SKU CH-242W-7NJBX

Measures differential pressure across a 15-0-15 inches water column range with 1.00 inch minor divisions

  • TypeElectronic
  • Measures positive and negative differential pressure with a 15-0-15" w.c. range
  • Reads fine changes using 1.00" w.c. minor divisions
  • Handles high static loads rated to 15 PSIG total pressure
  • Suits vacuum and low-pressure systems with -20" Hg low-end rating
  • Electronic gauge design simplifies HVAC and process monitoring

Differential Pressure Measurement

The Dwyer Instruments 2330 is a differential pressure gauge built for technicians who need to read positive, negative or bidirectional pressure in HVAC, laboratory or industrial air systems. Its 15-0-15 inches water column range suits filter monitoring, duct balancing and clean-room verification where pressure swings both ways.

Mechanical Operation, Silent Use

The gauge operates without electronics, so it draws no power and produces no audible noise in normal service. A rated total pressure span of -20 inches Hg to 15 PSIG protects the movement against accidental over-pressure events during system start-up or purge cycles.

Pointer Scale With Minor Divisions

A clear dial graduated in 1.00 inch minor divisions lets operators interpolate readings quickly without digital conversion. Standard 1/8 inch NPT pressure connections accept common tubing and manifold fittings, allowing panel or in-line mounting with ordinary hand tools. Not suited for applications requiring data logging, remote transmission or ranges beyond the stated 15.0 inches WC span.

Questions about this item

How do I install the 2330 differential pressure gauge and what step is often missed?

Mount the gauge vertically, connect the high and low pressure ports to the correct process lines, and ensure the vent is open to atmosphere; the step most often missed is verifying the port orientation matches the 15-0-15" w.c. range direction.

What maintenance or replacement will the 2330 gauge need over time?

Periodically check the pointer for zero drift against the 1.00 minor divisions and inspect the diaphragm for contamination; recalibrate or replace the unit if readings exceed the rated total pressure limits of -20 inches Hg to 15 PSIG.

What limit appears first when the 2330 gauge runs under sustained differential pressure?

The 15.0 inches w.c. full-scale limit is reached before the 15 PSIG static pressure rating, so sustained differentials at the top of the range will hit the measurement ceiling first.
