DWYER INSTRUMENTS Differential Pressure Gauges Dwyer Instruments differential pressure gauges are visual indicators designed to measure and illustrate the difference between two pressure points within a process system. These gauges offer a full-scale accuracy of 2% while measuring positive, negative or differential pressure values. The unique design of these units is capable of resisting shock, vibration and over-pressures with no manometer fluid to evaporate and freeze, as well as cause toxic or levelling problems. They are also suitable for checking the gas-air ratio control and monitoring blood and respiratory pressures in medical care equipment. Choose from a range of these differential pressure gauges available in 4 inch and 4-1/2 inch dial sizes on Raptor Supplies.

Features
- Dwyer Series 2000 Magnehelic differential pressure gages uses frictionless Magnehelic gage movement for accurate measurements without requiring any power at low costs.
- They are used during monitoring of filter, air velocity, blower vacuum, fan pressure & area pressures.
- These Magnehilic gauges have die-cast aluminium casing and bezel & acrylic covering with IP67 rating.
- They have 2 pairs of 1/8 inch female NPT connections (1 pair each of high and low-pressure taps).
- Their break-resistant plastic face with precision litho-printed scale provides clear reading visibility even from a distance.
- Their blowout plug vents the interior in case of overpressures.
- Dwyer Series A3000 Photohelic switches / gauges combine the benefits of pressure switches to the Magnehilic gauges and are ideal for air conditioning systems, clean rooms & fume exhaust systems.
- These Dwyer pressure gauges are equipped with two phototransistor-actuated DPDT relays for low & high-pressure limit control using knobs located on the gauge face.
- Gauge reading of these switches remains unaffected by switch operation, even without electrical power.
- These switches / gauges accept 10A current at 28VDC or 120 / 240VAC supply through their screw terminals.
- Their glass-epoxy printed circuit boards & plastic enclosure protect the electrical circuits & ensure durability.
- They feature switch set pointers that display the switch set point settings at all times and their spring-loaded friction clutch protects the set point mechanism from operator damages.
Working Mechanism
- For Dwyer Series 2000 Magnehelic differential pressure gages, set the gauge pointer on the zero mark by adjusting the screw at the bottom of the cover after the high & low-pressure taps are opened to the atmosphere.
- During positive pressure, connect tubing from the source to one of the high-pressure ports and then vent the low-pressure ports to the atmosphere.
- During negative pressure, connect the vacuum tubing source to the low-pressure port & then vent the high-pressure ports to the atmosphere.
- Durng differential pressure, connect the greater pressure source to high-pressure port and lower pressure source to low-pressure port.
- After ensuring that unused ports are plugged, the units show the correct pressure.
Standards and Approvals
- CE
- RoHS
- CSA
- UL
Frequently Asked Questions
Do these Dwyer pressure gauges require maintenance?
These Dwyer pressure gauges require no lubrication or periodic servicing. Users just need to keep the case exterior & cover clean and disconnect the pressure lines sometimes to vent gauges to the atmosphere for re-zeroing.
How to install Dwyer Series 2000 Magnehelic differential pressure gages?
- Select a mounting position that is free from excess vibration & direct sunlight and temperature is below 140 degrees F (60 degrees C).
- Longer tubing lengths may not affect the accuracy but can increase the response time.
- Use supplied mounting hardware / machine screws to secure the gauge in place. Users need to buy an optional A-610 pipe mounting kit for mounting the unit on a pipe.
What accessories are compatible with these Dwyer pressure gauges?
These Dwyer pressure gauges are compatible with differential pressure switches that control the flow rate / volume passing through the system. They can also accommodate tubing & mounting adapters for quick connections & installations.
