Dwyer 2000-HA Series Magnehelic® high-accuracy differential pressure gauge
High-accuracy Magnehelic differential pressure gauge, accuracy ±1% FS, mirror scale eliminates parallax, supplied with six-point calibration certificate.
- Original Factory Genuine, Tenfold Compensation for Counterfeits
- Full Machine Warranty, Lifetime Maintenance
- In Stock, Shipped on the Same Day
The 2000-HA Series high-accuracy Magnehelic differential pressure gauge achieves ±1% FS, twice that of the standard 2000 Series, and comes standard with a mirror scale cover to eliminate reading parallax. Each unit is supplied with a six-point calibration certificate, IP67 protection, with optional 304 stainless steel bezel.
| Parameter Name | Technical Specifications |
|---|---|
| Main specifications | |
| Medium | Air and non-combustible, compatible gases (natural gas available as an option). Note: can be used with hydrogen. Order a BUNA-N diaphragm option. Pressure must be less than 35 psi |
| Wetted materials | Consult factory |
| Housing | Die-cast aluminium housing with acrylic plastic cover. Grey surface finish, withstands 168-hour salt spray corrosion test |
| Accuracy | ±1% FS (±1.5% on -0, -100PA, -125PA, -10MM and ±2% on -00, -60PA, -6MM ranges) throughout range at 70°F (21.1°C). |
| Pressure Resistance | -20 in Hg to 15 psig (-0.677 bar to 1.034 bar). |
| Overpressure | The pressure relief plug opens at approximately 25 psig (1.72 bar); standard models only. Refer to the overpressure protection notes on the catalogue page. |
| Temperature resistance | 20~40°F (-6.67~60°C). |
| Size | 4" (101.6 mm) dial diameter |
| Mounting orientation | Diaphragm in vertical position. Consult factory for other orientations. |
| Process connection | 1/8" NPT female thread, one high-pressure port and one low-pressure port on the side and rear respectively |
| Standard accessories | Two 1/8" NPT plugs, two 1/8" NPT fittings for rubber tubing, and three fittings and screws for flush mounting (on medium and high pressure instrument accessories, a ring retainer replaces the 3 fittings). |
