Dwyer 2220 W834 Magnehelic Pressure Gauge –
Dwyer 2220 W834 Magnehelic Pressure Gauge The Dwyer Series 2200 Current to Pressure Transducer combines low cost, accuracy and minimal air consumption with field-proven technology. Versatile design features a rugged, compact housing with a choice of FM approved explosion-proof or intrinsically safe operation when used with a suitable barrier. This transducer utilizes a practically weightless membrane that is electromagnetically positioned over the air flow, consuming minimal air and electrical energy while providing an accurate, precise output pressure signal. This low-mass membrane
