Product Details:
The Dwyer 3000MR Series Photohelic® differential pressure switch/gauge combines two versatile, precise pressure switches with a time-proven Magnehelic® pressure gauge. The gauge reading is unaffected by switch operation. External knobs are used to adjust the two DPDT switch set points. Switch set points (indicated by red pointers) and system pressure are fully visible at all times. Ranges are available from 0in to 0.25in W.C. up to 10'' W.C. full scale. The 3000MR Series may be ordered with the switch assembly remote mounted to facilitate panel mounting.
