Before installation, please ensure that the location is free from excessive vibration and that the ambient temperature will not exceed 140°F (60°C). It is also important to avoid direct sunlight, which can accelerate discoloration of the clear plastic cover.
Sensing lines may be run at any necessary distance per application requirements. Long tubing lengths will not affect the accuracy of the gage, but will increase response time slightly. Do not restrict lines. If pulsating pressures or vibration causes excessive pointer oscillation, consult the factory for ways to provide additional damping.
All standard Magnehelic® Differential Pressure Gages are calibrated with the diaphragm in the vertical position, and should be used in that position for maximum accuracy. If gages are to be used in orientations other than the vertical position, please specify this information when ordering. Many higher range gages will perform within tolerance in other positions after re-zeroing. Low range models of 0.5” w.c. plus 0.25” w.c. and metric equivalents must be used in the vertical position only.
All Magnehelic® gages come with standard mounting hardware for the unit to function, including: tubing adapters, screws, and port plugs. Mounting brackets and enclosures are not included and must be ordered separately.
