Magnehelic Gauges Magnehelic Gauges
This MAGNEHELIC®Principle is a method of transmitting the effects of changes in air pressure from a diaphragm to an indicating pointer—by means of magnetic linkage and without the use of gears or other direct mechanical linkages. This system avoids wear and physical contact, which might destroy the accuracy and sensitivity of the instrument. It delivers accuracy to within 2% of full scale. Complete information.

PHOTOHELIC Pressure Control PHOTOHELIC® Pressure Control
PHOTOHELIC®models combine the MAGNEHELIC® gauge with a precise pressure switch that lets you control low and high gas pressures. Knob controls adjust dual set points, which allow for variable deadband control. These set points contain photocells that actuate DPDT relays when room pressures reach a preset upper or lower limit, and they can be set up to control corrective damper action. As the room pressure changes in response to damper motion, and the indicator returns to the null band, damper motion is halted. Complete information.
