Dwyer Photohelic Pressure Gauge & Switch. 3-in-One Indicating Gage, Lo-limit and Hi-Limit Control. Photohelic Switch/Gages function as versatile, highly repeatable pressure switches combined with a precise pressure gage employing the time-proven Magnehelic design. The Photohelic measures and controls positive, negative or differential pressures of air and compatible gases.
Starting at just $55, these gauges certainly give a lot more value for money. Applications of the Magnehelic Gauge. There are various applications where there are needs for an accurate pressure reading. Magnehelic gauges are commonly used in HVAC applications; they are used to measure fan and blower pressures.They can also tell whether the air filters need replacement or not.his is the main difference that magnehelic differential pressure gauges have over the other gauges that use mechanical means to transmit the readings. This lack of physical contact between the parts mean that there is no wear inside the system that can affect the instrumentâs accuracy in any way.
