Overview of Series 2000, 3000, and 4000 Differential Pressure Gauges

1. Magnehelic® Differential Pressure Gauge (Series 2000):
   • The Magnehelic gauge is the most popular and reliable gauge for measuring low differential pressures.
   • It features a simple, easy-to-read dial and provides accurate readings of low pressures across a range of 0.25 to 60 inches of water column (in. w.c.).
   • Applications: Commonly used in HVAC systems, cleanrooms, filter monitoring, and other low-pressure applications where high accuracy is essential.
2. Capsuhelic® Differential Pressure Gauge (Series 3000):
   • The Capsuhelic gauge is designed for direct readings of differential pressure and static pressure.
   • It is unique for its capsule design, providing pressure ranges from 0 to 50 PSI, suitable for applications that require higher pressures than Magnehelic gauges.
   • Applications: Used in applications such as filtration, fan and blower pressure, and liquid level monitoring.
3. Photohelic® Differential Pressure Switch/Gauge (Series 4000):
   • This series combines the functionality of a pressure gauge and a switch, allowing it to control processes as well as provide pressure readings.
   • The Photohelic gauge is unique in that it includes setpoints, which can activate alarms or other control systems when the pressure goes above or below the desired range.
   • Applications: Ideal for critical applications like dust collection, cleanroom monitoring, and process control in industries such as pharmaceuticals and food processing.

Key Benefits and Features
