Precision and Safety in Operation

Calibrated specifically for differential pressure measurement, this instrument features an analog display with white-painted aluminium dial and black pointer for clear readability. Overrange protection up to 130% of full scale and external zero adjustment add layers of safety and accuracy to your operations.

FAQs of Differential Gauges:

Q: How do I install the differential gauge for best performance?

A: For optimal results, select the appropriate mounting methodsurface, panel, or flushaccording to your facilitys requirements. Utilize the back or bottom connection based on your piping layout, and ensure accessories like mounting brackets or panel mounting kits, if required, are secured. Proper installation aids in sustaining accuracy and prolonging gauge life.

Q: What applications is this differential gauge ideally suited for?

A: This gauge is purpose-built for clean rooms, HVAC systems, process industries, and filter monitoring. Its rugged design and precise calibration make it reliable for monitoring differential pressure in applications involving air, gas, or other non-corrosive fluids.

Q: When should I adjust the zero setting on the gauge?

A: You should perform external zero adjustment when you notice any deviation from zero under no pressure condition. This external feature allows for on-site calibration, ensuring measurement reliability without dismantling the gauge.

Q: Where can I use this gauge considering its protection class and temperature range?

A: Given its IP55 protection and operating temperature range of -20C to +60C, the gauge is suitable for both indoor and moderately harsh or dusty environments, providing robust performance in various industrial settings.

Q: What is the process behind its precise differential pressure measurement?

A: Utilizing a mechanical sensor with a Bourdon tube made from phosphor bronze, the system translates differential pressure into pointer movement on an analog dial, calibrated to offer high accuracy (1.6% F.S.) across specified scale ranges.

Q: What are the key benefits of using this differential gauge in industrial applications?

A: Key benefits include ease of installation, weatherproof construction, externally accessible calibration, broad compatibility with process connections, and reliable performance for safety-critical measurement needs. The durable construction ensures longevity and minimal maintenance.
