DPG51 Differential pressure gauge
This differential pressure gauge measures fan and blower pressure, filter resistance, wind speed, furnace pressure, orifice plate differential pressure, bubble water level, and hydraulic system pressure.
Differential Pressure Gauge is designed for rapid and reliable indication of positive, negative (vacuum), or differential pressures without requiring external power. Based on featuring a frictionless design, it ensures long-term durability and high resistance to shock, vibration, and over-pressures. The device is IP67 weatherproof rated and offers NIST calibration and compatibility with hydrogen when configured with a Buna-N diaphragm.
Key Specifications:
• Core Function: Visual monitoring of positive, negative, or differential pressure
• Switch Mechanism: Frictionless design
• Mounting: Compact IP66 housing for versatile environmental integration
• Compatibility: Clean room, HVAC, medical, and industrial monitoring systems
Typical Applications:
✔ Filter resistance monitoring
✔ Air velocity measurement (with Pitot tube)
✔ Blower and vacuum system pressure indication
✔ Duct and clean room pressure management
✔ Furnace gas differential monitoring
✔ Medical instrumentation and respiratory systems
