Pressure Gauge

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 Catalogue： DPG51 differential pressure gauge   930KB
