Differential Pressure Gauges
Differential pressure gauges measure pressure differences precisely, enabling accurate filter monitoring and flow control in industrial applications.
Differential Pressure Gauges
Differential pressure gauges measure and visually indicate the pressure difference between two distinct points within industrial process systems. Utilizing dual sensing elements—such as diaphragms, bellows, or Bourdon tubes—they mechanically translate pressure differential into precise pointer movements displayed clearly on an analog dial.
Their capability to accurately monitor differential pressures is critical for evaluating system performance, detecting filter clogging, measuring fluid flow rates, and assessing equipment condition. By visually identifying pressure variations in real-time, differential gauges help maintain operational safety, enhance process efficiency, optimize energy usage, and reduce the risk of unexpected equipment downtime.
Typical applications for differential pressure gauges include filtration systems in chemical processing, oil and gas pipelines, HVAC air handling units, heat exchangers, pump performance monitoring, and flow measurement across orifice plates in fluid distribution systems. They are essential for maintaining process reliability and ensuring compliance with operational and regulatory requirements.
Constructed with durable materials such as stainless steel, brass, or specialty alloys, differential pressure gauges often feature rugged housings and options such as liquid-filled cases for vibration resistance. Models certified for hazardous environments (ATEX, IECEx) offer safe, dependable performance in potentially explosive or challenging industrial conditions.
