Understanding Differential Pressure Gauge Types and Manufacturers

Differential pressure gauges are essential instruments used across various industries to measure the difference in pressure between two points. This measurement is crucial for monitoring system performance, ensuring safety, and maintaining efficiency in operations. As a result, the market for differential pressure gauges is filled with various types and manufacturers, each offering unique features tailored for specific applications.

Types of Differential Pressure Gauges

1. Mechanical Differential Pressure Gauges These are the most traditional type and operate using a diaphragm or a Bourdon tube mechanism. They do not require any external power source, making them dependable and easy to use. Mechanical gauges are widely employed in HVAC systems, filtration monitoring, and across many industrial processes.

2. Electronic Differential Pressure Gauges These modern instruments utilize electronic sensors to measure pressure differences, offering higher precision and the ability to integrate with control systems. They often feature digital displays and can provide data logging capabilities, making them ideal for applications requiring precise measurements and monitoring over time.

3. Capacitance-based Differential Pressure Gauges These gauges employ capacitance sensors to determine pressure differences, providing high sensitivity and accuracy. They are suitable for low-pressure applications and can be used in industrial processes that require precise control, such as chemical manufacturing and pharmaceuticals.

4. Hydraulic Differential Pressure Gauges These gauges operate by using a liquid-filled system to measure pressure differences. They are commonly used in environments where temperature fluctuations may affect accuracy, as the liquid mitigates the impact of thermal variations.
