Understanding the JAH Bourdon Type Differential Pressure Gauge

Differential pressure measurement is a critical aspect of various industrial applications, providing essential data for system monitoring, control, and optimization. Among the numerous devices available for measuring differential pressure, the JAH Bourdon type differential pressure gauge stands out for its reliability, accuracy, and ease of use. This article explores the fundamental principles, design, applications, and advantages of the JAH Bourdon type differential pressure gauge.

The Principle of Operation

At the core of the JAH Bourdon type differential pressure gauge is the Bourdon tube, a slender, curved tube that reacts to pressure changes. When a differential pressure is applied across the two ends of the tube, it causes the tube to straighten slightly. This movement is mechanically linked to a pointer that indicates the pressure reading on a calibrated dial. The Bourdon tube's ability to translate pressure into mechanical motion is what makes this gauge effective for measuring differences in pressure.
