Capillary Type Differential Pressure Gauges A Comprehensive Guide In the realm of industrial processes and scientific experimentation, the accurate measurement of pressure differentials is paramount. Capillary type differential pressure gauges are designed to meet these exacting demands, providing reliable and precise readings in a wide range of applications. This article delves into the intricacies of these sophisticated instruments, exploring their functionality, features, and applications. What Are Capillary Type Differential Pressure Gauges? Capillary type differential pressure gauges operate on the principle of capillary action, which refers to the ability of a liquid to rise or fall in a narrow tube or capillary due to intermolecular forces. In these gauges, a pair of capillary tubes connected to a differential pressure transducer is used to measure the pressure difference between two points. The liquid filled in the capillaries expands or contracts based on the pressure difference, which is then translated into an electrical signal by the transducer for display or recording. Key Components and Functionality The main components of a capillary type differential pressure gauge include the pressure sensing element, the transducer, the measurement and indication system, and the accessories. The pressure sensing element is typically made of stainless steel or another corrosion-resistant material and houses the capillary tubes. The transducer, which is the heart of the instrument, converts the physical pressure differential into an electrical signal that is proportional to the pressure difference. The measurement and indication system displays the pressure reading in a user-friendly format, while the accessories, such as switches and alarms, enhance the functionality of the gauge.
