Pressure Accessories

An armoured capillary tube is used on a pressure gauge to safely transmit pressure from a remote process point to the gauge while protecting the sensing line from damage. The capillary tube is typically small and flexible, allowing the gauge to be mounted away from high temperatures, vibration, corrosive fluids, or hazardous areas. The armouring, usually stainless steel braid or spiral wrap, provides mechanical strength, preventing kinks, crushing, or abrasion that could cause leaks or inaccurate readings. It also enhances durability in industrial environments. Overall, an armoured capillary tube improves safety, accuracy, and reliability in demanding pressure measurement applications.

A syphon is used in a pressure gauge installation to protect the gauge from high-temperature fluids such as steam. In systems like boilers and steam lines, direct exposure to hot media can damage the internal components of the pressure gauge. The syphon, usually made of coiled or looped tubing, traps a small amount of condensate that forms a water seal. This liquid barrier prevents hot steam from reaching the gauge, reducing thermal stress and extending its lifespan. Additionally, the syphon helps dampen sudden pressure fluctuations, improving measurement accuracy and ensuring safer, more reliable operation of the pressure monitoring system.

A gauge cock is used in a pressure gauge installation to control, isolate, and protect the gauge. It is a small valve fitted between the pressure source and the pressure gauge. Its primary purpose is to allow the operator to shut off the pressure supply when removing, testing, or calibrating the gauge, preventing damage and ensuring safety. The gauge cock also helps in reducing sudden pressure surges that could harm the instrument. Additionally, it enables periodic maintenance without interrupting the entire system. By isolating the gauge, it increases service life, improves measurement accuracy, and ensures safe and efficient operation of the pressure system.
