Bourdon Tube Pressure Gauge - Robust Design For Clean And Non-clogging Media, Low To High Pressure Range

ELASTIC PRESSURE GAUGES INDICATE THE RELATIVE DIFFERENCE BETWEEN THE PRESSURE OF THE MEDIUM AND THE SURROUNDING ATMOSPHERE. THE CONSTRUCTION IS SIMPLE AND ROBUST; NO ADDITIONAL SOURCE OF ENERGY IS NEEDED FOR ITS OPERATION. AMONG THE EXISTING TYPES OF SENSING/ ELASTIC ELEMENTS.
* BOURDON TUBE : THESE ARE USED FOR MEASUREMENT OF PRESSURE AND VACUUM AND ARE SUITABLE FOR ALL CLEAN AND NON-CLOGGING LIQUID AND GASEOUS MEDIA. THE BOURDON TUBE IS A THIN WALLED TUBE OF OVAL CROSS SECTION WHICH MAY BE OF 'C' FORM OR SPIRALLY WOUND. THIS TUBE EXPANDS WHEN PRESSURE IS APPLIED INTERNALLY; THIS EXPANSION IS CONVERTED INTO ROTATION OF A CONCENTRIC POINTER WITH A GEAR MOVEMENT. THE READING INDICATED ON A DIAL BY THE POINTER IS PROPORTIONAL TO THE PRESSURE APPLIED. C-TYPE BOURDON TUBES ARE USED FOR LOW PRESSURE RANGES AND HELICAL/ SPIRAL TUBES FOR HIGHER PRESSURE RANGES.
