Principle of important structures and pressure-pressure gauge 1. stress gauge's major structure The overflow hole: in case of emergencies with the Bourdon tube bursts, the internal pressure might be released towards the outdoors globe by means of the overflow hole, stopping glass panels burst. Note: as a way to maintain normal performance of overflow hole, leave no less than 10MM space necessary behind the table, does not reform or plug the overflow hole.
Pointer: also for the common pointer to pointer is also optional. Glass panel: moreover for the normal glass, particular glass supplies, which include glass, non-reflective glass is also optional. Classification: normal (common), steam with medium (m), heat (h), vibration-proof variety (v), steam-resistant vibration-type (MV) heat-resistant vibration mode (HV). Disposition: oil/water remedy at the time of manufacture-ban-ban to take away water or oil residue in the wetted part. Exterior designation: Shell colors besides typical colour, be indicated. Throttle valve (optional): so as to reduce the stress, throttle valve installed at the entrance to stress. two. the principle of pressure
Pressure sensitive element within a table by table (Bourdon tube, diaphragm, bellows), elastic deformation, then the conversion facility will stress deformation movement from the table into a pointer, result in hands to show pressure. Bourdon tube bursts when emergencies occurred, the internal stress are going to be released for the outdoors planet by way of the overflow hole, stopping glass panels burst. Note: to be able to preserve regular performance of overflow hole, follow the table for no less than 10MM space, not reform or plug the overflow hole. Furthermore for the standard pointer to pointer is also optional. (Or set the maximum zero adjustment pointer pointer pointer) Source:http://www.zhaohuisensor.com/
