PRESSURE GAGE, PRESSURE CUFF MOUNTED WITH THE GAGE AND THEIR USING METHOD

摘要

PROBLEM TO BE SOLVED: To allow the vicinity of an inspection window to emit a light by laminating a light reflective label color coded to be distinguished on the surface of a scale core or charging a luminous body in the core made of transparent synthetic resin. ;SOLUTION: The pressure gage 1 comprises a diaphragm 7 to be deformed to be expanded upon reception of a pressure, a scale core 5 disposed on the diaphragm 7, a spring 3, and an inspection window 4 mounted between housings 2 and 8 (moving position of the core 5). A light reflective color coding label 6 color coded to be distinguished is laminated on the core 5. Since the core 5 is color coded by laminating a light reflective film, the pressure can be easily confirmed by emitting a light in a dark environment even if it is not approached near at hand. Further, when a pressure cuff is used, the core 5a can be illuminated from the interior.;COPYRIGHT: (C)1997,JPO
