DEVICE FOR DETECTING PRESSURE FOR AUTOMATIC GREASE LUBRICATOR CAPABLE OF AVOIDING OVERLOAD

摘要

PURPOSE: A device for detecting pressure for an automatic grease lubricator is provided to prevent the overload of the automatic grease lubricator. CONSTITUTION: A pressure detecting unit(10) and a circuit board(70) are mounted to a main body(80). A piston(20) has an oil ring(21) installed at a piston guide and supported by a spring(31). A ground unit(23) is formed at the piston, and is connected to a ground switch(71) in the circuit board. A body cover(90) is coupled to the top of the main body, and has an oil pressure indicating unit(91), a contact indicating unit(92), and a lamp indicating unit(93).
