PRESSURE GAUGE CAPABLE OF INDICATING A PROPER PRESSURE RANGE, CAPABLE OF ARBITRARILY SETTING A PROPER PRESSURE RANGE

摘要

PURPOSE: A pressure gauge capable of indicating a proper pressure range is provided to evaluate the appropriateness of working pressure regardless of a skill level of an operator by easily and visually confirming whether pressure is proper or not.;CONSTITUTION: A pressure gauge capable of indicating a proper pressure range comprises an indication needle(120) and a scale board(130). The indication needle is arranged in a receiving unit(112) of a case, thereby rotating according to the pressure of equipment or a device. Pressure scales that the indication needle indicates are marked on the scale board. The receiving unit of the case comprises a proper pressure range plate(150), an over-pressure indicating plate(160), and a low pressure indicating plate. The proper pressure range plate indicates a proper pressure range. The over-pressure indicating plate indicates an over-pressure range exceeding a normal pressure range. The low-pressure indicating plate indicates a low-pressure range below a low pressure range.;COPYRIGHT KIPO 2013
