摘要： An orifice plugging sensor for a flow-rate controller having an orifice, comprising a memory (M) in which is stored reference pressure decrease data Y(t) about the upstream-side pressure P1 measured when the flow rate is changed from a high preset flow rate QSH to a low preset flow rate QSL under the condition that an orifice (2) does not plug, a pressure sensor (14) for measuring pressure decrease data P(t) about the upstream-side pressure P1 measured when the flow rate is changed from the high preset flow rate QSH to the low preset flow rate QSL under the condition that the orifice is in an actual state, a central processing unit (CPU) for comparison operation of the pressure decrease data P(t) and the reference pressure decrease data Y(t), and an alarm circuit (46) for giving an alarm of a plugging when the pressure decrease data P(t) differs from the reference pressure decrease data by a predetermined degree.

摘要： A pressure detector mounting structure capable of preventing a diaphragm from being deformed by a stress acting on a diaphragm type pressure detector and output characteristics and temperature characteristics from being varied when the pressure detector is incorporated in a fixture provided in a piping or equipment, wherein the pressure detector formed by fixedly combining a diaphragm base having a diaphragm with a sensor base incorporating a sensor element operating according to the displacement of the diaphragm is inserted into an inserting hole through a gasket and pressed air-tight fixedly from the upper side using a pressing member, the pressing member and the gasket are brought into contact with the upper and lower surfaces of a main body of the diaphragm base, respectively, and a shallow groove is formed in ring-shape in the lower surface of the main body on the inner side of a part in contact with the gasket so as to off set a deformation produced by a pressing force from the pressing member through the shallow groove.
