Abstract: An industrial process transmitter includes a main housing, a sensor body, and a flange member. The main housing contains transmitter circuitry and includes a first threaded portion. The sensor body includes a process sensor and a second threaded portion in threaded engagement with the first threaded portion. One of the first and second threaded portions includes a threaded cylindrical projection, and the other includes a threaded cylindrical bore. The flange member is received within a groove of the projection. Movement of the sensor body relative to the housing along an axis of the bore is restricted to an axial distance through engagement between the flange and the first or second threaded portion that includes the threaded cylindrical bore, and engagement between the main housing and the sensor body. Rotation of the sensor body relative to the housing about the axis is limited by the axial distance.

Abstract: The present disclosure is provided with a measuring element (M) and a measuring device. The measuring element includes a base body, a diaphragm and a permeation resistant layer, the diaphragm is fixedly connected to the base body, with a sealed cavity being defined between the diaphragm and the base body. The permeation resistant layer is arranged on an inner side surface, facing the sealed cavity, of the diaphragm, and extended continuously on the inner side surface of the diaphragm at least beyond a connection region of the diaphragm with the base body. The measuring device includes the measuring element (M).
