Title:
PROCESS TRANSMITTER HAVING A ROTATABLE COUPLING
Document Type and Number:
WIPO Patent Application WO/2019/041122
Kind Code:
A1
Abstract:
An industrial process transmitter(100) includes a main housing(120), a sensor body(122), and a flange member(150). The main housing(120) contains transmitter circuitry(114) and includes a first threaded portion. The sensor body(122) includes a process sensor(112) 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(130), and the other includes a threaded cylindrical bore(132). The flange member(150) is received within a groove(152) of the projection(130). Movement of the sensor body(122) relative to the housing(120) along an axis(126) of the bore(132) is restricted to an axial distance(170) through engagement between the flange(150) and the first or second threaded portion that includes the threaded cylindrical bore(132), and engagement between the main housing(120) and the sensor body(122). Rotation of the sensor body(122) relative to the housing(120) about the axis(126) is limited by the axial distance(170).
