Embodiment Construction

[0069] 5 and 6 show a device for temperature control of a process measuring device 1 implemented as an in-line measuring device. The process measuring device 1 is used to detect at least one, in particular physical, measured variable, such as mass flow, density and / or viscosity, of a medium guided in a pipeline and to map it into a measured value signal that instantaneously represents this measured variable; not shown here out of the pipe. An example of an on-line measuring instrument utilizes a vibration-type measuring transducer 10 preferably housed in the measuring transducer housing 7, 6 and utilizes a The measuring device electronics 20 detects the measured variable. The device serves to maintain the temperature of the on-line measuring instrument and thus also the temperature of the medium conducted through the on-line measuring instrument within a predetermined temperature range.

[0070] For guiding the medium, such measuring transducers comprise at least one measuri...

Abstract

The disclosed device comprises at least one heat exchanger (30), which is fixed to an in-line measuring device and which, when operating, is traversed at least temporarily by a temperature-control fluid that transports heat, in addition to fixing means (50, 60), which fasten the heat exchanger (30), in particular in a detachable manner, to the exterior of the in-line measuring device (1). The heat exchanger (30) comprises a curved internal wall (32), configured in the form of a groove or shell, whose surface makes contact with some exterior sections of the in-line measuring device (1), in addition to an external wall that is connected to the internal wall (31). The external wall (31) is connected to the internal wall (32) by means of an edge connection seam (90), which runs along an edge region and is impermeable to the temperature-control fluid and by means of a plurality of internal connection points (80) in the form of dots or rings, which are arranged at a distance from one another in an inner region that is at least partially enclosed by the edge connection seam (90). At least one cavity (H), which conducts the temperature-control fluid and comprises a plurality of interconnecting sections, is configured between the internal wall (32) and the external wall (31), said cavity being integrated into the temperature-control conduit system by means of orifices (33A, 34A) that open into the cavity.

Description

technical field [0001] The invention relates to a device for temperature control of an in-line measuring device having at least one measuring tube which is inserted into a process line and serves to guide a process fluid to be measured. The invention also relates to a heat exchanger suitable for the device and a method of manufacturing the same. Background technique [0002] In industrial process measurement technology, especially in the automation of chemical processes or process operations, process and field measuring instruments are installed on-site, ie brought close to the process, in order to generate measured value signals representing physically measured variables. [0003] For the measurement of physical measured variables, such as mass and / or volume flow, density, viscosity, etc. of the medium conveyed in the pipeline, process measuring instruments are frequently used, which influence the measurement with a physical-electrical measuring transducer and the measuring...
