Embodiment Construction

[0045] figure 1 An exemplary embodiment of a multipoint sensor 1 according to the invention is shown. The multipoint sensor 1 consists of a tubular sheath 3 , which is preferably produced from a metallic material and has a closed end region 31 . In the initial state, the end region opposite the closed end region 31 is open.

[0046] Furthermore, the multipoint sensor 1 has at least two cylindrical spacers 41 , 4 . exist figure 1 In the exemplary embodiment shown, exactly two spacers 41, 4 are used. The spacers 4 , 41 each have a recess 43 in which respectively fastened temperature sensitive members 51 , 52 of the elongated temperature sensors 5 sense one measurement point 2 of the medium temperature profile respectively. The temperature-sensitive components 51 , 52 can be, for example, resistance thermometers or thermal elements.

[0047] The spacers 4, 41 are produced from a material with high thermal conductivity, preferably from a ceramic material such as boron nitride...

Abstract

The invention relates to a multipoint sensor (1) for determining a temperature profile of a medium, the temperature profile consisting of a plurality of measuring points (2, 21), and a method for producing said multipoint sensor, Wherein said multi-point sensor (1) comprises: a tubular sheath (3) having a closed end region (31); n cylindrical spacers (4, 41) produced from a material with high thermal conductivity, wherein n >1, n∈N, wherein the outer diameter (42) of each spacer (4, 41) corresponds substantially to the inner diameter (32) of the sheath (3), wherein the spacer (4, 41 ) is at The interior of the sheath (3) is arranged axially spaced one after the other, wherein each spacer (4, 41) contains a temperature sensitive member (51) for holding an elongated temperature sensor (5) The recess (43) of the , whereby in each case the measurement points (2, 21) of the temperature profile are sensed, wherein, except for the spacer ( 41) each spacer (4) has a through hole (44) for feeding through said elongated temperature sensor (5) fastened to the previous spacer (41) , wherein exactly one elongated temperature sensor (5) is fed through one through-hole (44), and thus the number of through-holes (44) of one spacer (4) corresponds to the number of preceding spacers (41 ); and A filling material (6) arranged between said spacers (4, 41) and surrounding each elongated temperature sensor (5), wherein said filling material (6) has a higher thickness than said spacers (4, 41 ) The thermal conductivity of the material is low.

Description

technical field [0001] The invention relates to a multipoint sensor for determining a temperature profile of a medium, the temperature profile consisting of several measuring points. The invention further relates to a method for producing a multipoint sensor according to the invention. Background technique [0002] Temperature sensors are often used in the field of automation technology, for example to sense the temperature of media in pipelines and / or containers, or in field devices, such as heat sensors for measuring the flow and / or density of media in pipelines. in flow measuring devices. A temperature sensor consists of temperature-sensitive components, such as resistance thermometers or thermal elements, as well as cables, wherein these components are often inserted into a measuring tube. Corresponding temperature sensors and field devices are produced and sold by the applicant. The basic measuring principle of temperature sensors and field devices is known from nume...
