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.
