Title:
TEMPERATURE SENSOR AND THERMAL FLOW RATE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/060186
Kind Code:
A3
Abstract:
The invention relates to a temperature sensor having a housing (1), comprising a housing body and a housing chamber, in which housing chamber two temperature sensor elements are arranged at each end, which temperature sensor elements are in particular formed as thin-film resistance thermometers (4 or 5), wherein one of the temperature sensor elements can be heated, wherein at least one connection wire (23) leads from each temperature sensor element, which connection wire is connected to a printed circuit board (25), wherein the printed circuit board (25) is arranged in the housing chamber (1), wherein the printed circuit board (25) is positioned in said housing chamber by means of a latch connection (28), wherein a connection wire (23a) of a first temperature sensor element is routed in a strain-relieved manner in a first direction through the printed circuit board (25) and is connected to the latter, wherein the housing chamber has at least one first elastic body for routing the connection wire (23) and/or wherein the printed circuit board (25) is arranged in the housing chamber, wherein the printed circuit board (25) has a first number of material cut-outs, in particular holes, for the connection of connection wires and/or cables and a second number of material cut-outs, in particular holes, for reducing the thermal expansion of the printed circuit board, and a thermal flow rate measurement device.
