Title: METHOD FOR PRODUCING A SENSING ELEMENT FOR A THERMAL FLOW METER, SENSING ELEMENT AND FLOW METER
Abstract:
The invention relates to a method for producing a probe (10) of a thermal flow meter for measuring the mass flow rate of a medium in a measuring tube, said method having the following steps: introducing a probe core (13) in the form of a material to be melted into a first probe casing (11), the first probe casing (11) having an open first end (21) and a closed second end (22) facing away from the first end (21); melting the probe core (13); quenching the probe core (13) to a temperature below the solidification temperature; attaching a thermoelement (31) to a contact surface (14) of the solidified probe core (13). The invention also relates to a probe obtained according to the production method and to a flow meter comprising the probes according to the invention.
