Zusammenfassung:	The capacitive sensor assembly (2) for a testing device (1) for testing an elongated textile sample comprises at least one measuring electrode as part of a measuring capacitor for the capacitive testing of the sample, and an electrical circuit that is electrically connected to the at least one measuring electrode. The capacitive sensor assembly (2) also comprises a temperature sensor for measuring a temperature of at least one part (4) of the capacitive sensor assembly (2), and a controllable electro-thermal converter (5) that is thermally connected to the at least one part (4) of the capacitive sensor assembly (2). In this way, the at least one part (4) of the capacitive sensor assembly (2) can be regulated to a desired temperature value, such that the capacitive sensor assembly (2) measures in a substantially stable manner and without temperature drift.
