TEMPERATURE SENSOR DEVICE FOR MEASURING A TEMPERATURE OF A LIQUID FLOWING THROUGH A PUMP

The invention relates to a temperature sensor device (6) for measuring a temperature of a liquid flowing through a pump (1). The temperature sensor device comprises a temperature sensor (7), at least one connector (10) configured to electrically connect the temperature sensor to at least one printed circuit board (5) of the pump, and a sensor cup (11). The sensor cup comprises a circumferential cup wall (12) extending between a closed end (13) and an open end (14) of the sensor cup. The cup wall surrounds an inner cavity (15), and the sensor cup is dimensioned and shaped for having the closed end arranged in physical contact with a rotor can (3) of the pump during use, such as extending in a liquid tight manner through an opening (21) in a rotor can. A heat transfer medium (16) is present in the inner cavity. The temperature sensor and the sensor cup are mutually arranged with the temperature sensor extending into the heat transfer medium so that during use of the temperature sensor device, the temperature sensor can measure the temperature of the liquid via the heat transfer medium.
