  • Sensor arrangement and method for monitoring a circulation pump system
    Patent number: 11867186
    Abstract: A sensor arrangement is for monitoring a circulation pump system (1) which includes at least one pump (3). The sensor arrangement includes a first vibration sensor (5) installed at a first pump part (11) of one of the at least one pump (3) and a second vibration sensor (7) installed at a second pump part (13) of the pump (3) and an evaluation module (9). The first pump part (11) and the second pump part (29) have a distance to each other. The evaluation module (9), is configured to discriminate between at least two of k?2 different types of faults based on comparing first signals received from the first vibration sensor (5) and second signals received from the second vibration sensor (7).
