1. A sensor assembly comprising:
a housing comprising a tubular portion, a membrane, a cable, an ultrasonic sensor, and a further sensor;
wherein the tubular portion comprises a first end;
wherein the tubular portion connects to the membrane at the first end of the tubular portion;
wherein the ultrasonic sensor comprises a piezoelectric transducer and a wrap-around electrode;
wherein the piezoelectric transducer comprises a first side and a second side, the second side of the piezoelectric transducer being disposed opposite the first side of the piezoelectric transducer;
wherein the first side of the piezoelectric transducer is mounted to the membrane;
wherein the wrap-around electrode comprises a first portion and a second portion, the second portion of the wrap-around electrode connecting to the first portion of the wrap-around electrode;
wherein the first portion of the wrap-around electrode is arranged at the first side of the piezoelectric transducer, between the piezoelectric transducer and the membrane, and the second portion of the wrap-around electrode is arranged at the second side of the piezoelectric transducer;
wherein the second side of the piezoelectric transducer, the second portion of the wrap-around electrode, and the further sensor connect to the cable; and
wherein the tubular portion comprises inner walls and the further sensor is arranged in between the inner walls of the tubular portion.
