Embodiment Construction

[0064] FIG. 1 shows an ultrasonic sensor device 1 according to the prior art. The ultrasonic sensor device 1 has an ultrasonic transmitter 3 arranged at one end of a transmitter holding element 2 and an ultrasonic receiver 5 arranged at one end of a receiver holding element 4 . The two holding elements 2 , 4 are connected to each other to ensure a constant distance 6 between the ultrasound transmitter 3 and the ultrasound receiver 5 . The ultrasound transmitter 3 and the ultrasound receiver 5 are designed as piezoelectric elements.

[0065] Both the transmitter holding element 2 and the receiver holding element 4 are linearly shaped and together form a fork-like shape.

[0066] The ultrasonic transmitter 3 emits ultrasonic waves into the liquid 10 to be analyzed. The ultrasonic receiver 5 receives ultrasonic waves after the ultrasonic waves have passed through the liquid 10 . The speed of sound in the liquid 10 can be determined from the duration required for ultrasonic wav...

Abstract

The invention relates to an ultrasonic sensor device 1 for analyzing a liquid, the ultrasonic sensor device 1 comprising an ultrasonic transmitter 3 arranged on a transmitter holding element 2 and anultrasonic receiver 5 arranged on a receiver holding element 4, the ultrasonic transmitter 3 and the ultrasonic receiver 5 being arranged at a constant distance 6 from each other. The transmitter holding element 2 and / or the receiver holding element 4 is shaped like a serpentine or a helix. The invention further relates to a refrigeration circuit 12 and to a vehicle 21.

Description

technical field [0001] The invention relates to an ultrasonic sensor device for analyzing liquids, the ultrasonic sensor device having an ultrasonic transmitter arranged on a transmitter holding element and an ultrasonic receiver arranged on a receiver holding element, wherein the ultrasonic transmitter and the ultrasonic receiver The devices are arranged at a constant distance relative to each other. Furthermore, the invention relates to a refrigeration circuit having a compressor, a condenser, an expansion valve and an evaporator, and also to a vehicle. Background technique [0002] Ultrasonic sensors can be used to analyze liquids, such as refrigerants in refrigeration circuits (EP 3376 139A1). An ultrasonic sensor has an ultrasonic transmitter and a corresponding ultrasonic receiver, which are arranged at a certain constant distance from one another. [0003] The ultrasonic transmitter emits ultrasonic waves, and the ultrasonic waves are received by the ultrasonic rece...
