Various embodiments may include a method for producing an ultrasound sensor to detect the filling level and/or the temperature of a fluid in an internal combustion engine comprising: arranging an electronics system of the ultrasound sensor in an injection molding die; and encapsulating the electronics system by injection molding with a thermoplastic material and thereby forming a housing for the electronics system; and removing the encapsulated electronics system from the injection molding die. The housing includes a functional section to fulfill a predetermined function.

Ultrasound sensor

A filling level transmitter includes a sound-conducting tube and a filling level sensor. The filling level sensor has: a housing including a ceramic substrate and a metal lid soldered to the substrate, an ultrasonic transceiver arranged in the housing and having a sound-outputting region, the ultrasonic transceiver being connected by at least the sound-outputting region to the substrate, and sensor electronics arranged in the housing.

Ultrasound level transmitter

An ultrasound sensor arrangement for determining a fluid level includes an elongated housing with a lid and a floor, and a measuring chamber in the housing, in which a fluid has the same level as the fluid outside the measuring chamber, and an ultrasound transmitter/receiver on the floor within or outside the housing in the area of the measuring chamber. Transmitted sound signals from the ultrasound transmitter/receiver reflect from the fluid surface and are received by the ultrasound transmitter/receiver to determine the fluid level from the signal transit time. At least one further chamber is arranged at least partially in front of or around the measuring chamber. The outermost chamber forms the inlet chamber. The several chambers are connected to each other for fluid flow.

Temperature stability at the temperatures prevailing in a motor and stability that is required over an entire temperature range are provided by an attenuating mass. This enables continuous use at temperatures of approximately 150&#xb0; C. while providing ultrasonic attenuation at low temperatures.
