Beschreibung
Zusammenfassung:	A transducer assembly including a rigid transducer housing. The transducer housing has an interior space and defines a transducer socket and a pressure balancing cylinder. A transducer device is fixedly mounted within the transducer socket. A pressure balancing piston is reciprocably mounted within the pressure balancing cylinder. A pressure balancing fluid and an electronics assembly are contained within the interior space. The electronics assembly is operatively connected with the transducer device. A measurement tool including a tool body and one or more transducer assemblies. The tool body defines one or more pressure balancing body passages extending between mounting pockets in the tool body. The transducer housings define one or more pressure balancing housing passages extending between the interior space and the exterior of the transducer housings. At least some pressure balancing body passages and some pressure balancing housing passages are in pressure communication with each other.
