Patent ID: 8044657

Claim:
A probe comprising: a magnetostrictive sensor adapted for detecting and measuring the level of liquid in a container and provide corresponding signal processing signals; a signal conditioner having a buffer circuit configured to condition the signal processing signals to a buffered signal; signal processing circuitry adapted to receive the buffered signal; a housing enclosing said signal conditioner and having an exterior and interior, the housing isolating the magnetostrictive sensor from the signal processing circuitry exterior of the housing; first means for mounting said signal conditioner and at least a portion of the sensor in said interior of said housing; a second means for permitting the buffered signal from the signal conditioner to be sent to the signal processing circuitry exterior to said housing; and a second housing enclosing the first housing and the signal processing circuit, the second housing joined to the sensor so that magnetostrictive sensor, the housing, the signal processing circuitry and the second housing can be carried as a single unit.
