Abstract
A magnetostrictive application probe is disclosed wherein the probe includes a preassembled sensor element mounted as an application housing installation as an installable unit. The modular nature allows interchanging with various electronic assemblies, and may be an explosion proof installation.
Claims3
A probe for isolating a magnetostrictive buffered sensor adapted for detecting and measuring the level of liquid in a container, from signal processing circuitry, the signal processing signals from the buffered sensor, comprising:
- a housing enclosing the buffered sensor and having an exterior and interior;
- first means for mounting the buffered sensor in said interior of said housing, including the adaptation for detecting and measuring the level of liquid;
- a second means for permitting the signals from the buffered sensor to be sent to the signal processing circuitry exterior to said housing;
- wherein there is further included a conduit, said conduit mounted in said interior of said housing opposite the buffered sensor, said conduit extending from said interior of said housing to the signal processing circuitry;
- wherein the buffered sensor includes wires located in said interior of said housing, said wires extending interiorly from the buffered sensor through said conduit;
- and
- wherein said first means includes an isolator plug mounted between the buffered sensor and said interior surface of said housing.
