摘要:
A microwave sensor assembly includes a signal processing device for generating at least one microwave signal that includes a pattern of frequencies and at least one probe coupled to the signal processing device. The probe includes an emitter configured to generate an electromagnetic field from the at least one microwave signal, wherein the emitter is detuned when an object is positioned within the electromagnetic field such that a loading signal is reflected from the emitter to the signal processing device.

A microwave emitter for use in a microwave sensor assembly that includes an emitter body includes a first arm that extends radially outward from the emitter body. The first arm is at least partially non-linear and includes at least one peak and at least one trough. The microwave emitter also includes a second arm that extends radially outward from the emitter body. The second arm includes at least one peak and at least one trough. The first arm and the second arm generate an electromagnetic field when at least one microwave signal is received.
摘要:
A proximity sensor assembly with a sensing element having a substrate and an antenna pattern disposed on one or more planar surfaces of the substrate is disclosed. The cable is fed substantially parallel to the planar surfaces of the substrate and is attached to the side surface of the substrate, such that the cable is oriented substantially perpendicular to the direction of the electromagnetic field emitted from the sensing element.

A probe for use in a sensor assembly includes an sensing element body and an sensing element coupled to the sensing element body. The sensing element is at least partially capacitively coupled to a signal processing device. The sensing element generates an electromagnetic field when at least one signal is received, and a loading is induced to the sensing element when an object is positioned within the electromagnetic field.

A microwave sensor assembly includes at least one probe including an emitter configured to generate an electromagnetic field from at least one microwave signal. The emitter is also configured to generate at least one loading signal representative of a loading induced within the emitter by an object positioned within the electromagnetic field. The microwave sensor assembly also includes a signal processing device coupled to the at least one probe. The signal processing device includes a linearizer configured to generate a substantially linear output signal based on the at least one loading signal.

A microwave probe for use in a microwave sensor assembly includes an emitter body and an emitter coupled to the emitter body. The emitter includes a first portion, a second portion, and a connecting portion coupling the first portion to the second portion. The first portion and the second portion generate an electromagnetic field when at least one microwave signal is received, and a loading is induced to the emitter when an object is positioned within the electromagnetic field.
