Title: Sydney K Tew: Innovator in Transducer Technology

Introduction

Sydney K Tew is a notable inventor based in New Baltimore, MI (US). She has made significant contributions to the field of transducer technology, holding a total of 4 patents. Her innovative designs have advanced the capabilities of position and temperature sensing devices.

Latest Patents

Among her latest patents is a transducer designed for providing a position signal and temperature measurement. This two-wire transducer and its associated circuit processes an output voltage to produce a first signal proportional to the position of a non-contacting movable core and a second signal proportional to the temperature of operation. The circuit includes an excitation source that provides a fixed frequency sinusoidal constant current across the transducer coil. Additionally, first and second demodulator circuits extract position and temperature signals from the voltage developed across the coil, allowing both types of information to be conveyed through a single device over a single pair of leads.

Another significant patent is the movable core position transducer. This two-wire linear transducer consists of a high permeability finite length core positioned with respect to a continuously wound variable pitch coil. The core is displaced from its initial stroke position to the opposite end of the coil, producing an output signal that varies with displacement. The coil is energized by a constant alternating current source, and its winding configuration generates an alternating output voltage. The imaginary component of this voltage varies linearly and continuously in amplitude, reflecting the movement of the ferrite core.
