Abstract

"This report presents the results of an experimental investigation on the effect of an induction field on transducer output. Various types of transducers; strain gages, thermocouples, and thermistors, were used. The changes in the output of these transducers were measured for various induction field conditions.

Measurements must often be made where strong electrical fields are present. Strain gages are used to measure the stresses in electrical machinery. Thermocouples and thermistors used for measuring the temperature of materials undergoing heat treatment with an induction heater are also subjected to an induction field.

The general experimental procedure was the same throughout the investigation. The transducers were placed parallel and normal to the axis of the induction coil. When using the various types of strain gages with an a.c.bridge, the magnitude of the induced strain in all cases was so large that their use in the presence of an induction field is not recommended. Of all thermocouples tested, copper constantan gave best results with errors ranging from 0.63° to 11.2°F. Thermistor errors ranged from 0.32° to 2.4°F"--Abstract, p. ii
