A small diameter proximity coil for use in proximity sensors to sense imbalance in rotating machinery which has a coil of less than 0.3 inch diameter is constructed of a silver/palladium alloy of 89% silver and 11% palladium. This provides for, because of the inherent balancing out of AC and DC resistance changes, temperature errors of less than 10% over a wide temperature range of operation.
