Profile: U. S. Sensor Corp. is a manufacturer of thermistors, thermistor probes, and resistance temperature detector assemblies. Our thermistors are thermally sensitive resistors whose prime function is to exhibit a large, predictable, and precise change in electrical resistance, when subjected to a corresponding change in body temperature. We also provide negative temperature co-efficient thermistors which exhibit decrease in electrical resistance when subjected to an increase in body temperature, and positive temperature co-efficient thermistors that exhibit an increase in electrical resistance when subjected to an increase in body temperature. We offer thin film platinum resistance temperature detector which consists of a thin film of platinum deposited on a ceramic substrate, and a glass coated platinum element. This provides a virtual linear relationship between temperature & resistance, and is capable of withstanding temperatures ranging from -50°C to +500°C. Our ultra precision interchangeable thermistors are stable devices designed specifically for temperature sensing & control applications. They are particularly suited for uses where their precision interchangeability eliminates the necessity for individual circuit calibration.
