Profile: Spectrum Sensors & Control Inc. is a manufacturer of precision, co-molded conductive plastic potentiometers, and position sensors & transducers. We are an ISO 9001:2000 certified company. Our product line includes element segments and wiper assemblies, rotatory potentiometers, linear potentiometers, motorized potentiometers, hollow-shaft, and value added assemblies. We also offer probes and assemblies, PTC & NTC thermistors, and sensors. Our probes and assembly ruggedized temperature sensor is designed to offer a robust solution for monitoring temperature in difficult environments. This product is especially useful in high moisture applications where the sensor is subjected to continuous freeze cycles. Our disc style thermistors are ideal for use in those applications where rugged design are desired. This thermistors are available as coated & uncoated types, and in a variety of resistance values, curves & tolerances to suit a wide variety of applications.
