All your temperature sensor calculations From Minco Products, Inc.(Minneapolis), SensorCalc is a free Web-based program that allows you to create temperature and resistance tables for RTD sensors. Options include customizable coefficients for platinum sensors and RTD sensor type options to U.S. and global standards. The program also creates voltage-temperature tables for thermocouple sensors, interchangeability tables for standard RTD sensors and limits of error for thermocouples.
