A G R E AT E R M E A S U R E O F C O N F I D E N C E How to Select the Right Temperature Sensor By: Dale Cigoy Title: Senior Applications Engineer Keithley Instruments, Inc. Cleveland, OH can handle this temperature range, and Introduction interfaces. Due to the scope of this article, the type K is the most general purpose The most widely measured physical such sensors will not be covered in detail. thermocouple for such applications. On parameter is temperature. Whether the other hand, a ceramic firing kiln can in process industry applications or in Selecting a Temperature Sensor be many hundreds of degrees C. A type N laboratory settings, accurate temperature There are several considerations would be good for the higher temperature, measurements are a critical part of success. when selecting a temperature because of their stability and resistance Accurate temperature measurements are sensor. First, consider to high temperature oxidation. On the needed in medical applications, materials the type of application. What is the other end of the scale, superconducting research in labs, electrical/electronic device to be measured? Is it ambient air devices achieve superconductivity at component studies, biology research, temperature in a room or enclosure? An very low temperatures, around several geological studies, and electrical product electronic component with plastic or metal Kelvin (or just above absolute zero or device thermal characterization. packaging that may or may not have high
