Thermocouple Type K | Type K Thermocouple | Chromel/Alumel ...

A Type K thermocouple can be connected to a voltmeter for simple data collection. In this case, the output is a voltage, and the reader has to convert the voltage level to temperature using a conversion formula. To record data, the thermocouple can be connected to a data logger or a data acquisition system to store collected data. In these cases, a conversion circuit or a software operation can be used to calculate the temperature …
