What to Know about Aging and Drift in Type K Thermocouples
Robert Torgerson | Know-how, TemperatureWith repeated exposure to high temperatures, a Type K thermocouple becomes less accurate. Aging is a phenomenon that results in higher-than-accurate temperature readings, while drift results in lower-than-accurate readings. While all Type K thermocouples experience …
Pressure Transmitter Accuracy and Pressure Transmitter Non-Linearity: Not the Same Thing
Robert Lukat | Know-howSometimes, references to pressure transmitter accuracy are actually about the non-linearity of the pressure transmitter’s response. Although accuracy and non-linearity are related, the two terms are not the same and shouldn’t be used interchangeably. The …
The Magnetic Level Indicator Working Principle: Simple and Effective
Patrick McGrath | Know-howThe magnetic level indicator working principle is widely used in level instrumentation. The interaction between float magnets inside the chamber and magnetic flags outside the chamber provide virtually maintenance-free, continuous level information. This type of level …
