All measuring devices lose accuracy over time. Therefore, reliable readings require a regular schedule of calibrations. The particular conditions and needs of each application will determine when it is time to recalibrate a measuring instrument. Time isn’t …
Three specific types of errors have a negative impact on pressure sensor accuracy. This easy-to-understand video from WIKA explains the difference between zero-point errors, span errors, and non-linearity. Inaccuracies in pressure instrumentation occur when the …
Refinery operators who work with fixed bed catalysts place a high value on temperature accuracy, but they also don’t want to waste time by taking unnecessary temperature readings. Thus, to better understand any radial temperature differences that may exist during …
With 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 …
A thermowell is a protective housing for a thermometer used to provide temperature readings for an industrial process. Given that process media in many industries are corrosive, abrasive or under high pressure, a thermometer is placed inside a thermowell so the …
