Getting to the Bottom of a RTD Sensor Reading Delay
Adam DeLanceyThe process engineers at a major chemical manufacturer were stumped. They were regularly getting very poor response times from their process temperature sensors and simply could not figure out why. The response times to temperature changes were consistently close to 30 …
WIKA’s ScrutonWell® Reduces Vibration to Provide Accurate, Rapid Thermometer Response Time
Adam DeLanceyA 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 …
4-Wire RTDs vs. 3-Wire RTDs
Adam DeLanceyThe electrical resistance of some materials, such as platinum, copper, and nickel, differs at different temperatures. Resistance temperature detectors (RTDs) take advantage of this property to assess temperature in a variety of commercial and industrial applications. …
When to Use a 3-Wire RTD
Adam DeLanceyRTDs (resistance temperature detectors) are the most common, most versatile temperature sensors in industrial and process applications. They are stable, have good repeatability and work well within a wide range of temperatures. The electrical resistance of some …
