Temperature is a critical factor in almost all manufacturing and refining processes. As such, process plants have developed a variety of useful technologies related to accurate temperature measurement and control in their operations . Heat tracing is one well-known …
Petrochemical plants use steam crackers to convert ethane into more useful ethylene. This energy-intensive process calls for maintaining very high temperature measurement within a relatively narrow range. The conversion of ethylene is poor if the temperature is …
Thermocouples are rugged and respond quickly to temperature changes. When sheathed, these temperature measurement instruments are extremely resistant to vibration, mechanical stresses, and aggressive/corrosive media. Because they’re small and highly bendable, …
Thermocouples are among the most popular temperature measurement instruments in industrial applications because of their versatility and ease of use. However, measurement errors can occur. This article discusses the six most common causes of thermocouple errors. …
A false trip is when an instrument error, rather than an actual problem, sets off (“trips”) a safety alarm. All plant operators want to avoid false trips, especially the ones that lead to a full process shutdown – a very expensive scenario. WIKA’s SIL III …
