Temperature transmitters convert the input signals from electronic temperature sensors, such as RTDs and thermocouples, into digital or analog output signals. Safety and efficiency require selecting the right transmitter for specific applications. Temperature …
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 …
