As technology advances, process automation professionals face a myriad of ways to connect instrumentation and final control elements to their control systems. Some ways include direct wiring, remote I/O, multiplexors, locally mounted transmitters, HART-enabled transmitters, Foundation fieldbus, and IEC 62591 WirelessHART. When it comes to direct wiring, some instrumentation, such as temperature measurement devices, have […]
Instrumentation professionals have many choices in technology when it comes to measuring pressure, temperature, level, and flow. Over time, experience teaches which technologies work best for which applications. For those new to the instrumentation and process control world, the choices can seem overwhelming. From a temperature measurement view, Emerson’s Ashleigh Hayes has a great article […]
I often learn of developments within our organization from the global trade press. So is the case today when I read a tweet from Ireland’s @ReadoutSignpost (Eoin Ó Riain’s) tweet: Industry-first measurement validation diagnostic on Rosemount temp transmitter #PAuto #Safety http://t.co/GvPN26j9 The link goes to Eoin’s Read-out Instrumentation Signpost blog, where he shares how the […]
Are you among the process automation professionals who consider temperature control loops among the most difficult to control in your plant? If so, then Modeling and Control blog’s Greg McMillan‘s recent article in Quality Digest may be for you. The article, Don’t Sweat That Temperature Loop, looks at the various types of temperature sensing technologies, […]
At last week’s Emerson Exchange, John Rezabek of ISP presented Wireless or Fieldbus? You might recall John from his columns in Control magazine and on the ControlGlobal.com site. He presented a cost comparison for a plant expansion considering Foundation fieldbus instruments versus WirelessHART-based ones. John values the digital integration of field devices, which both technologies […]
