Passenger safety was foremost, correcting load shifts in each car to maintain stability of each. Reliability and availability were important; downtime is lost revenue, so…
MartinCSI designed a system to collect machine data, store it on a cloud server, and provide HFI with direct access to the database. The implementation…
Like many manufacturers, HFI was ready to explore the advantages of implementing IIoT capabilities and data analysis. IIoT implementations tout the ability to identify trends,…
While conceptually simple, step tests can be a challenge to automate. The results will be skewed if a disturbance happens to intrude on the process…
The most basic autotuners simply automate the manual tuning procedures an operator might otherwise perform when commissioning a loop: force a change in the control…
Although the industrial automation industry has, for the most part, adopted the proportional-integral-derivative (PID) algorithm as the de facto standard for closed-loop process control, the…
The most common optical sensor options are photoelectric—diffuse, reflective, and through beam. Laser sensors and fiber-optic sensing units also fall under the optical sensor category.…
Like pressure and vacuum sensors, flow sensors are specified by flow range, size, and setpoint variability. They can be ordered with on sensor display options.…
Ensure the pressure or vacuum sensor will accommodate the pressure range required as measured in pounds per square inch for imperial measurement and bar for…
Inductive proximity sensors use Faraday’s law of induction to indicate an object’s presence or an analog output position. The most critical aspect of selecting an…
