The discrete outputs of a safety system are the principle means that process safety instrumented systems interact with the real world. But today's discrete output modules offer far more than their predecessors.
In this article from Control Design's sibling publication Control, John Rezabek explains that although today's output modules offer more capability to detect more subtle changes, they only bear fruit if they're routinely monitored.
This paper examines highly sensitive piezoelectric sensors for precise vibration measurement which is critical in semiconductor production to prevent quality and yield issues....
Motor encoders are rotary encoders adapted to provide information about an electric motor shaft's speed and/or position. Like rotary encoders, motor encoders are most commonly...
