Servo Motion Control
In servo motion, a feedback sensor - usually encoder - is used to continuously measure position and speed of motor to correct motor speed. By using feedback sensor, we can get very accurate results. Most servo motors now have on-board 'Motor Encoder'. However, additional encoders could be placed on the actual mechanical axis to compare against actual line...
Machine Safety Integrity Level SIL
A quick google search tells us that Sil level is about probability of failure but what does it mean in terms of process engineering? I have written this brief article focusing on how expression SIL and IEC 61508 applies to our field of work.
What is SIS
If an instrument is SIS rated i.e. Safety Instrumented System,...
