Electrical Sensors

In this course, students will discuss various types of sensors used on modern drilling rigs, and learn how and why they need to be calibrated.  Time will be spent on sensor terminology and characteristics.  We will do hands on training by hooking up a typical encoder to an oscilloscope and view the output waveforms.  The students will also learn by assembling a circuit using our industrial trainers, how sensors send signals to PLC’s where the inputs are interpreted and sent to outputs.  

All individuals responsible for the installation and maintenance of the various rig electrical sensors
