Sensors & Simple Control Systems
Build intuition for what each industrial sensor physically does, and how it fits inside a basic feedback control loop. Each lesson opens with a short animation that shows the working principle, followed by a plain-English explanation and a list of the common types you'll meet on the job.
Open vs closed loop, feedback, setpoint, actuator, transducer.
Strain gauge, piezoelectric, piezoresistive, capacitive, optical.
Thermocouple, RTD, thermistor, infrared, bimetallic.
Hall effect, optical encoder, magnetic pickup, tachogenerator.
Differential pressure, turbine, magnetic, ultrasonic, Coriolis, vortex.
Float, capacitive, ultrasonic, radar, hydrostatic, conductivity.
Diaphragm, piston, bourdon, differential; setpoint & deadband.
The goal is to build intuition for what each sensor physically does — not to memorise specs. The animations stay short and the maths stays out of the way.
