Sensors Used in Machine Tools

In this section, several types of sensors which are usually used in machining tools will be introduced. The sensors will be classified by the stimulus:

  • Displacement
  • Capacitive Sensor
    Inductive Sensor (LVDT)
    Magnetic Sensor (Hall Effect)
    Optical Sensor 
    Ultrasonic Sensor

  • Velocity and Acceleration
  • Eletromagnetic Velocity Senor
    Capacitive Accelerometer
    Piezoelectric Accelerometer

  • Force and Strain
  • Strain Gauges
    Piezoelectric Force Sensor
    Tactile Sensor

  • Pressure
  • Mercury Presure Sensor
    Bellow, Membranes, and Thin Plates
    Piezoresistive Sensor

  • Acoustic
  • Condenser Microphone
    Electret Microphone

  • Temperature
  • Thermoresistive Sensor
    Thermoelectric Contact Sensor
