MPS measuring station D – Analog measurement technology in quality processes

MPS measuring station D – Analog measurement technology in quality processes

The MPS measuring station D tackles a number of topics, including how to record and process analog and digital signals. The station also provides insight into how pneumatic actuators work and are used, and how actuators are calibrated.

The station takes workpieces out of the ongoing process in order to place them on a measuring table and measure their height. The conveyor module transports the workpieces to the measurement point. The rotary lifting module moves a workpiece into the measuring position. The diffuse sensor measures the height of the workpiece. Depending on the result of the measurement, an electric quarter-turn actuator either moves the workpiece onto a material slide or places in on the conveyor.

Fiber-optic through-beam sensors and opto sensors monitor the material flow on both conveyors. The conveyors can be used in both directions.

The diffuse sensor supplies either an analog or a digital output signal, as required. The module can thus be used for various levels of training. The binary switching output can be adapted to the measurement requirement and the signal type by means of teach-in programming.

The rotary lifting module uses an electric quarter turn actuator and a pneumatic gripper to automate the measurement task and take random samples from the process.


  • The highly modular nature of the station makes it incredibly versatile and allows it to be used for many different types of project work.
  • The station can be used individually or together with other stations at various points in a system or process.
  • With the aid of this station, students will develop basic knowledge of measurement and sorting processes and of how to control a conveyor.
  • The students will also learn the basics of sensor signal recording and processing and how to program standardizations for the calibration of actuators.
