Level Control System
The Level system consists of a reservoir water tank, a variable speed pump, a pressure-based level sensor, and clear process vessel with a scale. A proportional valve provides the process vessel drain ..
Servo/pendulum motor control system
Item Number:
CT9513
The Servo Pendulum system is part of the Matrix Process Control range of products.
This unique system allows students to understand the control of motors in two respects: to control the speed of a motor – a servo control system - and to control the position of a motor’s rotor – an inverting pendulum. One piece of equipment covers both problems.
The system consists of a powerful DC motor mounted on a rugged frame. A disc with captive nuts is attached to the DC motor and students can screw in 100-gram weights to different parts of the disc to alter the system's characteristics. A single weight at 0 degrees forms an inverting pendulum.
The system includes full control and data-logging hardware, which is USB, Bluetooth, LAN/Wi-fi compatible. Three software applications allow students to understand Manual control, On/Off control and PID control. The applications allow all parameters to be set, show a graphical representation of the performance of the system and allow data to be logged to a file for further analysis.
The system is shipped with a full API making it compatible with MATLAB or LabVIEW.
A full suite of worksheets, teacher’s notes and reference documentation is supplied.
