Motion Control Learning System Single Axis applies to a wide range of industries that need to meet market demands for greater system throughput and improved output quality and precision. Some of these industries include automotive, energy, medical, petroleum, printing, and packaging. Motion Control Learning System Single Axis is used where conventional motor control, using discrete inputs and outputs, cannot achieve the accuracy needed to produce a product. A motion controller sends acceleration and velocity commands to each motor to control its speed, torque, and rotor position. At the same time the motion controller monitors these parameters and adjusts the output as needed to create a legible color image on the page. A good example of motion control is an offset printing press that uses four motors to print four separate colors on a page and another motor to turn the feed roll. Motion Control Learning System Single Axis is self-contained and teaches students to control one axis. It allows students to learn industry-relevant skills including how to create, navigate, configure, operate, maintain, and apply motion control systems. Motion Control Learning System Single Axis teaches the skills required to understand and maintain the sophisticated applications so commonly found in modern industry. The motion control action may be as simple as opening and closing a valve or as complex as controlling multiple axes on a CNC machine. Motion Control Learning System Single Axis includes a tabletop workstation, motion controller with control programming software, tensioning kit, synchronization kit, registration kit, timing kit, communication cables, lockout/tagout kit, student curriculum, and instructors assessment guide. The Motion Control Learning System Single Axis system provides instruction in motion control for a single axis system, including set-up, operation, programming, and control.

Biodiesel Process Trainer PLC Controls provides students the opportunity to gain real operating experience focusing on all aspects of biodiesel production the chemical process, control strategy, and management of the chemical process. The Biodiesel Process Trainer is a pilot-scale plant that demonstrates both batch and semi-continuous conversion of vegetable oil feedstock into biodiesel. The Biodiesel Process Trainer has instrumentation to provide for control of all process flows, temperatures and levels.
Function:
The rate of reaction is influenced by several factors including temperature and degree of mixing. The Biodiesel Process Trainer is designed and built for instructional use and includes many student-friendly features. The conversion of triglycerides into biodiesel is normally performed by base-catalyzed conversion. This reaction takes place at modest conditions of temperature and pressure and can produce conversion rates over 98%. This highly flexible process trainer incorporates various commercially available mixing technologies and process configuration options to allow for the comparative analysis of the technologies currently available in the biodiesel industry. The main reaction vessel is constructed from industrial glass allowing the students to visually monitor the trans-esterification process.
The simple heating circuit with one subcircuit contains two flat radiators and is controlled by a temperature-led controller. A three-way mixing valve is the actuator. A complete domestic heating system can be set up using the trainer together with a hot water generator, Hot water passes through the radiators and heats the room air. It contains two heating circuits. A simulator is supplied for varying the outside temperature. The heating circuit with two subcircuits contains four radiators and two heating controllers. Both heating circuits are equipped with commercially available heating technology control devices. Solenoid valves enable control of the heat distribution in the two subcircuits. Each heating circuit contains a circulating pump.

Pressure Control And Regulation Study Unit makes it possible to analyse the behavior of a control loop where the controlled quantity is the pressure of the air ina tank. Pressure control is one of the main problems encountered in factory automation and process control. Students can examine the effects of the different control parameters on the performance of the control chain and on the stability of the system; furthermore, they can become familiar with the components commonly adopted in modern industrial applications, as the system is entirely made of industrial quality components. With this trainer, all the tests can be performed through a Personal Computer and a special software for Windows. This makes the problem of choosing the most suitable control technique very interesting. Compared to other quantities such as the level or the temperature the pressure varies as a function of the regulating signal in a very quick way.

The SCR Speed Control Learning System features heavy-duty components like an SCR speed control unit, DC shunt wound motor, and fuse block to give learners real-world practice on SCR speed control skills such as connecting and operating a motor with SCR half-wave speed control, measuring the performance of SCR half-wave speed control, and troubleshooting an SCR speed control circuit. SCR Speed Control Learning System adds to the Electronic Motor Control Learning System to teach variable speed motor control of DC electric motors using Silicon Controlled Rectifier (SCR)-based circuits. These hands-on skills are carefully interwoven with world-class SCR speed control curriculum so that learners understand both the theoretical and practical knowledge that they'll need to be successful. SCRs convert AC voltage into a DC voltage in order to provide efficient variable speed control of DC motors and are widely used within industrial applications such as cranes and machine tool spindles.

The simulator takes into consideration all these components, by analyzing their behaviour and their structure. The extensive use of sensors and actuators comes from the need of the electronic control panels to know in real time the actual values of the physical parameters to be controlled or which influence the behaviour of the car.
In particular, the following components are analyzed:
Position sensors
Oxygen sensors
Temperature sensors
Pressure sensors
Air flow rate sensors
Electro pumps and geared motors
Servomotors
Electro valve
Knock sensors
Electro injectors
Coils
Level Sensors
Inertial sensors.
