Control and Feedback Systems



El Eslèk provides advanced educational solutions for learning control systems and automation techniques, designed for technical schools, universities, and professional training centers. Our modular laboratories enable students and professionals to understand, implement, and optimize control and feedback systems in practical, hands-on environments.



The training covers a wide range of topics, including:

  • Manual and automatic regulation of process variables (level, flow, pressure, temperature)
  • Open-loop and closed-loop control systems
  • PID controllers and advanced control strategies
  • Integration of sensors, actuators, and programmable logic controllers (PLCs)
  • Industrial applications and simulations of real-world automated processes



Developed with the support of experienced engineers and educators, our solutions provide precision, safety, and effective pedagogy, allowing learners to progress from basic concepts to complex control projects.



With a modular and flexible design, combined with interactive software tools, El Eslèk laboratories bridge theory and practice, helping students master modern control systems and feedback regulation in an industrial context.

The TE-101 is a comprehensive training system designed for studying and comparing different temperature measurement methods used in industrial and scientific environments.

It enables analysis of both mechanical and electronic measurement techniques, including steady-state and transient thermal behavior.

🔍 General Description

Various physical principles are used to measure temperature. The TE-101 allows users to observe and compare these methods under real operating conditions using both analog and electronic instruments.

Temperature sensors are mounted on a height-adjustable platform, allowing immersion in a heated water tank up to 80°C. A fan ensures nearly constant ambient conditions, while a second tank with an electronically controlled heater provides precise temperature control.

Measured values can be displayed in analog or digital form and recorded continuously using a 3-channel line recorder, making it possible to analyze response times and temperature variations.
