The ETB-224 Application of Thermistors model is a compact, educational trainer kit designed to demonstrate the thermal sensitivity and electrical behavior of thermistors. It allows students to explore how thermistors (NTC/PTC types) respond to temperature changes, and how they are applied in real-world temperature sensing and control systems.

This trainer includes an inbuilt power supply, digital/analog meters, and variable temperature sources or heating elements for hands-on experimentation. The unit helps learners study resistance-temperature characteristics and understand applications like over-temperature protection, temperature compensation, and sensing.

Key Features:

• Demonstrates working of NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient) thermistors

• Built-in power supply with protective components

• Temperature variation through external or onboard heat sources

• Resistance vs. Temperature characteristic plotting

• Easy-to-use interface for students and lab instructors

• Useful in thermal management and sensor application training

Educational Objectives:

• Understand thermistor characteristics and response

• Study the behavior of thermistors in varying temperature conditions

• Analyze resistance-temperature graphs

• Learn practical applications of thermistors in sensors and circuits
