THE DISPLACEMENT SENSORS TRAINER
PREPARED BY:NOR ATTEYYA BT MAHDINOR ADILAH BT MOHD YUSOF
INTRODUCTIONThe Displacement Sensors Trainer is a :
• Modular training system• Suitable for learning about various types of
displacement sensors and their instrumentation circuits
• An experiment manual is provided to guide both of the students and lecturer
PROJECT OBJECTIVE
Successful completion of studying this trainer will enable learner to :
• Understand the functions of sensors and signal flow
• Analyze the type of sensors and signal flow• Construct a practical test (sensor) • Develop a new displacement trainer
PROJECT SCOPES
The trainer covers the following topic areas:1. Measurement principles
i. Sensorsii. Signal conditioning
2. Sensors (Static Response)i. Strain Gaugeii. Potentiometriciii. Capacitiveiv. LVDT ( Linear Variable Differential Transformer )v. Resolver
PROBLEMS STATEMENTS
• No specific trainer for displacement sensors.• Develop new displacement sensor trainer.• As a learning tool to electronic engineering
especially Control System .• Suitable for practical test.
LITERATURE REVIEW
1. Transducer Instrumentation Trainer • The trainer consist a various type of sensor. • It covered all the electronic sensor which is difficult for
student to understand and do the practical test.2.The Displacement Sensor Trainer• This trainer consist only displacement type of sensor
which is in the syllabus of Control Systems. • The design in user friendly so, student can easily make
an experiment by using the work book that also included.
ADVANTAGES
• Learning tool.• User friendly (well organized)• Theory applied.• Portable.
ELEMENTS
The sensors and signal conditioning element of this trainer are typical of those used through industry. These elements include :
• Displacement sensors• Signal conditioning (convert into voltage,
current, or display form).
PROJECT METHOD
INPUT DEVICES
For detection of :• Length of a physical object (strain gauge)• Linear or rotary displacements
(Potentiometric, LVDT)• Rotation or rectilinear displacement
(Capacitive)• Shaft Rotation (Resolver)
OUTPUT DEVICES
For the generation of :• rotary, linear and rectilinear actions.• Visual indication of voltage, current and
display (counter).• DC Motor• Buzzer• LED

CONCLUSION
As a conclusion, the Displacement Sensor Trainer is one of the
best learning tools for lecturer and students. This trainer offer more benefit and user friendly.
This trainer also can widely use, not only for technical college but also for higher educational such as university and lower educational such as primary and secondary school especially technical and vocational school.
Nowadays, sensors are one of the important electronic devices which has a big role in modern era. Without sensor, we can’t see robot and factory with good machine and we also will never know, ASIMO.
