Product Code : SCL-EELE-13303
Indian Lab Suppliers supplies the Displacement Measurement Trainer Using LDR, Photo Transistor and Photo Diode Setup (Product ID: 13303) as part of its electronics engineering lab equipment range. It uses a lamp and three light sensors, an LDR, a phototransistor and a photodiode, to relate output to displacement.
Quick Answer
A 12 V bulb sits at one end of a fixed pipe, and three slide pipes carrying the LDR, phototransistor and photodiode move up to 10 cm inside it, so the light reaching each sensor falls as it moves away. Students plot LDR resistance against displacement at constant lamp voltage, and LDR resistance against lamp voltage at fixed displacement, then photodiode and phototransistor voltage against displacement. A potentiometer sets the lamp between 5 and 12 V from a 500 mA supply, and a dual-range (2 V / 20 V) 3½-digit meter reads lamp and sensor voltages; a multimeter is supplied for resistance. It runs on 230 V ±10%, 50 Hz. The bulb gets warm in use.
