Measurement of Speed Using Photoelectric Transducer Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-13305
Indian Lab Suppliers supplies the Measurement of Speed Using Photoelectric Transducer (Product ID: 13305) as part of its electronics engineering lab equipment range. It measures motor speed in rpm by counting light pulses through a slotted disc with an infrared opto-coupler.
Quick Answer
A disc with 12 evenly spaced holes turns on a 12 V DC motor shaft between an infrared LED and a phototransistor in a slotted opto-coupler. Each hole lets light through, so the phototransistor switches 12 times per revolution; an 8051 microcontroller counts the pulses, divides by 12 and shows the speed in rpm on a 4-digit seven-segment display. The board has ±12 V and 5 V, 100 mA IC-regulated supplies and runs on 230 V AC ±10%, 50 Hz. Keep fingers clear of the spinning disc.
