Measurement of Self Inductance by Owen's Bridge Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12328
Indian Lab Suppliers supplies the Measurement of Self Inductance by Owen's Bridge (Product ID: 12328) as part of its electronics engineering lab equipment range. It is a self-contained board for measuring an unknown self-inductance with an Owen bridge.
Quick Answer
The board carries an Owen bridge with marked arm values, driven by a built-in 1 kHz sine-wave oscillator (0-15 Vpp). An audio amplifier and speaker serve as the null detector. Three unknown inductors are selected with a band switch, a 1 kΩ 10-turn potentiometer sets the required resistance and a second potentiometer balances the bridge. A ±15 V DC, 100 mA IC-regulated supply is built in; the unit runs from 230 V ±10%, 50 Hz mains.
