Maxwell Inductance Bridge
Product Code : JA-SI-8073
The Maxwell Inductance Bridge (SKU JA-SI-8073) measures an unknown inductance by comparing it with a standard variable inductance, the L2 decade of x10 mH, together with a resistance decade R2 of x1 ohm. The ratio arms R3 and R4 are two-decade dials of x10 and x100 ohm. A 1 kHz sine source with two output sockets and an amplitude indicating lamp and a digital null detector are built into the board, and four unknown inductances are supplied.
