Ballistic Galvanometer

Ballistic Galvanometer

This Galvanometer has been designed for very low current measurement.

Resistance : 100 or 500 ohms.

Time Period : 10 to 15 Sec.

• These Ballistic Galvanometers are rigid in construction beautiful in design and easy to operate, with large periodic time.
• Large moment of Inertia of the moving part of the galvanometer.
• Deflection closely proportional to the electric charge
• Ballistic Galvanometers undergo strict laboratory check before dispatch and are suitable for direct deflection measurements which are closely proportional to the current.
• These galvanometers can be used both PERIODIC as well as APERIODIC instruments.
• An arrangement is provided to make it APERIODIC by introducing a suitable resistance in parallel with the moving coil system.
• Zero adjusting and locking devices are provided. The Phosphor-bronze suspension strip prevents shifting of zero.
• The moving coil carries a specially polished front silvering concave mirror of 100cm. focal length, suitable for use with Lamp and Scale Arrangement.
