ESAW Ballistic Galvanometer Improved Pattern (EEC-10250)
Incorporates the following features.
• These galvanometer 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 as periodic a well as a periodic instruments.
• An arrangement is provided in the instrument to make it a periodic 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 100 cm. focal length, suitable for use with Lamp and Scale Arrangement.
• Galvanometer Resistance 100 Ohms and Time period Approximate 10-12 Seconds.
• Galvanometer Resistance 500 ohms and Time period Approximate 10-12 Seconds.
