Sci-tech Electrical Bridges Trainer Model ETR 022 consists of the following 7 Bridges:
Wheatstone’s Bridge (for measurement of Resistance)
DeSauty’s Bridge (for measurement of Capacitance)
Maxwell’s Bridge (for measurement of Inductance)
Hay’s Bridge (for measurement of Inductance)
Schering’s Bridge (for measurement of Capacitance)
Wein’s Bridge (for measurement of Frequency)
Anderson’s Bridge (for measurement of Inductance)
Each Bridge module consists of:
Dedicated, self contained trainer module for each bridge
Demonstrates the principle and working of the particular dedicated bridge
In-built IC based DC regulated power supply with short circuit protection and indication for supply “ON” to work at 230V, 50 Hz, 1 phase AC mains.
In-built 1KHz oscillator , instrumentation amplifier, differential null detector, variable arms & multipliers (as required), digital meter for null detection (non-audio) & Resistance mea.
Set of unknown components / generator (as required depending on the bridge) & necessary patch cords.
Facility to connect CRO & Head – phone set for sensitive visual / audio detection.
Test points at various stages in the circuit to observe waveforms and voltages. Each bridge module is housed in an elegant cabinet with a well spread intelligently designed layout on the front panel.
Strongly supported by a comprehensive manual complete with theory and operating details
Detailed Instruction/Experiment Manual with necessary circuit theory / diagram, operating details, tables including voltages & waveform at different test points, graphs are provided.
