Product Description

Hay Bridge

This bridge is an AC bridge used to measure the Inductance. This bridge self inductance is measurement the resistance in series with the standard capacitor. This bridge gives a simple expression for Q-Factor. This bridge given very simple expression for unknown inductance for high coil and suitable for coil. (If we examine for Q-Factor : Q = 1/ wCR4). We find that the resistance R4 appears in the denominator. Hence for high coil its value should be small. Thus this bridge only low value resistor. This bridge requires a parallel resistor.

Standard Accessories:

AC Source :The Bridge consist of sine wave signal of 1KHZ. The Amplitude of AC switch indicating lamp is provided on the bakelite board. Two sockets are provided for the output of AC signals.

Detector :For detecting small AC signals in the output, Null Detector is in-built with digital display.

Precision Measurement Capabilities

This Hay Bridge supports both inductance and capacitance measurements over wide ranges, ensuring high accuracy (0.5% of reading) with a sensitivity of 10 V. The unit is designed for exacting applications where dependable, precise results are essential, providing reliable data for educational and laboratory research.

User-Friendly and Durable Design

Built into a high-impact ABS enclosure, this portable benchtop device features ergonomic controls and a matte, anti-static finish. It is easy to handle, transport, and set up, making it suitable for laboratory benches and classroom demonstrations alike.

Safety, Compliance, and Easy Calibration

The device includes overload and short-circuit protection and is factory calibrated for immediate use. Users can recalibrate if needed. Complying with IS/IEC 61010-1 standards, it ensures operator safety and consistent performance throughout its operational range.
