The Dielectric Constant Measurement by De Sauty Bridge from AGN Enterprises is an educational electrical laboratory trainer designed to study capacitance and determine the dielectric constant (relative permittivity) of a dielectric material using the De Sauty bridge principle.
The illustrated apparatus features an integrated digital null detector, clearly printed bridge circuit, capacitance adjustment controls, resistance controls, color-coded terminals, and power switch. Its compact trainer-style construction makes circuit connections and balance adjustments convenient for students.
The apparatus provides practical experience with capacitor comparison, bridge balancing, dielectric materials, capacitance, relative permittivity, and null measurement techniques.
It is suitable for physics laboratories, electrical engineering laboratories, electronics departments, colleges, universities, polytechnics, and technical institutes.
Capacitance Bridge for Measurement of Unknown Capacitance
This bridge is designed for accurate measurement of an unknown capacitance value. The complete instrument is housed in a sturdy ABS plastic enclosure and incorporates all essential components required for bridge operation.
Built-in Features
- AC Source: The bridge includes an internal 1 kHz sine-wave oscillator. An indicator lamp on the Bakelite panel shows the AC supply status, while two output sockets are provided for AC signal connections.
- Null Detector: A sensitive digital null detector is integrated into the instrument for detecting very small AC signals and achieving precise bridge balance.
- Circuit Layout: The circuit diagram is clearly displayed on the panel with a spacious layout to simplify operation and enhance understanding. Standard 4 mm sockets are provided for convenient wiring and interconnections.
Specifications
- R₂: Three-decade resistance network with ranges of 10 × 1000 Ω, 10 × 100 Ω, and 10 × 10 Ω for accurate resistance adjustment.
- R₁: Single-decade resistance dial with a range of 10 × 100 Ω.
- C₁: Unknown capacitor whose capacitance is to be measured.
- C₂: Two fixed, low-loss standard capacitors of 0.01 µF and 0.1 µF used as reference capacitors in the bridge circuit.
