Multi Channel Digital Strain Indicator
FOR STRAIN GAUGE BRIDGE
- Input configurations: 1.2 & 4 arm strain gauge networks
- Resistance of Strain gauge: Nominal 120 Ohms. 300 Ohms and 600 Ohms in 1.2 & 4 arm active networks and other values in 2 & 4 arm active networks
- Bridge balance: Ten-Turn Potentiometer permits to get bridge balanced against difference in gauge resistances upto 1.5%
- Bridge selection: Manual by digital selection switch. Auto by scanning system with the time interval between channels adjustable from 5 to 180 sees
- Calibration and: A Calibration switch and circuit is provided either to compensation facility calibrate or to compensate a preload. This circuit pro-duces dignal equivalent to +/-10000 microstrains. This facilitates the user to study very small dynamic strain over and above large static strain level
- Bridge excitation: Approx 5 Volts DC Stabilised
- Gauge factor adjustment: 1.5 to 4.5 continuous
- Indication: Digital Panel Meter
- Recorder Output: 1000 Milli Volts/10000 microstrains. across 1000 Ohms
- Power supply: 230 Volts. 50 Hz. AC Mains
