4. Functionality
The MDDMS3810 functions as a signal conditioning interface between a strain gauge or bridge sensor and a measurement or control system. Bridge sensors, such as load cells or pressure transducers, produce very small differential voltage signals proportional to the measured physical quantity (typically a few millivolts per volt of excitation).
The module supplies a stable excitation voltage to the sensor’s bridge circuit and measures the resulting differential signal. This low‑level signal is then amplified by a fixed gain of 500×, converting it into a standardized ±5 V output. The output can be directly connected to analog inputs of PLCs, controllers, or data acquisition systems.
Typical Use Cases and Applications:
- Industrial weighing systems using load cells.
- Force, torque, or pressure measurement setups.
- Material testing machines and calibration benches.
