Sensor Bridge Solutions

A bridge sensor balances four resistive elements in a circuit. When mechanical stress is applied, resistance in one or more arms changes, creating a measurable voltage imbalance. This output signal — expressed in mV/V — is then processed by a signal conditioner or data logger to yield an accurate physical measurement.

The Holoscan Sensor Bridge is an NVIDIA platform that enables high-speed streaming of medical sensor data for AI-powered applications. It is distinct from traditional strain gage bridge simulators. For industrial strain gage bridge simulation and calibration, SensorData Technologies' i100 offers a fully passive, precision alternative purpose-built for instrumentation environments.

The i100 Strain Gage Bridge Simulator achieves ±0.03% accuracy with a temperature coefficient of 6 ppm/F, making it suitable for precise calibration and verification of strain gage instruments, signal conditioners, and data loggers in both lab and field environments.

No. The i100 is a completely passive device, meaning it requires no external power. This makes it highly convenient for field service and portable calibration tasks, eliminating the need for batteries or power supplies while maintaining high measurement accuracy.

The i100 is compatible with both AC carrier and DC strain gage signal conditioner electronics. It simulates a 350-ohm equivalent bridge and offers 8 switch-selectable output steps from 0 to 5 mV/V, plus a continuously variable adjustment from 0 to 2 mV/V via a Vernier knob.

The i100 is used for developing and troubleshooting strain gage signal conditioners, calibrating strain gage instruments and signal processors, testing and validating data loggers, quality control of measurement systems, and field service and maintenance applications across industrial and laboratory settings.
