Load Cell Testers & Simulators

Check a load cell by measuring its bridge resistance, zero balance output, and response to applied load using a calibrated instrument or bridge simulator. The i100 Strain Gage Bridge Simulator can inject precise mV/V signals (0–5 mV/V in 8 steps) to verify that the connected signal conditioner reads correctly, helping isolate faults in the load cell or instrumentation chain.

A strain gage bridge simulator replicates the electrical output of a strain gage bridge circuit without requiring an actual physical load. It is used to calibrate signal conditioners, validate data loggers, troubleshoot instrumentation systems, and perform quality control checks on measurement equipment in both laboratory and field service environments.

Yes. The i100 Strain Gage Bridge Simulator is compatible with both AC carrier and DC strain gage signal conditioner electronics. Its passive 350-ohm equivalent bridge design requires no external power supply, making it versatile for a wide range of existing instrumentation setups.

The i100 provides 8 switch-selectable output steps from 0 to 5 mV/V and a continuously variable adjustment range from 0 to 2 mV/V via a Vernier knob. It also features a true reverse polarity switch, enabling comprehensive testing of signal conditioner response across positive and negative signal directions.

Yes. The i100 is specifically designed for field service use. Its pocket-sized form factor (2¾ x 1⅞ x 6¾ inches), rugged anodized aluminum case, and passive design — requiring no external power — make it ideal for on-site troubleshooting, maintenance, and calibration of strain gage instrumentation without specialized lab infrastructure.

Yes. SensorData Technologies offers free in-house calibration when the i100 Bridge Simulator is purchased as part of a system. Their experienced engineering and technical support team is available to assist with setup, troubleshooting, and ensuring your measurement system performs to specification from day one.
