GXR0101 — Programmable Resistor 1Ω–1MΩ for Vibration Sensor Calibration

Sensor Calibration · 1Ω–1MΩ · ±1Ω Accuracy · Bridge & Tunnel SHM

The GXR0101 is a high-precision programmable resistor designed for vibration sensor calibration in bridge and tunnel structural health monitoring (SHM) systems. With a resistance range from 1Ω to 1MΩ, output accuracy of ±1Ω (1Ω–1KΩ) and ±0.01% (1KΩ–1MΩ) at 25°C, it provides reliable reference values for calibrating accelerometers and vibration sensors. Equipped with gold-plated 4mm banana connectors and magnetic latching relays for power-off retention. Pairs with GXE5010 data transfer module for remote calibration control.
