GXR0115 — Programmable Resistor 1Ω–15MΩ for Robot Force/Torque Sensor Calibration

Strain Gauge Simulator · 1Ω–15MΩ · 2 mΩ Step · 0.01% Accuracy

The GXR0115 is an ultra-high-precision programmable resistor that works as a programmable strain-gauge simulator. It replaces Wheatstone bridge arms to generate exact, repeatable bridge outputs — enabling fully automatic production-line calibration of strain-gauge-based force and torque sensors for humanoid robots and robot dogs (6-axis force/torque, joint torque, 1-axis force). With 1Ω–15MΩ range, 2mΩ minimum step (≈2.9 µε at 350Ω, GF≈2) and 0.01% accuracy in the 100Ω–1MΩ range, it turns manual resistor-box calibration (3–5 minutes per sensor) into an automated seconds-long scan. Magnetic latching relays retain values after power loss and switch in milliseconds; command-line control via USB/ETH with GXE5010 gateway. Also used for vibration sensor calibration in bridge & tunnel SHM systems.

Frequently Asked Questions

How is the GXR0115 used to calibrate robot force/torque sensors?
Strain-gauge-based force/torque sensors all use Wheatstone bridges. The GXR0115 replaces a bridge arm and outputs precise simulated strain values for point-by-point automatic calibration. With a 350Ω gauge (GF≈2), the 2mΩ step equals about 2.9 µε resolution; simulated strain accuracy reaches 0.01% of reading. Paired with GXA3810 DAQ readback, one sensor is calibrated in seconds instead of minutes.
What is the minimum order quantity (MOQ) for the GXR0115?
No strict MOQ for standard GXR0115 units — sample orders welcome. Tiered wholesale pricing is available for distributors and bulk orders.
Does TOPECH support OEM/ODM customization of the GXR0115?
Yes. Custom resistance ranges, control interfaces, branded labeling and enclosure options are available for OEM and ODM projects.
Can I get a GXR0115 sample before placing a bulk order?
Yes, evaluation samples ship within 3–5 business days with documentation and remote technical support during testing.
What is the lead time and how do you ship worldwide?
Standard lead time is 1–3 weeks. Worldwide shipping via DHL, FedEx, UPS and air/sea freight with export packaging.
What warranty does the GXR0115 include?
12‑month warranty plus lifetime technical support including remote assistance from our Chengdu engineering team.
