GXA3810 — 10‑Channel 32‑Bit DAQ Card for Sensor Calibration & Testing

Calibration Readback · Sensor / Joint Bench Test · 10‑Channel · 32‑Bit

The GXA3810 is a multi-channel 32-bit data acquisition card built for precision measurement in automatic sensor calibration systems and test benches. In a calibration setup it synchronously reads back the bridge output of the sensor under test while a GXR programmable resistor steps through simulated strain points — closing the loop so calibration coefficients are computed automatically for force/torque sensors used in robots and robot dogs. It also serves static performance testing of force sensors, joint-module and reducer bench testing, and modal analysis. Featuring 10 synchronous single-ended channels (5 differential), 20–400Hz band, ±5V range, 1MΩ input impedance and SE/differential/AC/DC coupling, with full Windows/Linux SDK. The same hardware is field-proven in bridge & tunnel vibration monitoring (SHM).

Frequently Asked Questions

How is the GXA3810 used in robot sensor calibration and testing?
In automatic calibration systems, the GXA3810 synchronously reads back the sensor bridge output while a GXR programmable resistor steps through simulated strain points, closing the loop so calibration coefficients are computed automatically. It also serves static performance testing of force/torque sensors, joint-module bench testing, reducer vibration testing and modal analysis.
Is the GXA3810 suitable for bridge vibration monitoring?
Yes. With 10-channel synchronous acquisition, 32-bit resolution and a 20–400Hz band optimized for low-frequency vibration, it is well suited to bridge and tunnel structural health monitoring (SHM).
What is the minimum order quantity (MOQ) for the GXA3810?
No strict MOQ for standard GXA3810 units — sample orders welcome. Tiered wholesale pricing is available for distributors and bulk orders.
Does TOPECH support OEM/ODM customization of the GXA3810?
Yes. Channel‑count adjustment, custom firmware, branded labeling and interface customization are available for OEM and ODM projects.
Can I get a GXA3810 sample before placing a bulk order?
Yes, evaluation samples ship within 3–5 business days with SDK access 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 GXA3810 include?
12‑month warranty plus lifetime technical support including SDK documentation, remote assistance and firmware updates.
