HP-WDY is a high-speed wireless DAQ built for dynamic strain testing and multi-physics measurement in the field. With synchronous parallel acquisition up to 128 kHz per channel, WiFi / optional 4G transmission, and 64 GB local TF-card backup, it’s designed for reliable outdoor and vehicle test programs where fast setup and data continuity matter.
| Mixed-signal, multi-parameter acquisition | Measure strain plus supporting signals (voltage/current/temperature/vibration/speed) in one test plan. |
|---|---|
| True synchronous high-speed sampling | Channels sample, display, and store in parallel—up to 128 kHz per channel. |
| Wireless deployment, faster setup | WiFi / optional 4G helps eliminate long cable runs and supports remote data access. |
| Built-in data backup | Local TF-card storage reduces the risk of missing critical transient events. |
| Field-ready and portable | Battery-powered, modular, and easy to scale for distributed measurement points. |
Model: HP-WDY (128 kHz)
System type: Wireless dynamic strain testing & signal analysis (distributed DAQ)
Mixed input: Strain, voltage, current, force, torque, displacement, temperature, acceleration, speed, etc.
Wireless networking: WiFi self-network (short-range); optional 4G self-network (wide-area)

HP-WDY combines stable per-channel amplification/conditioning with a high-performance 24-bit ADC to deliver synchronized capture across all channels. Its wireless architecture reduces site cabling, while onboard storage supports continuous logging and post-test data retrieval—even when network conditions are imperfect.

Q1: What is HP-WDY best used for?
Dynamic strain testing and high-speed multi-channel measurement where synchronized acquisition and fast deployment are needed.
Q2: Can it measure more than strain?
Yes. It supports mixed inputs such as voltage, current, temperature, acceleration, and speed (depending on sensor type and configuration).
Q3: How is data protected if wireless transmission is unstable?
Data can be stored locally on the built-in 64 GB TF card while transmitting, reducing the chance of data loss.
Q4: How far can the wireless system work?
WiFi self-network is typically <200 m. With optional 4G, distance is not limited (subject to network coverage).
Q5: Can multiple stations be synchronized?
Yes. It supports multi-terminal networking with GPS time synchronization for aligned datasets across distributed points.
