HP-JYS is a 2 Hz synchronized, multi-channel data acquisition system designed for static stress/strain testing and slow-changing signals. It combines embedded Win10 operation, bridge measurement for strain gauges, and modular expansion for multi-point tests.
| Embedded Win10 + 7" touch screen | Standalone operation or PC connection via USB communication module; easy deployment. |
|---|---|
| Universal multi-sensor input | Supports multiple sensor types (strain, current, voltage, temperature, resistance, displacement, etc.) for flexible test setups. |
| High-accuracy architecture | Independent high-precision 120 Ω bridge resistor per channel, stable conditioning/amplification circuitry, and high-performance ADC for reliable static measurements. |
| 2 Hz synchronized sampling | Keeps channel data comparable for static stress/strain tests and slow-varying signals. |
| Optional battery power | Optional built-in lithium battery for field tests when AC 220V is inconvenient. |
| Portable modular design | Lightweight, modular expansion; customize measurement points and build scalable multi-channel acquisition networks. |

Q1: Is 2 Hz sampling enough for strain testing?
For static tests and slow-changing strain signals, 2 Hz synchronized sampling is commonly used to keep data stable and comparable across channels.
Q2: What bridge wiring does HP-JYS support?
It supports full bridge, half bridge, and quarter bridge, including 2-wire/3-wire quarter bridge and compensation wiring.
Q3: Can I use HP-JYS in the field without AC power?
Yes. The system supports DC 12V, and an optional built-in lithium battery is available for on-site testing.
Q4: How many channels can I build?
HP-JYS supports 10–100 channels (depending on configuration) and can be networked for multi-point measurement projects.
