HP-YD32 is a lightweight, remote online monitoring and data acquisition (DAQ) system built for long-term, multi-point measurement. With 32 synchronized channels and built-in signal conditioning, it supports mixed sensor inputs—strain, voltage, current, resistance, IEPE accelerometers, magnetic sensors, and more—without extra external modules.
| True Mixed Inputs per Channel | Connect force/strain/voltage/current/resistance/IEPE/magnetic sensors directly—no additional auxiliary equipment required |
|---|---|
| 200 Hz Synchronous Acquisition | All channels sample, display, and store data simultaneously (max 200 Hz) |
| Independent Channel Architecture | Dedicated conditioning + high-performance ADC per channel for accuracy and consistency |
| Strong Anti-Interference | Improves signal integrity in noisy industrial or field environments |
| Auto Balance (Zeroing) | One-click per-channel balance for clean baselines; supports custom unbalance point settings |
| High Accuracy Measurement | Built-in precision bridge components and stable conditioning for reliable strain/bridge measurements |
| Long-Term Stability | Designed for stable readings over extended monitoring periods |
Model: HP-YD32
Product Type: Lightweight remote online monitoring / multi-channel data acquisition system
Core Capability: 32 channels, all-channel synchronous sampling, display, and data storage
Mixed-Input Design: Each channel can be configured independently with built-in conditioning circuits for multiple sensor types
Measurement Performance: High anti-interference design and long-term stability; measurement accuracy up to ±0.2%
HP-YD32 is designed for engineering tests and continuous monitoring where multiple sensors must be collected at the same time. Each channel includes an independent, high-stability signal amplification/conditioning stage and a high-performance A/D converter to maintain consistency and reliability over long deployments. Automatic balance (zero) helps streamline setup, while manual zero configuration supports special test requirements.

Q1: Can different channels measure different sensor types at the same time?
Yes. HP-YD32 supports mixed inputs, and each channel can be configured independently (strain/voltage/current/IEPE, etc.).
Q2: What does “synchronous acquisition” mean in real tests?
All channels sample at the same time, which is critical for comparing multi-point data (e.g., load/strain/displacement correlations).
Q3: Is 200 Hz fixed?
No. The sampling rate is software adjustable up to 200 Hz.
Q4: Do I need an external IEPE power module for accelerometers?
No. The system includes a built-in 4 mA constant current source and conditioning circuit for IEPE sensors.
Q5: How do I zero (balance) strain channels before a test?
Each channel supports automatic balance (zeroing). Manual zero/unbalance point settings are also available for special test requirements.
Q6: What voltage/current signal ranges are supported?
Voltage supports single-ended/differential with ranges from ±50 mV up to ±10 V. Current supports 0–20 mA, 0–40 mA, and 0–80 mA.
Q7: What bridge configurations are supported for strain gauges?
Full bridge, half bridge, quarter bridge (2-wire), and quarter bridge (3-wire) are supported, with multiple selectable strain ranges.
