HP-YD40 is a modular, multi-channel remote monitoring and data acquisition (DAQ) system designed for long-term field measurement and online supervision. It supports mixed sensor inputs per channel (strain, force, voltage, current, resistance, IEPE accelerometers, magnetic speed/displacement sensors, etc.) with synchronous sampling, display, and storage—ideal for industrial condition monitoring and structural health monitoring (SHM).
| Universal Mixed Inputs | Each channel can connect different sensors (strain/force/voltage/current/resistance/IEPE acceleration/magnetic speed & displacement) without additional auxiliary equipment. |
|---|---|
| Synchronous Multi-Point Acquisition | All channels sample, display, and store in sync, supporting high-speed synchronized logging (spec listed up to 200 Hz). |
| Independent Channel Architecture | Per-channel stable amplification/conditioning + high-performance ADC improves accuracy, consistency, and anti-interference for long-term monitoring. |
| Auto Balance / Zeroing | Automatic channel balancing to clear zero, plus manual offset/zero settings to match test requirements. |
| High Accuracy Measurement | Built-in precision 120 Ω bridge resistor per channel and stable conditioning deliver measurement accuracy to ±0.2% (system spec). |
Product Type: Lightweight remote online monitoring + multi-sensor DAQ
Channel Capacity: Modular 8–40 channels (configurable)
Use Cases: Remote field tests, unattended monitoring, multi-point synchronized measurement
Connectivity: 100 Mbps Ethernet + 4G, supports offline operation

HP-YD40 is built around independent per-channel signal conditioning and high-performance A/D conversion for stable, interference-resistant measurement. Every channel can be configured for different sensor types without extra external conditioning modules, enabling true mixed-input acquisition. The system supports fully synchronized multi-point sampling, and provides automatic balancing/zeroing per channel, with manual zero setting for experiments that require offset points.

Q1: How many channels can I configure on HP-YD40?
A: It supports 8 to 40 channels with a modular design, so you can scale based on measurement points.
Q2: Can I connect different sensor types on different channels at the same time?
A: Yes. HP-YD40 supports mixed inputs per channel, so strain + IEPE acceleration + voltage/current, etc., can run simultaneously.
Q3: What is the sampling rate?
A: The system supports 1–1000 Hz software-configurable sampling. For fully synchronized high-speed logging, the spec also lists up to 200 Hz.
Q4: Does it support strain gauge bridge wiring?
A: Yes—full bridge, half bridge, quarter bridge (2-wire), quarter bridge (3-wire).
Q5: How accurate is the measurement?
A: System measurement accuracy is specified at ±0.2%, with per-channel precision components (including a built-in 120 Ω bridge resistor).
Q6: Can it work in remote outdoor sites without stable AC power?
A: Yes. It supports large-capacity battery and optional solar / wind charging, plus smart power management for long unattended operation.
Q7: What communication options are available?
A: 100 Mbps Ethernet and 4G are supported, and the system can also support offline operation.
Q8: What triggering/recording modes are supported?
A: Continuous, timed/scheduled, and external trigger acquisition are supported, with configurable recording duration.
