I. Product Overview
The dynamic sensor signal acquisition unit is a specialised accessory for performance testing systems for electric motors, water pumps, fans and servo modules, primarily used for the high-speed acquisition, conversion and transmission of various types of dynamic analogue signals. The device can interface with signals from a wide range of sensors, including those measuring pressure, flow rate, temperature, torque, vibration and rotational speed. Through high-speed AD sampling modules, it performs real-time data acquisition, filtering and conversion, and reliably outputs standardised data to the host control system. Offering strong compatibility, high sampling rates and excellent data consistency, the device is widely used in scenarios such as factory quality inspection, R&D performance testing and the recording of dynamic operational data, making it an essential piece of equipment for automated test benches.
II. Key Features
1. Simultaneous acquisition of multiple dynamic signals: Supports synchronous sampling of multiple analogue signals, allowing simultaneous connection of various voltage-type and current-type industrial sensors. It synchronously records multi-dimensional test data—including pressure, temperature, torque, vibration and flow—to meet the data acquisition requirements of comprehensive performance testing.
2. High-Speed AD Sampling and Data Filtering: Equipped with an industrial-grade high-speed AD conversion chip, it offers rapid sampling rates. Built-in multi-stage digital filtering algorithms effectively mitigate data jitter caused by pipeline fluctuations, equipment start-up and shutdown, and electromagnetic interference in the workshop, thereby enhancing the stability of test data.
3. Customisable Parameter Conversion: Supports customisation of sensor coefficients and range parameters, allowing for parameter calibration according to different sensor models and testing conditions, and is compatible with a wide range of sensor devices.
4. Real-time Data Upload and Logging: The device supports real-time communication with industrial PCs, PLCs and host computer testing software. Collected data can be uploaded in real time, automatically stored and continuously logged, enabling subsequent data retrieval, analysis and graph plotting.
5.Suitable for Dynamic Operating Condition Testing: Optimised for dynamic test scenarios involving variable motor speeds, variable pump flow rates and variable loads, it can capture instantaneous data changes during operating condition transitions, meeting data acquisition standards for dynamic performance testing.
III. Key Product Advantages
1. Wide versatility, compatible with multiple sensor types
The device is compatible with mainstream industrial sensor signal formats and can be used with a variety of sensors, including those for pressure, temperature, torque, rotational speed, vibration and displacement. It can be flexibly integrated with motor test benches, pump test benches and fan test systems, thereby reducing the cost of procuring supporting equipment.
2. Stable Sampling Accuracy and High Repeatability
Featuring high-precision signal acquisition circuits and an isolated, anti-interference design, the system minimises the impact of external environmental factors on signals. With minimal sampling error and excellent data repeatability, it meets the accuracy requirements for both routine quality inspections in factories and laboratory type testing.
3. High Integration, Simple Installation and Commissioning
The unit features a compact structure and clear wiring logic, supporting centralised cabling installation. With a built-in parameter calibration function, operators can quickly complete channel calibration and parameter settings, making it suitable for batch testing on production lines.
4. Industrial-grade anti-interference design
The circuitry incorporates isolation protection, surge suppression and electromagnetic shielding, enabling it to adapt to complex operating conditions such as motor start-stop cycles, variable frequency interference and pipeline vibrations in workshops. It operates stably during prolonged continuous operation with a low failure rate.
5. Strong system compatibility and convenient integration
Equipped as standard with industrial communication interfaces, it integrates seamlessly with our proprietary test software and mainstream industrial control systems available on the market. It can work in conjunction with electrical parameter analysers, flow and speed meters, and pressure and head gauges to complete a full automated test process.
IV. Applicable Scenarios
This equipment is widely used in comprehensive electronic pump test systems, motor factory acceptance test benches, servo joint module test benches and fan performance testing equipment. It is suitable for dynamic performance testing, operating condition data acquisition, performance calibration, R&D testing and factory quality inspection of various motors, water pumps, fluid equipment and automation components, and is suitable for use in production workshops, quality inspection laboratories and university research and testing platforms.
VI. Support Services
The equipment supports bespoke customisation of channel count, sampling rate and communication protocols to accommodate different customers’ test processes and system architectures. The manufacturer provides equipment calibration, installation and commissioning, operator training, long-term technical support and after-sales maintenance services to ensure the long-term stable operation of the equipment and meet enterprises’ standardised quality control requirements.
