microUniDAQ.IEPE – mobile measuring device and data logger for IEPE sensors
The microUniDAQ.IEPE device is a compact, easy-to-use and cost-efficient USB data acquisition device, which has been specially developed for mobile use. It supports IEPE sensors as well as sensors with voltage output.
High Precision: Measurements are taken in 24-bit quality with a data acquisition rate of up to 128 kS/s.
Quick and easy USB connection: The device is USB bus-powered and does not require an additional power supply.
Overvoltage Protection and Galvanic Isolation: The analog inputs have overvoltage protection up to 40 volts. In addition, these inputs are galvanically isolated from the USB interface and digital I/Os to ensure interference-free, low-noise operation for reliable data acquisition.
Synchronization Capabilities: Connect up to four microUniDAQ devices and seamlessly synchronize them in phase, unlocking expanded possibilities for your data acquisition setup.
Stand-Alone Data Logging: Experience the flexibility of stand-alone operation. The microUniDAQ can operate as a data logger without a PC, recording data from up to four analog channels, tachometer, and rotary encoder interfaces in real-time over extended periods. Power is conveniently supplied via a USB power supply unit or power bank.
Compatibility and Integration: Combine the power of microUniDAQ with DASYLab measurement technology software to execute various measurement tasks efficiently through a user-friendly graphical interface. Additionally, an API allows for direct device access from Python or C programs, providing flexibility and compatibility in both Windows and Linux environments.
Take your data acquisition to the next level with microUniDAQ. A tool that combines precision with versatility. Whether you need to conduct complex measurements or create a seamless data logging experience, microUniDAQ is your reliable partner in the field of high-precision data acquisition.
