The Chell microDAQ3 represents a significant advancement in pressure scanning technology, integrating high-precision digital sensors with an advanced processor for superior data accuracy and versatility. It delivers both differential and absolute pressure data, compensated in engineering units, via Ethernet, CAN, IENA, and EtherCAT, achieving sampling rates up to 400Hz per channel. An optional electrically driven valve allows for system purging and re-zeroing, featuring precise positional measurement and current monitoring for consistent performance. Despite its comprehensive functionality, it maintains a compact form factor, being the smallest digital pressure scanner available, even with the valve attached. Without the valve, the device is even smaller. Equipped with high precision transducers and dual 24-bit ADCs for pressure and temperature per port, the microDAQ3 compensates for thermal effects across a wide operational range. It incorporates technologies like an embedded web server, IEEE 1588 PTP time stamping, power-over-Ethernet, and more, showcasing its technical prowess.
