The SAMOA 383100 U·TANK is a dual-tank monitoring module within the NEX-U fluid management system. It continuously reads tank levels from each connected vessel—using analog pressure or ultrasonic probes, or digital level sensors—and displays real-time inventory on two independent graphic screens. When a tank approaches empty, the module cuts air supply to the corresponding pump to prevent dry running and cavitation damage. During filling, it commands an electro-pneumatic valve to close, preventing overflow of clean oil or waste fluid.

Which probes are compatible with the U·TANK?

The module accepts both analog and digital probe types per tank. The analog input supports 4–20 mA or 0–10 V signals from pressure-based or ultrasonic level probes, which enable continuous real-time inventory tracking. Three digital inputs per tank accept low, mid, and high-level switch signals—though note that digital probes cannot provide real-time inventory data; the system defaults to a decremental balance method requiring periodic manual adjustment.

How does the module communicate with the rest of the system?

The U·TANK connects to the NEX-U network via CAN-bus for wired integration and includes built-in Wi-Fi for wireless access. This dual-communication design allows workshop operators to check tank status from any workstation, and the module also controls a global air solenoid that shuts off all pump air supply when the workshop is closed.
