Wave Staff XB
The OSSI010-025 Wave Staff XB is a water level sensor that combines a rugged, IP67 resistant to water submersion package, Xbee RF Module, low power microprocessor and Anti-aliasing sensing circuit. Months of operation with two Industry standard C size alkaline batteries. Sensor Staffs from 0.5 meters long to 20 meters long. The self-grounding Coaxial Rod and Cable Staffs eliminate the need for a separate water ground wire. Laptops and PCs can easily receive the Wave Staff XBÂ’s data with any one of several optional wireless Adaptors. Time stamped data can be used to synchronize up to 8 Wave Staff XBs. A new, easy to use, PC Interface Program is available to down load from our web site to configure, display, analyze and store the sensor data.
