1.Product introductioniSOLUTIONS MONITOR has two basic versions:

• Wired version includes one or several wiredsensor(s) and a data collection sensor box. Thesensor box can either be installed inside the controlcabinet, or on a bracket beside the pump. The datacollected by the wired sensor installed on the pumpis transmitted into the sensor box via the sensorcable. Besides the data from the vibration sensor, thesensor box also supports other sensor types withstandard current and voltage signal output.

• Wireless version includes wireless sensor(s) withintegrated temperature and vibration monitoring.
