The HOBO Motor On/Off data logger records motor on and off conditions by detecting the AC magnetic fields given off by a rotating motor using its internal sensor. A second external input can be used to detect a variety of external contact closure type inputs. Using HOBOware®, you can easily configure the logger for equipment monitoring in a wide variety of applications. This compact data logger has a built-in LCD screen for checking status, battery usage, and memory consumption. You can also use the LCD screen to quickly calibrate the logger’s motor sensor near the motor to be monitored or you can set calibration to preset sensitivity levels with HOBOware. There are two models of the HOBO Motor On/Off data logger: the UX90-004 has a memory capacity of 128 KB while the UX90-004M has 512 KB.
