Low Range AC Current Sensors
Connect directly to any XR450 or XR5-SE Data Logger. Or connect to a recorder or data acquisition system's 0-5vdc input. No external power required.
- Self powered
- Split core design
- Rugged molded plastic housing
- Connect up to four (4) AC Current Sensors to the XR450 Data Logger
- Connect up to eight (8) AC Current Sensors to the XR5-SE Data Logger
Split core construction simplifies installation on existing conductor. Nylon thumb screws, no exposed metal parts; Monitor motors, pumps, or any AC load.
