Hall effect sensor for direct current measurements
DB2-CT1000
 |
Key features
|
The DB2-CT1000 is a battery powered ZigBee device that can perform direct current measurements through the Hall effect sensor and send them at regular intervals to one of a Gateway of the Digitron products family.
This measure is based on the magnetic effect caused by the electric current fl ow along the conductor. To properly use this sensor, it should be placed on the conductor at a distance that is proportional to the amount of current that is to be measured. The range is between 0 and 1000 Acc.
This device may be confi gured to manage alarm thresholds for exceeding maximum or minimum current levels. It is also possible to adjust the sampling and data transmission rate to improve battery life.
