WIRELESS SENSOR FOR MEASURING DC CURRENT WITH HALL EFFECT SENSOR
- Hall effect sensor for DC current measuring
- Measure range from 0 to 1000 A
- Programmable alarm threshold
- Programmable radio transmission time
- Fast and easy installation without any interruptions of electrical service
- Battery powered
- Internal radio antenna
TWSN-Hall is a radio device, battery powered, that performs the measure of DC current with Hall effect sensor.
A significant feature is the high resistance to mechanical shocks.
TWSN- Hall transmits measures at regular intervals to a TWSN family gateway. It is possible for the operator to program the alarm threshold in order to detect any possible overcoming of minimum or maximum levels of measured currents.
