GREYSTONE, represented in Australia by Sentec P/L , has introduced a new ac current sensor, the SC575. The main feature of the sensor is the split core design that allows easy installation in existing control applications.
The current sensor can monitor ‘True RMS’ ac current up to 200A and provide a loop powered 4-20mA output for PLC or DCS control. It is used in many applications, for example, in motors, pumps, fans and resistor load banks. The stated accuracy of the sensor is better than 1% and operates on a wide range of frequencies, such as 40-400Hz.
