Current Sensor
The
CR9500
Series Current Sensors provides a cost effective
method for monitoring electrical current. The sensor generates a
0-5 VDC signal proportional to the input AC current. The output
signal is average sensing, calibrated to RMS.
The sensor is used with process control and industrial instrumen-
tation equipment. Especially suited for OEM applications that
require a low cost solution for numerous monitoring locations.
The DC output can be connected directly to an analog input
connection without additional signal conditioning. Care must be
taken to ensure the burden impedance of the instrumentation is
greater than 1.0 megohm. The unit will operate with lower bur-
den impedance but at reduced accuracy.
