MODEL I-210B
CURRENT SENSOR
DESCRIPTION
The PRODYN Model I-210B Sensor is a clamp-on, radiation-hardened current transformer. The sensor is designed to measure the current on cable bundles. The differential output voltage is an accurate representation of the total current flowing through the central aperture of the sensor (subject to bandwidth limitations of the sensor). The relationship between the sensed current and output voltage is:
differential Vout = RT x Isensed; RT = transfer impedance
The sensor is split to allow clamping the device onto a cable, cable bundle, or structural member that fits the central aperture. The presence of the sensor adds a series impedance to the sensed current carrier. This is referred to as the Insertion Impedance.
