The CW-401 is a current clamp meter for amperages up to ±30 A. The device consists of a base unit and a separate sensor head, interconnected through a flexible hose. The housing has very small dimensions and is still very robust, which makes the CW-401 ideal for measurements in rugged environments and hard-to-reach places.
Even at high ambient temperatures up to +120 °C, the CW-401 has outstanding accuracy due to an intelligent compensation algorithm and its digital signal processing with an microprocessor.
Current measurements are transmitted as digital values over a CAN bus. Through this bus system typically used in automotive applications, measurements can be sent over long lines without any degradation due to EMI or noise.
In combinationen with the CW-140, the CW-401 can be used as mobile current measurement device. Measurement values and other informations can be displayed on the touchdisplay of the CW-140.
