Products Description
DW202
DW202 series flexible current clamp meter is designed and manufactured for field test of ac high current and leakage current.With high precision, good linearity and anti-interference ability, it can replace the traditional ordinary clamp meter and large-caliber clamp meter to measure large current leakage current, which is widely used in electric power, communication, meteorology, railway, oil field, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields.It is especially suitable for current testing in places with dense wiring, transformer wall-to-wall grounded iron core current testing, coarse conductor cable testing, relay protection, SCR rectifier, frequency conversion speed regulation, semiconductor switch, power electronic conversion equipment, arc welding and other industrial environments with severe signal distortion. Flexible current sensor, namely Rogowski Coil(Roche Coil), adopts advanced Roche Coil(also known as Roche Coil) technology, which is a circular Coil uniformly wound on non-ferromagnetic materials, with no hysteresis effect, no magnetic saturation phenomenon, high linearity and strong anti-interference ability.The output signal is the derivative of the current with respect to time. By integrating the output voltage signal, the input current can be truly restored, and its measurement current can range from milliamps to tens of thousands of amps.Flexible current clamp coil has no exposed metal conductor, non-contact measurement, safe and fast;Its small size, light weight, beautiful appearance, soft and flexible, suitable for narrow environment and densely arranged places;High measurement accuracy, high reliability, wide response frequency band, the user can customize the length of the coil according to the demand. The instrument also has the functions of alternating direct current voltage test, alarm above the set value, data retention, data storage and so on. It is easy to use and an essential tool for electrical safety detection.
