Description

The flexible current clamp meter is designed and manufactured for field test AC high current and leakage current. It has the characteristics of high precision, good linearity and anti-interference ability. It can replace conventional clamp meter and large diameter clamp meter to measure high current leakage current. Widely used in electric power, communications, meteorology, railways, oil fields, construction, measurement, scientific research and teaching units, industrial and mining enterprises and other fields. It is especially suitable for current testing in industrial environments where the signal is severely distorted, such as dense line, transformer wall-to-wall core current test, thick wire cable test, relay protection, Silicon-controlled rectifier, variable frequency speed regulation, semiconductor switch, power electronic conversion equipment, arc welding, etc.

Flexible current sensor, which is called Rogowski Current Coil, using advanced Rockwell coil

technology, it is a ring coil that is evenly wound on non-ferromagnetic materials. It has no hysteresis effect, no magnetic saturation, high linearity and strong anti-interference ability. The output signal is the current-to-time differential. By integrating the output voltage signal, the input current can be truly restored. The measured current range can be from milliampere to tens of thousands of amps. The flexible current clamp coil part 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 the place of dense lines; high accuracy, reliability, responsive bandwidth, the user can customize the length of the coil according to the needs.

The meter has alarm value setting and alarm indication function, and has functions of reading, saving historical data, etc. The instrument also has functions such as data retention and data storage. It is easy to use and is an indispensable tool for electrical safety testing.
