PCE Instruments PCE-CM 40 Flexible multimeter up to 3000A, 170mm diameter Rogowski coil, works Inrush
(Incl. Tax: €233.01)
The PCE-CM 40 is a flexible multimeter designed to measure current up to 3000A using a Rogowski coil with a diameter of 170mm. It offers a feature for measuring inrush currents, making it suitable for applications that require the monitoring of transient current surges. This device combines versatility and precision, making it ideal for electrical professionals and maintenance technicians.
The PCE-CM 40 flexible multimeter offers an innovative solution for measuring AC currents up to 3000 A, ideal for analyzing machinery and electrical systems. Its core technology relies on a 170 mm diameter Rogowski coil - a special transducer that, unlike traditional clamp meters with ferromagnetic cores, operates through non-contact electromagnetic induction. When wrapped around a conductor, the coil detects changes in the magnetic field, generating a voltage proportional to the current's rate of change (di/dt). This physical principle enables precise, safe measurements of extremely high currents without the saturation risks of conventional methods.
