ATR-120MV Thin Coil Series by Aim Dynamics

Description

ATR-120MV is Aim Dynamics’ Thin Rogowski coil series.

• It outputs 120 mV per kA at 60 Hz, and 100 mV per kA at 50 Hz, yet is significantly thinner than similar Rogowski coils out there
• The diameter of the coil is a mere 8 mm, making it much easier than other Rogowski coils to thread through crowded areas in a panel
• The coil cannot be damaged by large overloads, and can measure up to 100 kA!
• The coil is completely shielded and has temperature compensation built-in, making it more accurate than competing coils
• In addition, the coil is IP67 rated, such that it can be immersed in liquid without damaging the coil
• Each unit is calibrated and test reports are available upon request
• UL Listed ATR-120MV units are available, upon request.
