1.1. GENERAL
MiniFlex
®
sensors take the form of a flexible coil connected by a shielded lead to a housing containing
the signal processing electronics, powered by batteries.
The flexibility of the sensors facilitates the clamping of the conductor to be measured, whatever its nature
(cable, bar, strand, etc.) and its accessibility. The design of the coil opening and closing device, by snap
locking, allows handling while wearing protective gloves.
The electronic unit can be connected to the mV
ac
or V
ac
input of a measuring instrument having an input
impedance of ≥ 1 M
W
.
1.2. SINGLE-PHASE MINIFLEX
®
MiniFlex
®
series MA110 single‑phase sensors constitute a line of three models, 17, 25, and 35 cm long,
that convert alternating currents ranging from 3 to 3000 A into proportional AC voltages.
