For both, J1 and J1D a new, smaller flexible Rotor Unit is available now.

Type description: J1-RF10(T) and J1D-RF13(T)
The new dimensions of 105 x 15 x 3,7mm and the weight of only 4,5 Grams are making it even more easy to run strain gauge measurements under tight environmental conditions. Due to the Rotor Unit can be “wraped” around the shaft, extremly little space is required to install the unit.

Additionally equipped with a new extended temperature range of up to 140°C operating temperature (permanently) the electronics is an absolute all-rounder.
