GZ121–Mechanically connected tachogenerator with alternating voltage output signal : NORIS Group GmbH

High-quality tachogenerator with two galvanically isolated alternating voltage outputs
Suitable for extremely harsh operating conditions
Direct and indirect drive possible
Degree of protection: IP66
Variable mechanical connections for speed acquisition

Tachogenerators of type GZ121 are mechanically connected 2-channel speed encoders with a sinusoidal alternating voltage output signal. They are attached to the shaft via a flange or bracket. The mechanical connection is realised via a coupling. They do not require any power supply. These tachogenerators are suitable for acquiring shaft speeds. Their compact and robust design, as well as their approval by shipbuilding industry classification societies, make them ideal for marine applications.

Measuring range	150 - 2,500 rpm
Output channels	2 channels
Output signal	2 x galvanically isolated alternating voltage
Operating temperature	-20 … +80°C
