"If the federal government does not want to meet its commitments, there is no sense in returning to the dialogue," Tacho
Spy is relied upon by many dealers and buyers throughout Germany and has expanded into several other countries in Europe.
The recorder has eight to 40 channels in a laptop-size unit with embedded signal conditioning supporting sensors for noise and vibration measurements, as well as tacho
, strain, temperature and displacement data.
On a train, this measurement is made with an axle-mounted toothed geared wheel, called a phonic wheel, coupled to a magnetic sensor that generates a tacho
signal consisting of pulses at a frequency proportional to the rotational speed.
It has a six-speed, close-ratio gear box, Kayaba suspension front and rear, Nissin two-piston front brakes and single-piston rear, and an instrument display whose functions include LCD speedo and tacho
dial, trip computer, odo and clock, lap timer with 99-lap memory and gear position indicator.
In low cost installations, where the use of a tacho
generator would not be cost effective, speed regulation is achieved using armature voltage feedback.
