- Axle Drives With our balancing machines for front and rear axle transmissions, the measured unbalance is corrected by drilling into the drive flanges of the transmissions (welding optional). We support you with our interdisciplinary expertise in the production of front and rear axle transmissions from the initial idea to the design stage through to series production.

Frequently asked questions
Answers to the most common questions about our products and services
It is a single-axis charge accelerometer using piezoelectric shear sensing. It measures machinery vibration, with an Ex configuration subject to its certificate.
The manufacturer manual identifies the external 2667 charge amplifier. In a hazardous-area installation, check sensor, cable, amplifier and safety barriers as a system.
5704-S is documented from 1 Hz to 10 kHz at ±10%. W1 includes a 2 kHz low-pass filter, so the S-version bandwidth must not be applied to it.
Its measuring range is ±2000 m/s² peak, with 10 pC/(m/s²) sensitivity at ±5% at the reference frequency. Shock and sinusoidal survivability are specified separately.
Total capacitance changes with cable length. Check it against the approved circuit data and preserve housing grounding, mounting and cable transitions specified in the installation instructions.
