Holthausen Elektronik develops and produces customized solutions for the vibration monitoring.
Uncontrolled vibrations can cause cost-intensive service- or repair work.
This perhaps can lead to machine downtime or even to loss of prouction.
Also life threatening situations may arise by excessive vibrations at technical installations.
With our security-related products, you can detect problems early and resolve them for low-cost.
In addition to the vibration monitoring we offer:
- level monitoring
- SMD-assembly
- cable assembly
- contract manufacturing and the devices mounted on.
