VIBCODE is a smart sensor that ensures reliable data collection even by untrained operators. It recognizes each location and takes the programmed measurements fully automatically, thereby enhancing trending reliability and eliminating repeat measurements due to mixups.
The measurement stud is encoded with location number and measurement type. A special patented probe locks onto the stud to measure both vibration and bearing condition (shock pulse) with excellent signal transmission and repeatability.

Customized solutions
The quality of a measuring system depends not only on the main components, but is also a direct result of all the system components. That is why we place high importance on optimizing the entire measuring process when developing our systems – from the sensor and signal transmission to signal processing and visualization.
Measurement precision due to state-of-the-art technology
Tandem-Piezo design
The unique features of PRUFTECHNIK's patented Tandem-Piezo accelerometers make them suitable for virtually all types of industrial vibration applications.
The unique design practically eliminates temperature shock and base strain effects; it also handles condition evaluation of turbo machinery and gearboxes, anti-friction bearings and pump cavitation - all with the same transducer, thanks to a wide linear range and a defined shock pulse resonance characteristic at 36 kHz.
Low base strain sensitivity, transverse sensitivity and sensitivity to temperature transients
High shock resistance
Integrated resonance suppression filters avoids amplifier overloading
Factory burn-in for high long-term stability
Current Line Drive (CLD)
The long cables used in permanently installed monitoring systems must stand up to considerable electrical and mechanical interference. With traditional sensors the signals barely get through the network, being drowned out by the noise and interference.
PRUFTECHNIK uses a line drive system, which consists of a tiny electronic amplifier built into each sensor to boost the vibration signal.
Low sensitivity to mechanical and electrical interference (cable noise, electromagnetic sources, ground looping)
Very long low-cost cables possible with very little signal loss
Cable positioning during installation is not as critical
Power supply current carried along the very same coaxial cable carrying the vibration signal (power comes from a source built into the receiver instrument).
There are two types of line drive systems, providing either voltage output or current output. PRUFTECHNIK systems use the latter due to its technological superiority, offering the following advantages:
Much lower high frequency loss in very long cables even over 1,000 meters.
Much lower susceptibility to induced noise and ground-loop noise, also eliminating the need for insulated sensors in most cases.
