VIBCONNECT RF 11.2011

Chapter 4: System description

VIBCONNECT RF is a stationary, radio-based online condition

monitoring system designed for easy installation and operation.

The system consists of the following components:

1. VIBCONNECT RF bridge

2. VIBCONNECT RF sensor unit

3. VIBCONNECT RF sensor for vibration and temperature

4.1 VIBCONNECT RF bridge

The bridge is the central reception and transmission unit in wire-

less network (star topology) that can include up to 50 sensor units

(see also “Topology of wireless network”, page 24). It receives the

measurements from the sensor unit(s), processes them and trans-

fers them to the OMNITREND software for evaluation and archiv-

ing. The bridge is supplied by the OMNITREND software with the

measuring conﬁgurations* for each measuring point and forwards

this information via radio signal to the respective sensor units.

Detailed description of function

OMNITREND loads the measuring conﬁgurations to the bridge, which

is connected through a patch cable to the local network. The bridge

then transmits this information via radio signal to the respective sen-

sor units. This happens as soon as these sensor units signal to the

bridge that they are active. The data transfer is bidirectional, i.e. the

bridge can only communicate with one sensor unit at any one time.

For vibration measurements, the sensor unit only records the related

time signal. The further processing and analysis of the time signal
