Introduction
Figure 2.4 Monitoring vibration and temperature in chillers.
Vibration measurements encompass the frequency (velocity), amplitude
(strength), and acceleration (intensity) of the vibration.

Vibration measurements provide insight into potential mechanical issues. This
device is well suited for identifying imbalances, eccentricity, loose parts, and
misalignment. In addition, remote sensors include a surface temperature ther-
mometer that identifies potential over-heating issues. Excessive vibration and
over-temperature conditions can shorten the life of machinery and compo-
nents, pose safety hazards, and create excessive noise.
Acceleration is measured in 'g' units (gravitational constant). Velocity is repre-
sented in mm/s (millimetres per second) and in/s (inches per second) units
and is derived from internal calculations. Temperature measurements are pre-
sented in ℃ and ℉ units.
The remote sensors attach directly to machinery, using the supplied double-
sided tape, and transmit data to the remote monitoring gateway via Bluetooth
which in turn communicates to a mobile device and Windows PC. Adhesive
alternatives are available commercially that could be more reliable on some
machinery (see the Specifications section for details). The system consists of
the following components:
