Integration with Existing Process
Monitoring and Control Systems
Many industrial plants have a variety
of process sensors strategically
placed around their site so that safety,
environmental impact and efficiency
can be monitored and managed, in real
time, from one or more control rooms.
The Cirrus Environmental Noisesensor
can be connected with unparalleled
ease to such a system sending out
continuous live data.

Effective   Noise   Monitoring   Solution
Given the ever increasing need to accuray monitor and control the environmental
noise impact generated by industrial processes and sites, the Class 1 MK:427
Noisesensor affords companies an effective means of managing and controlling
noise levels.
A   number   of   MK:427   units   have   been
supplied   to   a   large   industrial   site   where
there   was   a   need   to   feed   live   noise
information   into   an   existing   system.   The
robust   design   and   simple   interface   made
the   MK:427   ideal   for   this   application   and
provides   the   operator   with   a   reliable
and   simple   way   to   monitor   and   display
live   noise   levels   along   with   the   other
data   vital   for   the   operation   of   the   site.
