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.
