Overview
Time and pulse counters for control cabinets, control and
mechanical engineering are used, e.g. in boilers, machine tools
or compressors. The pulse counters count the starting frequencies.
This supports planning for preventative maintenance.
In-time and regular maintenance is the best protection against
unexpected shutdowns. Time counters count the time in hours
with an accuracy of two decimal places (hundredths of an hour).
■
Benefits
•
Time and pulse counters help to plan maintenance intervals
and ensure high plant availability.
