Overview
Time and pulse counters are used for the reliable monitoring of
production and service times, which enables the exact planning
and monitoring of production sequences, maintenance cycles
and warranty times.
As well as the proven electromechanical time and pulse
counters for mounting in distribution boards, we also supply
digital time and pulse counters.
The fields of application for both counter types are very diverse,
such as the recording of operating hours of machines, systems or
building management systems, as well as pulse counting for
general volume flow counting, registration of starting frequencies,
starting cycles or production quantities in systems and machines.
■
Benefits
•
Time and pulse counters help to plan maintenance intervals
and ensure high plant availability
•
Versions without zero position and with electric or manual zero
position for all applications
•
Flexible application of the digital counters for power supplies
of 12 to 150 V DC and 24 to 240 V AC in a single device.
