In the age of plc's and fuzzy logic there are still many processes in industrial applications where sequence and state have to be monitored and/or displayed by pulse evaluation systems. The use of the ecomat 200 control monitor ranges from simple standstill monitoring of a conveyor belt over the monitoring of the maximum rotational speed in wind power stations or slip monitoring on couplings to direction monitoring of gears and transport systems.
The units are reliable and easy to handle. Independent from the plc they indicate faulty operation and plant states and help to cut down on downtime and production loss.Basis for the evaluation is the conversion of mechanical movement into digital electrical signals (pulses). This is preferably done by means of non-contact sensors or encoders.
The frequency of a pulse sequence (the time distance between two consecutive positive pulse edges) is proportional to the mechanical movement so that this movement can be measured by a suitable control monitor with regard to a set behaviour. Furthermore the pulse trains can be converted into analog signals by means of frequency-to-current converters, e.g. for triggering measuring devices.
