Applications
Measurement of basic electrical values as voltage, current, frequency. To avoid down-time due to abnormal situations, i.e. power-supply voltage too high, absorbed power too high, etc., leading to malfunctionning and even break-down of the machinery, the measurement and monitoring of the electrical values like voltage, current, frequency, etc. is an absolute must and even an indespensable asset when it comes to preventive maintenance.


Function
Measurement, visualisation and logging of voltage, current, frequency, hours of operation.


Features
• AC measurement devices with analogue technology and readout are available.
• The devices (one measurement only i.e. voltage, current, frequency) are only available in single phase.
• High currents can be measured through the intermediate use of a current transformer (for the analogue amp-meter combined with an interchangeable scale-plate).
• All devices have very good precision and have also a very low self-consumption to limit as much as possible the measurement error.
• Using one monophase-volt or amp-meter in a 3-phase system is possible by using the appropriate selector switch.
