Function

Measurement, visualisation and

logging of voltage, current,

frequency, hours of operation,

power, energy, cos ϕ , etc.

Standards

EN 61010-1, BS EN 60051-1-2

Series MT

Applications

Measurement of all possible electrical values from simple measurement as

voltage, current, frequency over more complex such as power and energy,

to all-in-one measurement with the netanalysing devices. 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, power, energy etc. is an absolute must and even

an indespensable asset when it comes to preventive maintenance.

Features

AC measurement devices with analogue as well as with digital technology and

readout are available. The simple devices (one measurement only i.e. voltage,

current, frequency) are only available in single phase, while the complex

devices (more than one measurement i.e. power, energy, net analyser) are also

available in 3-phase execution. 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.

The energy meters as well as the net analysers are true RMS measuring devic-

es. Monitoring and logging all electrical values on to a PC is possible by using

the MT PRG software.
