Electro-Mechanical Counter & Longscale Indicator
This class 1.0 instrument uses microprocessor controlled
circuitry for optimum performance and accuracy. The unit
takes the incoming voltage and current signals and converts
them into numbers representing the instantaneous values.
These are then multiplied together to give the instantaneous
power.
This sampling is repeated many times during each cycle of
the wave form, which allows accurate measurements of
distorted waveforms. These values are accumulated until
enough energy has been measured to increment the counter by
one digit. There is also an LED indicator which is pulsed
when power is flowing.
The new class 1.0 series of kilowatt hour meters is a major
upgrade on Cromptons world beating innovative range of self
contained kW.h meters designed as either a kilowatt hour
counter or as a combined kW.h counter with an analogue
display of instantaneous power in kilowatts in a single
integrated instrument. This provides savings in both cost
and space when replacing conventional instruments.
These instruments are ideal for class 1.0 or secondary
metering in switchgear, plant instrumentation and process
control applications offering considerable advantages over
the traditional disc type kilowatt hour meter together with
the ability to indicate instantaneous Watts and to provide a
pulsed output of kilowatt hours for data loggers or
computers.
This range of products can be scaled in Watts, Kilowatts and
Megawatts; and a range of kVAr.h meters is also available.
All models are switchboard panel mountable.
