d.c. linear integrator, part of the hobut range of transducers

The M100-DI1 is a linear integrator which accepts D.C. inputs and integrates the input with respect to time. An output is provided via a relay which gives a pulsed output, the frequency of which is directly proportional to the amplitude of the input signal. One of the main uses of the M100-DI1 is the measurement of Watt and Kilowatt hour. This is achieved by feeding the output of a watt transducer (M100-WA series) into the M100-DI1. The input signal is integrated against time and the resulting output pulses from the relay are proportional to the kW.h being consumed. These pulses can then be fed to an electromechanical counter, digital counter or a computer, where the kWh consumed can be stored. Another se is the measurement of Ampere hours The M100-DI2 is the same as the M100-DI1 with the additional feature of having 2 relay outputs, this allows the user to feed one set of pulses to a counter on a switchboard whilst feeding the other ser of pulses to a remote computer in a control room.
