DC Linear Integrator

Linear Integrator Transducer

Description

DIN rail mounting transducers available in 55mm x 112mm or 100 x 112mm DIN  rail cases

Application

Used to conver various inputs into standard DC signals for driving panel meters and for use in control devices.

Selection Guide
M100-DI1 Single relay output
M100-DI2 Double relay output
Typical Applications
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.
