M100 Linear Integrator Transducer

Selection Guide
M100-DI1 Single relay output
M100-DI2 Double relay output

Typical Applications
The M100-DI1 is a linear integrator which accepts a D.C. input signal and integrates the input with respect to time. An ouput 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 then can be fed to an electromechanical counter, digital counter or a computer, where they can be stored.
Another use is the measurement of Ampere hours.
The M100- DI2 is the same as 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 set of pulses to a remote computer in a control room.

M100 Thermocouple Temperature Transducer

Selection Guide
M100-TJ1 Type J thermocouple
M100-TK1 Type K thermocouple

Typical Applications
The M100-TJ1 and TK1 measure the millivolt signal from of J and K type thermocouples respectively.
Thermocouples are made from two dissimilar metals and as the temperature rises, the mV across the thermocouple increases. Thermocouple manufacturers provide tables showing temperature versus voltage characteristics of their thermocouples.
The small voltage developed corresponds to a change in temperature. The M100 TJ1 / TK1 measures this voltage change and converts it to an output signal that corresponds to the temperature being monitored. The output from the M100-TJ1/ TK1 is not linearised.
Thermocouple temperature measurement is used in a variety of applications, including monitoring of temperature of furnaces etc.
The M100 thermocouple transducer is provided with automatic cold junction temperature compensation over the range 0-50 °C.
Also provided is thermocouple break protection. Should the thermocouple leads break, the output from the transducer will go to its maximum or minimum output value, depending on which option is chosen at time of ordering.
