In this final project, were made a device that can measure a torque from 3
phase induction engine with 3 Hp power. This device consists of hardware to read
sensor and software to compute and send data. The torque from the engine can be
known easily, because it is directly displayed on LCD, which is shown in decimal
format.
The test had been done on every part from this torque meter, started from
sensor linearity test, AC to DC transforming test, binary signal output test and
then ended with a complete test, with sensor unattached to the engine and sensor
attached to the engine.
From the test, it is got an expected result, that the change of the sensor is
change the displayed number on LCD. This device can read the torque of the
engine, range between 1 Nm to 10 Nm with sensitivity 0,1 Nm.
