ABSTRACT:
An apparatus for testing different electrical sensors used in machinery includes first, second and third insulated conductors, a grounded connection, a power supply, a low signal detector, a high signal detector, a varying signal detector, and an indicator. The first and second conductors are connectible to sensor under test to respectively conduct ground and supply voltage signals to the sensor. The third conductor is connectible to the sensor under test to conduct an input voltage signal from the sensor to the low, high and varying signal detectors. The low signal detector compares the input voltage signal with a low voltage reference signal. The high signal detector compares the input voltage signal with a high voltage reference signal. The varying signal detector compares the input voltage signal with a positive voltage reference signal. The low, high and varying signal detectors produce output signals of either first or second states which are received by the indicator. In response to any one of the output signals being of the first state, the indicator assumes a first condition indicating that the operation of the sensor under test is satisfactory. In response to all output signals being of the second state, the indicator assumes a second condition indicating that the operation of the sensor under test is unsatisfactory.
