FIELD: measurement technology; diagnosing systems for submersible motor-driven pumps.
SUBSTANCE: proposed transducer has protective gear whose input functions as transducer input, semiconductor diode, thermistor, pressure measuring transducer, electromagnetic relay, and threshold element. Protective gear has fuse, varistor, and LC filter incorporating choke and capacitor. Electromagnetic relay and choke coils function as temperature sensors. As an alternative, proposed transducer may have separate temperature sensor. Transducer can function both when submersible pump is ON and OFF.
EFFECT: enhanced reliability and enlarged functional capabilities of transducer.
