Abstract: A control apparatus that controls a resolution according to a signal of a motor is provided. The apparatus comprises a measurement unit configured to measure a voltage and an electric current of the signal, an amplification unit comprising a first variable resistor, and a micro control unit (MCU) comprising first, second, and third lookup tables. The amplification unit is configured to amplify the signal according to a first gain corresponding to a resistance value and generate an output signal. The MCU is configured to set the resolution, divide the signal, generate the output signal, set a measurement range corresponding to a first gain, and control the resistance value. The MCU is configured to control the resistance value according to a comparison between the set measurement range, comprising a range of voltages proportional to a magnitude of the gain, and a range of possible measurement set corresponding to the signal.

Abstract: Systems and techniques are disclosed to sense a temperature and a flow rate of oil in a compressor. A compressor includes: a casing; a frame on the casing; a fixed scroll on the frame; an orbiting scroll supported by the frame and defining a compression chamber while engaging the fixed scroll; and a crank shaft. The crank shaft transfers, to the orbiting scroll, a rotational force of a motor. The casing includes: a main housing including a refrigerant discharge passage and an oil passing passage; and a sub-housing including a refrigerant discharge port and an oil channel, which includes an oil reservoir, that each face the main housing. A sensor module attached to a sensor receptor in the sub-housing includes: a sensor housing covering the sensor receptor; and an oil sensor and a temperature sensor located on the sensor housing that each protrude towards the oil reservoir.
