Abstract: A compressor may include a shell containing a motor, a compression mechanism and a lubricant sump. The compressor may also include first and second temperature sensors, and a control module. The first temperature sensor may be at least partially disposed within the lubricant sump and may measure a first temperature of a lubricant at a first position. The second temperature sensor may be at least partially disposed within the lubricant sump and may measure a second temperature of the lubricant at a second position that is vertically higher than the first position. The control module is in communication with the first and second temperature sensors. The control module may determine a first difference between the first temperature and the second temperature. The control module may determine whether a liquid level of the lubricant in the lubricant sump is below a predetermined level based on the first difference.

Abstract: A compressor includes a shell, a first temperature sensor, a second temperature sensor, and a control module. The shell includes a motor, a compression mechanism and a lubricant sump. The first temperature sensor is at least partially disposed within the shell and configured to measure a first temperature of a lubricant at a first position. The second temperature sensor is at least partially disposed within the shell and configured to measure a second temperature of the lubricant at a second position that is vertically higher than the first position. The control module is in communication with the first and second temperature sensors and configured to determine a first difference between the first temperature and the second temperature. The control module is configured to determine whether a liquid level of the lubricant in the lubricant sump is below a predetermined level based on the first difference.

Abstract translation: 压缩机包括壳体，第一温度传感器，第二温度传感器和控制模块。 壳体包括马达，压缩机构和润滑油槽。 第一温度传感器至少部分地设置在壳体内并且构造成在第一位置处测量润滑剂的第一温度。 第二温度传感器至少部分地设置在壳体内并且构造成在垂直于第一位置的第二位置处测量润滑剂的第二温度。 控制模块与第一温度传感器和第二温度传感器连通，并且被配置为确定第一温度和第二温度之间的第一差值。 控制模块被配置为基于第一差异来确定润滑剂油底壳中的润滑剂的液位是否低于预定水平。
