  • Publication number: 20210140584
    Abstract: A grease dispensing device includes a grease drive system for moving grease through grease passaging. A sensor is arranged to sense grease in the grease passaging and to generate sensor data related thereto. After a delay period, a prime indicator changes between first and second states based on the sensor data to indicate whether or not the grease dispensing device is primed with grease. The grease dispensing device also includes a grease controller operatively connected to the sensor and the prime indicator. The grease dispensing device monitors the sensor data to determine whether the grease dispensing device is primed with grease and controls the operation of the prime indicator accordingly.

  • Patent number: 9625092
    Abstract: A battery-powered, handheld grease gun for dispensing lubricant. A pump mechanism driven by a motor is in communication with the lubricant and has a supply port for dispensing the lubricant at a lubrication point. A sensor monitors the pump mechanism of the motor. A display displays information indicative of the monitored condition of the device, such as volume of lubricant dispensed. A processor responsive to operator input selectively energizes the motor to drive the pump mechanism to dispense lubricant.
