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. The grease controller includes a tangible storage medium which stores executable instructions to change the state of the prime indicator based on the sensor data and to delay changing the state of the prime indicator for the delay period after the controller determines the grease dispensing device is not primed with grease.

A method and a system for monitoring a mechanical system, the mechanical system including a lubrication system provided with a reservoir containing a lubricating liquid, with a lubrication circuit designed to lubricate the mechanical system, as well as with a particle detection device arranged in the lubrication circuit. The detection device makes it possible, in particular, to count the number of particles flowing through the lubrication circuit and/or the flow rate of the particles. Comparing that number or that flow rate with a first threshold makes it possible to determine a risk of damage affecting the mechanical system and to anticipate the maintenance or reinforced monitoring operations that possibly need to be performed.

A modular digital filter, regulator and lubricator (FRL) connector and system are provided. The modular digital filter, regulator and lubricator connector and system are especially suitable for use in improving compressed air quality so as to extend the life of tools and machines which are connected to the FRL devices. The connector device and system allows for a quick and efficient connection with respect to both electronics and air lines and reduces problems that arise from wire pig-tailing or accidental disconnection of the FRL. The device and system may have digital, visual and audible warnings with respect to the quality of air passing through the system and to the tools and machines.
