1. A device for monitoring a lubrication of a tool, the device comprising:
a housing comprising:
a lubricator connector configured to connect the housing to a lubricator and comprising a lubricant inlet opening,
a chamber configured to receive a lubricant from the lubricator through the lubricant inlet opening,
a tool connector configured to connect the housing to a lubricant fitting of a tool and comprising a lubricator outlet opening through which the lubricant leaves the chamber;
a pressure transducer configured to measure a lubricant pressure in the chamber of the housing and generate an output pressure signal related thereto;
a controller configured to:
determine, based on the output pressure signal, an abnormal lubrication of the tool by the lubricator;
determine, based on the output pressure signal, a lack of the lubricant supply from the lubricator if the lubricant pressure being measured in the chamber is below a predetermined first pressure value;
wherein the chamber comprises a plurality of channels formed through the housing and fluidically interconnecting the lubricant inlet opening, the lubricant outlet opening and an opening through which the pressure transducer is inserted into the chamber; and
wherein the plurality of channels comprises:
a first channel extending through housing from the lubricant inlet opening towards the opening through which the pressure transducer is inserted into the chamber;
a second channel being substantially parallel to and distanced from the first channel;
a third channel being substantially perpendicular to and interconnecting the second channel and the first channel; and
a fourth channel being substantially perpendicular to the second channel and connecting the second channel to the lubricant outlet opening.
