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, wherein the chamber comprises a plurality of channels formed through the housing, the channels being configured to maintain a lubricant pressure in the chamber above a predetermined pressure value if the lubricant is being supplied to the chamber, and wherein the predetermined pressure value being a reference value for determination of lack of the lubricant supply into the chamber,
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; and
a pressure transducer configured to measure the lubricant pressure in the chamber of the housing and generate an output pressure signal related thereto.
