1. A lubrication system including:
a progressive distributor; and
at least one pressure sensor,
wherein the progressive distributor includes a housing block having a lubricant inlet, a plurality of lubricant outlets, a plurality of piston bores fluidically connected to the lubricant inlet, each of the plurality of piston bores having a first outlet bore and a second outlet bore, and a metering piston in each of the plurality of piston bores,
wherein each of the metering pistons is displaceable in a respective one of the plurality of piston bores to uncover either the first outlet bore or the second outlet bore,
wherein a first one of the plurality of piston bores is fluidically connected to at least a second one of the plurality of piston bores by a first connecting bore and the second one of the plurality of piston bores is fluidically connected to at least a third one of the plurality of piston bores by a second connecting bore,
wherein the pressure sensor is disposed at an inlet of the progressive distributor upstream of the plurality of metering pistons with respect to a lubricant flow direction and configured to determine a lubricant pressure, and
wherein the pressure sensor is integrated into the housing block of the progressive distributor.
