Chain tension sensing device includes a hollow enclosure, a sensor mounted in a stationary position within enclosure and a member mounted for a reciprocal movement in a substantially linear direction relative to the sensor. The member includes a chain engaging first portion, a second portion mounted for reciprocal movement and a sensor target disposed on a distal end of the second portion. A compressible resilient member is mounted in abutting engagement with at least a rear surface of the first portion. Chain take-up attains tension thereon generating force and moving the member towards the sensor so as to position the sensor target in operative sensing alignment therewith. Chain let-up causes the compressible resilient member to move the member in an opposite direction, removing the sensor target from the operative sensing alignment with the sensor.
