摘要： An apparatus for providing an indication of the weight of a load on a vehicle or on any part of the vehicle comprising a sensing means operable between a moving part and a stationary part of the vehicle and sensing the distance between the stationary part and the moving part, a transducer unit converting any alteration of the said distance detected by the sensing means into a proportional electric property and an electrical gauge receiving the output from said transducer unit characterised in that the transducer unit includes a spindle associated with a light beam, a shutter for the light beam and a photoelectric cell receiving the light beam the arrangement being such that alteration of the said distance detected by the sensing means is followed by proportional rotation of the spindle which causes the light beam to be proportionately modified by the shutter in a manner which is detectable by the photoelectric cell and converted into a proportional electric property.
