Probe unit for automatic determination of quality properties of meat
First Claim
1. A probe unit for automatic determination of quality properties in meat comprising:
- an insertion probea measuring means in a free end of said insertion probe,a double-acting drive cylinder unit for reciprocatingly moving said insertion probe, said double-acting drive cylinder unit including a pipe,a piston rod arranged for sliding reciprocation in said pipe and extending through both ends of said pipe and having a overall length at least twice the length of its stroke, the piston rod having a front end forming said insertion probe and a rear end,a position meter, located at said rear end of said piston rod, producing electric signals indicative of the position of the measuring means with respect to the pipe.

Abstract
A probe unit for automatic determination of quality properties in meat comprises an insertion probe with a measuring device, such as a light reflection meter, at a free end of the probe. A double-acting drive cylinder unit reciprocatingly moves the insertion probe and consists of an interior pipe surrounded by an outer impact resistant pipe. A tubular piston rod is reciprocatingly slidably arranged in the interior pipe. The piston rod extends through both ends of the interior pipe and has an overall length at least twice the length of its stroke. The front end of the piston rod serves as the insertion probe while the rear end of the piston rod carries or forms part of a position meter producing electric pulses indicative of the position of the light reflection meter with respect to the interior pipe. The position meter includes a signal generator with a toothed wheel engaging a toothed rack and generates pulses applied to a pulse counter. The signals from the measuring device represent the type and/or quality of the material in which the measuring device is present at any time. The probe unit is sturdy and reliable in operation and requires little space, in particular in transverse direction, and therefore is appropriate for incorporation in automatic systems with many probe units.
