Patent ID: 7549324

Claim:
Consistency transmitter capable of measuring the consistency and viscosity of matter, comprising a measuring element fastened to an end of a torsion shaft, a drive shaft, differential elements connecting the torsion shaft and drive shaft to each other, and an insertion pipe and valve combined with the insertion pipe for the purpose of inserting the consistency transmitter into a process to be measured while said process is operating, wherein: a motor of the consistency transmitter comprises a direct drive stator and rotor, rotation axes of which are coaxial with the rotation axes of the measuring element, torsion shaft, differential elements, drive shaft and the insertion pipe, whereby the consistency transmitter has no separate motor; instead the stator is integrated into a stator base and the rotor is integrated into drive shaft, so that the drive shaft also functions as a rotor shaft; the drive shaft is fit with drive shaft bearings on a drive shaft body and the drive shaft bearings are also arranged to act as rotor bearings; the drive shaft and the rotor have common covers and seals; the drive shaft is comprised of one piece and comprises an end that protrudes into the process being measured; and the torsion shaft is bearing-mounted inside the drive shaft.
