DATA SHEET FMS Tension Control / Force Sensors LMGZ-Series Highly precise, stainless steel force measuring bearing l Wide measuring range with highest resolution Measuring range 100:1 Accuracy class ±0.3% a wide range of applications 7 sizes with nominal force from 33 to 25'000 N (7.5 to 5'620 lbf.) Robust and durable Overload protection up to 20-times nominal force, full stainless steel LMGZ-Series The force measuring bearings of the LMGZ-Series, designed for the measurement of tension on continuous material processing lines where live shaft idler rolls are utilized. The accuracy class of 0.3% and the measuring range of 100:1 allows reproducible, highly precise measurements throughout the industry. The mechanical overload protection of up to 20-times the nominal force provides unsurpassed robustness. With the superior performance of the LMGZ-Series, accurate tension readings are obtained even with low web wrap angles and high roll weights. For installations where a Pillow Block mount is required the optional bracket can be utilized. Functional description The LMGZ-Series force measuring sensor combines the bearing seat and the force sensor within the same housing, thus minimizing the required installation space. The substantial overload protection translates to eliminated/minimized calibration issues due to machine upset conditions. The movement of the bending beam, which is proportional to the applied force, is detected by strain gauges arranged in a full bridge circuit and then converted into an electrical signal. This simple measurement principle delivers precise results even with low material tension and small web wrap angles. The Red Point, as located on the sensor body, should be aligned with the direction of the resultant force due to web tension.

Overload protection with block Overload protection with pins There are 2 design Typees of overload protection devices: block or pins. 1) distance ring, in scope 2) thinner clip ring, in scope Series 1 self-aligning ball bearing Series 2 spherical roller bearing Various types of bearings can be utilised with an LMGZ series sensor. FMS recommends the use of self-aligning versions to compensate for shaft alignment errors and to avoid measuring inconsistencies.

LMGZ-Series : Dimensions 3) actually 27 mm, but with grinded clip rings space for 28 mm bearing 1) Types available only in H15 version

DATA SHEET FMS Tension Control | Force Sensors | LMGZ-Series GMGZ-installation brackets When it is not conducive to mount the sensors directly onto the machine frame, the GMGZ Series supports are available for all sizes of LMGZ sensors. They are made of durable cast iron and can either be supplied blank (customer drills the sensor mounting holes in them to optimise the positioning of the sensor) or with a 360° clock-wise pattern of pre-drilled mounting holes. Mounting positions between 1 and 2 are not possible as the support foot interferes with the sensor connector. GMGZ-Series :...
