Model 75 Precision Low Profile Load Cell DESCRIPTION Honeywell’s Model 75 load cells are engineered for applications Model 75 measures tension/compression and must be used on a such as materials or product fatigue testing, which involve an smooth flat surface to achieve rated specifications. The tension/ extremely large number of cycles or occasional overload condi- compression Model 75 is designed with the threaded hole run- tions. These fatigue rated load cells have load ranges from 50 lb ning completely through the center of the cell. Model 75 utilizes to 200,000 lbs and achieve a non-linearity of 0.1% full scale. The two stabilizing diaphragms, which are welded to the sensing superior design of these bonded foil, strain gage compression member to reduce off-center and side-loading effects. and/or tension load cells permits a fatigue life of 1 billion cycles (zero to full scale).

C dimension varies on high ranges. Consult factory. 2. Allowable maximum loads - maximum load to be applied without damage.3 3. Without damage - loading to this level will not cause excessive zero shift or performance degradation. The user must consider fatigue life for long term use and structural integrity. All structurally critical applications (overhead loading, etc.) should always be designed with safety redundant load paths. 4. Interconnecting shunt cal. 1 terminal with shunt cal. 2 terminal provides 50 % (unamplified units), 75 % (4 mA to 20 mA three-wire units) or 80 % (voltage amplified units) of full scale output for quick calibration.
