Description
Model F1227 Compression force transducer with strain gauges
For rated forces up to 500,000 lb [2,224 kN]
The model F1227 compression force transducer with strain gauges offers high accuracy and is suitable for both static and dynamic force measurement in the direct force flow.
The spherical cap with spherical surface, also known as load introduction button, serves to absorb compression forces and ensures axial, perpendicular and centred force introduction. The force is thus transmitted centrally and evenly into the instrument. This enables precise measurement of the actual compression forces in a wide variety of applications.
The measuring spring is elastically deformed by a compression force introduced in the force direction. The resulting mechanical tensions are measured by the strain gauges, converted into an electrical output signal and output as an mV/V signal.
With its robust design, the instrument ensures excellent stability and durability under high loading and is ideally suited for harsh operating conditions in industrial automation, test bench construction as well as production plants.
Due to its low installation height, the instrument is suitable for use in confined mounting situations and can be easily integrated into existing plants.
The tightly hermetically sealed instrument made of stainless steel is splash-proof and guarantees reliable operation even under harsh operating conditions.
