KMRplus Strain Gauge-Based Force Washers: 11 Capacities and IP68 Degree of Protection
The KMRplus, like common washers, are suitable for mounting onto bolted or screwed connections. Sensors are available for threads ranging from M6 to M42 (forces of up to 2 MN). The KMRplus force washers are fitted with special strain gauges that cover a very wide angular range, making them highly insensitive to bending moments. The sensors are suitable for both fast and static measurement tasks due to the use of strain gauge technology and their high stiffness.
The sensors are not only made of stainless steel but are also hermetically sealed (IP68 degree of protection) to allow force measurements under harsh ambient conditions or outdoors. They ensure maximum immunity to electromagnetic interference owing to their cable and sensor-housing design that forms a Faraday cage.
The force introduction washers included in the scope of delivery ensure good force introduction. Various connector plugs and cable lengths allow adaptation to the respective measuring task.
The KMRplus force washers operate in the force shunt, hence calibration is required after installation to obtain quantitative results.
