Bearing seat sensor / bearing seat sensor SM41A
Product Categories Bearing seat sensor
The bearing seat sensor is mainly installed under the bearing seat, and can also be used in other structural forms. It is a special sensor that mainly measures the bearing capacity of a bearing seat. The structural principle is a shear-type resistance strain sensor with fixed supports at both ends and a central load. High-quality alloy steel is selected as the elastomer and foil resistance strain gauge is used as the sensitive conversion element. The bearing seat is installed in the middle of the sensor, and the two ends of the sensor are fixed on the base. When the bearing seat is loaded, the load is transmitted to the base through the shear elastic beams at both ends, and a strain proportional to the load is generated in the elastic beam, which is converted into a corresponding electrical signal through the strain gauge.
