The device UVS-30 is available in two versions, differing operating conditions and operating variables Maximum capacity (IVC) size.
Device UVS-30 type 1 consists of a measuring sensor and a strain gauge and is intended for use as a reference means in the production and operation of load appliances middle class accuracy.
Device UVS-30 from the execution unit 2 comprises a measuring and (U-16) tenzorezistornyh sensors and is designed for use as a load cell platform scale element type dispensers etc.
Structural features of UVS-30
Strain gauge sensor (Figure 1) UVS-30 is composed of an elastic element in steel with strain gauges glued to it and the flange. The internal cavity of the sensor is sealed. The force is applied to the sensor through the flange, included in the package.
