Load measuring device UVS-20 - a product designed to convert an applied force of gravity in the mass of the weighing, and can be used as a retrofit kit for load product, vesodoziruyuschih systems, as well as exemplary means for verification during manufacture and operation of small portable car pokolesnogo weighing scales for middle-class accuracy.
Maximum capacity - 20t.
Weighing time - not more than 10s.
Power supply - AC mains 220V, 50Hz.
Power consumption - less than 20W.
- Strain gauge sensor - Ø120mm × 80mm;
- Measuring Unit - 270 × 220 × 200mm.
- Strain gauge sensor - no more than 4 kg;
- The measuring unit - no more than 1kg.
UVS-20 device is available in two versions that differ Operating conditions and the values of the weighing capacity (IVC) size.
Device UVS-20 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-20 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-20
Strain gauge sensor (Figure 1) UVS-20 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.
