1. Transportation and installation.
German HBMRSCC series load cellIt is suitable for measuring axial loads in the tensile direction. Because they provide highly accurate static and dynamic load measurements, they must be handled with great care. Special care must be taken when transporting and installing the equipment. Dropping or tapping the sensor may cause permanent damage.
The permissible limits for mechanical, thermal and electrical stresses are listed in the installation guide for the load cells of the RSCC series. These factors must be taken into account when planning a measurement setup, during installation, and during eventual operation.
In addition, incorrect handling or installation may result in explosion-proof failures, and the relevant installation regulations must be complied with during the installation process, and the installation conditions quoted in the certificate of conformity and/or type examination certificate must be complied with.
2. Structure and working principle.
The star element is a steel component, to which a strain gauge (SG) is suitable. The SGs should be arranged in such a way that when the load is applied to the sensor, two SGs are stretched and the other two SGs are compressed.
3. Ambient temperature.
RSCC compensates for the effect of temperature on zero signal and sensitivity.
In order to obtain the best measurement results, the nominal (rated) temperature range must be observed. Temperature-dependent measurement errors are caused by heating, such as radiant heat or side cooling. Radiation shielding and all-round insulation can produce significant improvements, but must not create a force diversion.
4. Humidity and other environmental conditions.
The German HBMRSCC series load cells are hermetically sealed and therefore completely insensitive to humidity and humidity. The sensor achieves IP68 protection according to DIN EN 60529 (test conditions: 100 hours under 1 m of water). However, the load cell must be protected against permanent moisture.
Load cells must be protected from chemical attack on the sensor body steel or electrical training. For stainless steel load cells, please note that acids and all materials that release ions can also corrode the stainless steel and its welds. If any corrosion is present, this can lead to the failure of the load cell. In such cases, appropriate protective measures must be taken.
5. Accumulation.
Dust, dirt and other foreign objects must not accumulate enough to transfer part of the measured force and thus invalidate the measured value (force splitting).
