Guide for Load Cells

August 2001, issue 2ENDEFRRS


Weighing instruments (WIs) are often constructed from typical modules such as indicator, mechanical construction and load cell. Therefore, type examinations are often performed on representative modules which can be tested separately.
For non-automatic weighing instruments (NAWIs) the basis of this modular concept is laid down in OIML R 76, No 8.2, and EN 45501, No 8.1, respectively, where the following relevant cases are mentioned:
• testing of the instrument as a whole is difficult or impossible
• the module is manufactured and/or placed on the market as a separate unit to be incorporated in a complete instrument
• the applicant wants to have a variety of modules included in the approved pattern.
