Single point load cell, Model F4885
The model F4885 single point load cells are a range of aluminium single point load cells suitable for a wide range of applications. Thanks to their standardised geometry and simple design, they can be easily installed in all types of scales.
The model F4885 load cells are adapted to the special requirements of checkweighers and feature a particularly short settling time, so that the weight of the goods being recorded can be determined as quickly as possible.
The load cells are also suitable for use in sectors such as industry, commerce, medicine and research.
The model F4885 single point load cells also feature high accuracy and react quickly. They are also insensitive to lateral and corner loading.
The load cells are easy to handle due to their simple force introduction. This is made perpendicular to the geometry.
