Description
Single point load cell, Model F4818
The model F4818 single point load cells are a series 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 F4818 load cells are used in various are as such as industry, commerce, medicine and research.
The most common application area is in precision, industry and bench scales as well as belt weighers, to measure the weight of products (e.g., food, bulk material, feed). Load cells are also used in the packaging industry, manufacturing as well as material testing.
The single point load cells feature high accuracy and a quick reponse. Moreover, they are insensitive to lateral and corner loads.
The load cells are easy to handle due to their simple force introduction. This is made perpendicular to the geometry.
