VPG – Ring Torsion Load Cell
Brand: VPG
Description:
The RLC is a low profile, high-performance stainless steel ring torsion type load cell. The fully welded construction and glass-to-metal cable entry ensure that this product can be used successfully in harsh environments found in the food, chemical and allied process industries. This product is suitable for small and medium platform scales, hoppers and process weighing. This product meets the stringent Weights and Measures requirements throughout Europe and the USA.
