PW4M-OP Single Point Load Cells for Precise Weighing of Masses from 300 g to 5 kg

The small PW4M-OP single point load cells are available in different options with maximum capacities ranging up to 5 kg. They offer extremely precise measurement results as well as an optimal price-to-performance ratio. Since they are approved in legal-for-trade applications and have an extremely high precision (accuracy class C3), these load cells are especially well-suited for batching, filling, and controlling tasks with small-sized packages, such as those used in the pharmaceutical, cosmetics, or food industries. The PW4M series is the only series of strain gauge-based single point load cells available with an OIML R60 test certificate for a maximum capacity of 300 g. Another special feature of the load cells is the PW4M-OP’s novel overload protection, which enables it to reliably withstand overloads of up to 10 times its maximum capacity.

Accuracy Class: C3 according to OIML R60
Minimum verification interval: up to 0.05 g
Maximum capacities: 0.3 kg up to 5 kg
