SLP845 Hermetic Single Point Load Cell
The SLP845 is the ideal solution for scales, packaging and process weighing where a hermetically sealed stainless steel load cell is required for harsh chemical and washdown environments. Due to the low profile the integration into any system is easy. The broad capacity range and large platform size allows wide application in industrial weighing applications.
Wash Down Applications
SLP845 is the right choice for the food or pharmaceutical industry where daily wash down is required. It provides best weighing performance in a hermetically sealed stainless steel load cell. Thus it is ideal for stainless steel scales or general weighing applications where the highest grade of IP protection and corrosion resistance is required.
Off-Center Compensation
One load cell can be used to support a weighing platform and, due to the off-center load compensation, the SSH will weigh within tolerance regardless of load application point.
Robustness
SLP845 is an extremely robust single point load cell suitable for almost all industrial environments. It allows 50% static overload without compromising the weighing performance.
