The Alfa Laval Weighing System with Compression Load Cells features patented digital capacitive technology that has a non-contact capacitive sensor mounted inside the load cell body.

Each weighing system consists of: Several load cells, including load cell modules, an electronic output module, which can be either analogue or digital and control modules for the load cells and cable. To ensure robust and reliable connection between the tank and the load cells, Alfa Laval offers an additional range of tank legs that fits to the load cells.

Factory pre-calibration does away with time-consuming onsite adjustments during commissioning. No costly, complicated mounting kits, stay rods or overload protection devices. Just precise load cell weighing and management at its best.

When a load is applied, a portion of the load is transmitted to each load cell, which sends an electrical signal proportional to the load sensed to the control module. The control module converts the signals to an accurate weight reading.

Because there is no contact between the capacitive sensor and the load cell body, the load cells are largely unaffected by overload, side loads, torsion, shocks and welding voltages. This makes straightforward mechanical load cell installation possible. A proprietary application-specific integrated circuit (ASIC) in the load cell converts, compensates and calibrates the output from the ceramic load cell weight sensor, enabling plug-and-play operation and accurate compression load cell measurement.
