Anderson-Negele L-Cell®
Bolt-on Load Cell | Food, Beverage and Dairy
Weighing Systems, Level Sensors
Bolt-on dual-axis shear force sensors for all types of vessels with metal supports and skirted silos.
L-Cell® load cells are extremely durable, reliable and compact sensors for cost-effective and dependable quantity measurement in all types of vessels. They can be mounted or retrofitted at any time on vertical supports, horizontal beams, or skirted silos. Measurement inaccuracies due to angles of repose, accumulations or compaction are reliably avoided.
Depending on the type of container and its substructure, the sensors are simply bolted onto the supports. Integrated strain gauges transmit stress changes in the metal, which are caused by even the slightest changes in the container contents, as a measurement signal to the control system.
- Extremely long-lasting: virtually “indestructible” due to material fatigue life >20 million measuring cycles, high shock resistance and weather insensitivity.
- Easy mounting: can be easily bolted on or retrofitted. Emptying or lifting the vessel is not necessary.
- Easy calibration: An empty vessel is not required, precise calibration can take place at any filling level.
- Always accurate: Unlike other level sensors, thermal or density change does not affect the measurement result.
- Can be relied upon: Kistler-Morse pioneered load cell technology. This is still the standard for load and content measurement in many industrial sectors.
Microcell® and L-Cell® are extremely long-lasting, reliable, and compact sensors for cost-efficient inventory measurement in all types of vessels with a leg support structure and skirted silos. This avoids measurement inaccuracies reliably due to material characteristics like the angle of repose, rat-holing, bridging, moisture content, compaction.
Depending on the vessel type, the sensors are mounted with bolt-on technology on the structural support members and shear beams support or structural skirt.
Integrated strain gauges transmit stress changes in the metal caused by any fluctuations in the container contents, as a measuring signal to the control system.
Simple inventory control for all vessels
- Durable, reliable measurement: Kistler-Morse pioneered bolt-on technology for storage vessels and silos. This method is still the standard way of measuring load-induced strain for precise quantity measurement in bulk vessels in many markets.
- Extremely robust: With a fatigue life of >20 million measuring cycles, high shock resistance, and weather insensitivity, Microcell® and L-Cell® are virtually “indestructible” for almost all applications.
- Simple installation, even for retrofitting: Using the installation set and drilling template, the sensors are simply bolted to the structural supports or skirts and connected to the controller via a junction box.
There is no need to empty, lift or modify the vessel. - Easy calibration: An empty vessel is not required. Precise calibration can take place at any fill level.
- Easy to replace: If damaged due to, e.g., mechanical impact, sensors can be easily replaced on-site.
