Technology
The robust digital load cell is based on a capacitive measurement principle where a non-contacting ceramic sensor is mounted inside the load cell body. As the load cell contains no moving parts and the sensor is not in contact with the load cell body, the load cell tolerates shocks, torsion, and very high overloads and sideloads. Therefore, the mechanical installation of the load cell can be done without expensive and complicated mounting kits and overload protection devices.
The electrical installation of the digital load cell is pure plug-and-play as the signal from the non-contacting sensor is directly converted, compensated and calibrated by a microprocessor to a digital load cell output in grams, kilograms, or Newton. Measurements and status codes are transmitted as RS485 data on a single wire coaxial cable (RG-58) which may be up to 100 meters long. The load cell cable can be replaced on-site if necessary.
The technology and mechanical design of the Eilersen load cells is covered worldwide by a number of patents.
