The DCELL is a high performance digital signal conditioner for the precision measurement of strain gauge based transducers.

The Micro Miniature PCB is designed to fit inside the majority of sensors, providing a 'digital' load cell with the benefit of very high stability and an RS485 output.

LCM Systems offer the DCELL as a standalone product or built into most of our load cell based products. Including the DCELL into load cell based product enables the building of very high accuracy load cells, using the built in linearization and temperature compensation facilities.

LCM Systems can also supply PC based software packages, specially written to interface with DCELL based load cells and pressure transducers. Please contact our technical department to discuss your requirements.

For applications where it is not possible to fit the DCELL within the transducer, there is an in line housing available (Model ILE).

Suggested Instrumentation

The DCELL offers a RS485 digital output (in various protocols). LCM Systems can offer the DCELL as part of a complete system, including sensors (and can be integrated into many sensors) and bespoke software, written specifically for your application. The software is usually developed using the Visuallink software platform. Contact LCM Systems to discuss your software/application requirements.
