The DSC is a high performance digital signal conditioner with a host of additional features for the precision measurement of strain gauge based transducers.
The DSC is available with a RS485 or RS232 output format, making it suitable for "one-to-one" or mutli-drop systems.
Including the DSC into load cell based applications enable the building of very high accuracy load cells, using the built in linearisation and temperature compensation facility.
The DSJ1, single channel junction box and DSj4, 4-channel junction box are available to assist with simple on-site installation and commissioning.
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.
