LCA-D LOAD CELL TRANSMITTER

LCA-D load cell amplifiers weigh various tanks and similar units and enable remote monitoring of all measurements in the most cost-effective way possible. Weights of one or more unit’s being weighed by the load cells can either be viewed on the LCA-D devices, which are mounted next to the weighing system, and they can also be monitored via a remote computer. LCA-D distinguishes itself by enabling computerized setup of all parameters through the Modbus communication protocol.

This enables monitoring and programming of several LCAs, which are connected to the same communication bus, from a single control point such as a PC or a PLC. Two Windows TM-based software programs have been developed for communication with the LCA devices. The first one, Dlms_VP (Digital Load Cell Measurement System Virtual Panel) can communicate with only one LCA device and setting up all parameters remotely. The second, Dlms_NW (Digital Load Cell Measurement System Network), gives way to viewing more than one LCA amplifiers at the same time. The aluminium cast housing makes the device serviceable even under dusty, humid and corrosive conditions.
