LCA-X LOAD CELL TRANSMITTER
LCA-X 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 units being weighed by load cells can be measured by LCA-X devices in the measurement field and monitored via a remote computer. The amplifier itself does not have a dLCA-X distinguishes itself by enabling computerized setup of all parameters through the Modbus communication protocol. Remote access to settings is provided via the embedded Modbus protocol.isplay.
This allows monitoring and programming of several LCA devices connected to the same communication bus from a single control point, such as a PC or PLC.Two Windows™-based software programs have been developed for communication: Dlms_VP (Virtual Panel), which communicates with a single LCA device for remote setup, and Dlms_NW (Network), which allows viewing multiple LCA devices simultaneously. The aluminum cast housing makes the device serviceable even under dusty, humid, and corrosive conditions.
