Explanation
LCA-X strain gauge amplifiers weigh various tanks and similar units and allow remote monitoring of all measurements in the most economical way.
The weights of one or more load cell devices can be measured by the LCA-X devices in the measurement field and monitored by a remote computer. The amplifier itself does not have a display.
LCA-X is distinguished by the possibility of computerized setting of all parameters through the Modbus communication protocol. Remote access to parameter settings is provided via the built-in Modbus communication protocol. 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 Windowsâ„¢ based software products have been developed to communicate with LCA devices:
Dlms_VP (Digital Load Cell Measurement System Virtual Panel) – communicates with only one LCA device and adjusts all parameters remotely
Dlms_NW (Digital Load Cell Measurement System Network) – allows viewing of more than one LCA device simultaneously. With it, multiple networked computers can display the same data
The aluminum body of the device makes it serviceable even in dusty, humid and corrosive conditions.
