Explanation:
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 units 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. Remote access to and setup of parameters are made possible with the use of the embedded communication protocol, Modbus. This enables monitoring and rogramming of several LCAs, which are connected to the same communication bus, from a single control point such as a PC or a PLC.
Two WindowsTM based software programs have been developed for communication with the LCA devices. The first one, Dlms_VP (Digital Load Cell Measurement System Virtual Panel) is capable of communicating with only one LCA device and setting up all parameters remotely. Dlms_NW (Digital Load Cell Measurement System Network), on the other hand, gives way to viewing more than one LCA amplifiers at the same time. With Dlms_NW, a multiple number of computers connected over a network can display the same data.
The aluminum cast housing makes the device serviceable even under dusty, humid and corrosive conditions.
