The Load Cell Amplifier is a precision amplifier for conditioning the milivolt output from a Lad Cell so that it can be given as an input to the microprocessor based Interface Unit. Alternatively the output can also be given to the analog input module of a PLC or DCS system in the form of standard 0 - 10V voltage signal or 4 - 20mA current loop signal. In addition, the unit has a built in 10 Volts precision reference generator, which is used for excitation of the Load Cell. These amplifier units are extremely stable and accurate for long term measurement applications and can also be calibrated to suit the Load Cell response characteristics so that maximum sensitivity is available in the measurement range.
