FA07-A2 2 Channel Amplifier RS485


The amplifier is available in an aluminium housing. Weighing controllers are available in plastic, aluminium and explosion-proof housings to order. The weighing controller has built-in high performance devices, precision amplification line, internal voltage stabilisation of the line, constant current supply bridge, voltage and current conversion, impedance adaptation, linear compensation, temperature compensation, etc. The MV signal of the resistance-strain load cell is amplified into a standard current and voltage signal output of 4-20mA, 0-5V, etc., which can be received and processed directly with the control system such as the AD module of the peripheral PLC, the transmitter has The transmitter is equipped with the functions of external zero adjustment and external gain adjustment for standard signals.

Installation size



Accurate measurement with matching display

The output of the force measuring and weighing sensor itself is an MV signal, which needs to be amplified and

convertedto display numerical values or output signals to the upper computer, PLC, etc.




Product Application
