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