3-Wire Universal Bridge Amplifier for Load Cells AS7539A
The AS7539A is a universal 3-wire amplifier providing five modes of operation (current/voltage and unipolar/bipolar outputs). It has individual multi-turn potentiometers for the precise setting of Zero and Span and is also available with mid. zero output (12mA for example) for compression / tension transducers. The inputs provide EMI-/RF-suppression. Transducer wires can be easily clamped onto the board. Two additional extension boards (ASM1) are also available providing multiple transducer processing (allowing up to 4- or 8-amplifiers), along with rugged aluminium enclosures offering IP66 protection.
