AS200706 - Bridge Amplifier with Linearity Correction

The AS200706 is a small compact board for 3-wire systems providing a 4mA - 20mA current output with adjustable linearity correction. The unit has individual multi-turn potentiometers for the precise setting of Zero, Span and Linearity without the need of a computer. This unit 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 connected to board via soldering or SIL sockets (standard).
