The AS600-series simulates a full-bridge transducer, including load cells, strain gauges, pressure sensors, extensometers and other bridge-based sensors. The dual attenuator network provides a symmetrical output that accurately replicates a full active bridge and can be switched between positive, zero and negative outputs.

Ideal for transducer testing, amplifier calibration, fault finding, system commissioning and R&D. Housed in a robust IP54-rated die-cast aluminium enclosure for reliable use in both laboratory and field environments.
