Bridge Amplifier Accessories

The FE221, FE224 and FE228 Bridge Amps are designed to allow the PowerLab to connect to most DC bridge trans-ducers, including commonly available force transducers, temperature probes, light meters, displacement transducers, pressure transducers, and similar devices. They are capable of supporting various powered transducers, and certain low-impedance unpowered transducers.

Compatibility:
An overload light on the front of each input indicates whether the attached transducer is operating correctly or incorrectly. If the overload light is on the transducer is incompatible with the Bridge Amp and should be disconnected. Contact your nearest ADInstruments rep for assistance.

The Bridge Amps are compatible with PowerLab 35 series.
