Bridge Amplifiers for PowerLab
These bridge amplifiers are single- or multi-channel bridge amplilfiers designed to allow the PowerLab to connect to most DC bridge transducers, 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.

FE221 Bridge Amplifier
A single-channel, non-isolated bridge amplifier designed to allow the PowerLab to connect to most DC bridge transducers.
FE228 Octal Bridge Amplifier
An eight-channel, non-isolated bridge amplifier designed to allow the PowerLab to connect to most DC bridge transducers.
FE244 Quad Bridge Amplifier
A four-channel, non-isolated bridge amplifier designed to allow the PowerLab to connect to most DC bridge transducers.
Features
- Low-drift instrumentation amplifier
- Software-controlled zeroing
- Wide amplification range (±200 µV to ±5 V in 14 steps) for use with a wide range of transducers
- A high impedance input (2 x 1 MΩ single-ended, 2 MΩ differential) ensures that the Bridge Amp will not load the transducer
- Overload light to indicate whether the attached transducer is operating correctly or incorrectly
Applications
Used for measuring force, displacement and physiological pressures. Ideal for multi-channel isolated tissue studies.
Requirements
- PowerLab 26- and 35-series systems (include LabChart software abd Scope application)
