A four-channel, non-isolated bridge amplifier designed to allow a C Series Front End Inteface or traditional PowerLab to connect to most DC bridge transducers. ADInstruments Bridge Amps are single-channel or multi-channel, non-isolated bridge amplifiers designed to allow a C Series Front End Interface or traditional PowerLab to connect to most DC bridge transducers, including commonly available force transducers, temperature probes, displacement transducers, pressure transducers, and similar devices. They are capable of supporting various powered transducers, and certain low impedance unpowered transducers. Various connectors & cables are available to interface a variety of transducers to a Bridge Amp, such as a Grass Adapter Cable for connecting to transducers with Grass connectors. The Bridge Amps are compatible with a range of ADInstruments and partnering products including:
- Blood pressure transducer
Used to measure arterial and venous blood pressure in animals. A BP (Blood Pressure) Amp is also available for invasive blood pressure measurements requiring full isolation. - Isotonic transducer
Suitable for investigating isotonic contractions of isolated organs and tissue, and measuring small displacements in physiological preparations. - Pressure Catheter + Catheter interface cable
Millar Mikro-Tip pressure catheters with pressure sensor(s) provides high-fidelity cardiovascular pressures (the heart and vascular system) at the source in small animals. - Physiological pressure transducer
A highly accurate and robust piezo-resistive transducer. - Force transducers
Ideal for isolated tissue studies with our range of tissue and organ baths - 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
