7612 IEPE Voltage Signal Conditioning Amplifier - 1

• Dual channel per module • Differential signal amplifier with high bandwidth • Fully calibrated gain from 1to 1,000 by 1 121 b.. • Accepts quartz type sensors. • Selectable step excitation : 2 to 20mA • Plug-in amplifier • Front-panel monitors : transducer bias voltage • Front-panel monitors : short or open circuit in • Quartz Accelerometer • Pressure transducer • Force transducer • Strain transducer 7612 Voltage signal conditioning system is designed with and incorporates all the features necessary for dynamic precise conditioning of quartz transducer inputs in the most severe operating environments. 7612 can simultaneously signal condition and amplifies low-level signals to high-level outputs on multiple channels. It is also capable of dynamically recording and displaying on external devices. Use for powering ADI low impedance quartz transducers and amplifying the signal in multi- channel systems for laboratory, field or factory applications. These dual channel amplifying power units provide adjustable 2 to 20 mA constant current excitation to the transducer and gain adjustment from 0 to 1,000 by 1 / 2 / 5 step gain switch. High-level excitation current is particularly useful when driving long cables at high frequencies in field or factory applications. Buffer amplifier output maintains the time constant independent of the load impedance. The self-test circuit monitors the transducer bias voltage and indicates normal or faulty operations such as a short or open circuit in the cable. Microdot SMA input and BNC output connectors are isolated from chassis ground.
