optical transducer amp The SI-BAM21-LCB is designed specifically for use with the SI Heidelberg KG series force transducers. Also available in a single standalone enclosure (see page 6), either version provides an incredibly quiet, linear and stable transducer signal to your data recording system. Features l rapid Auto zeroing function with fine offset adjustment l Offset indicator LeD’s l multiple gain ranges with adjustable fine tuning for precise calibration l Digital interface for optional Anti-Oscillation module for use in isotonic studies Bridge amplifier The SI-BRIDGE80 module is designed for use with standard bridge type transducers to measure pressure, force, or displacement. Features l multiple gain ranges from 1X to 1000X plus an adjustable gain option l Defeatable offset adjustment control l Low pass filter down to 30 Hz l Operates in differential or single ended configuration AMPLIFIERS, ELECTROMETERS Si-BaM21-lCB Optical Transducer Amplifier Si-BriDGE80 Bridge Amplifier Si-BriDGE80 SpECiFiCationS Si-BaM21-lCB SpECiFiCationS Input Configuration Gain Input Offset Adjustment Output Impedance power Output range Current to voltage converter 1×, 2×, 5×, 10× Optional factory setting: 10×, 20×, 50×, 100× ± 2.0 VDC 470 Ω 12 VDC provided by chassis ± 10 VDC Low pass Filter Band (KHz) Input Impedance power Amplification Input Leakage Current Voltage Offset Adjustment Amplifier Output Voltage excitation Voltage equivalent Noise Signal Input > 1012 Ohms 12 VDC provided by chassis 1, 10, 50, 100, 500, 1000 and Adjustable 0.1 pA at 25 °C ± 50 mV (low); ± 100 mV (high) ± 4.4 V (10 mA max.) 10 V (± 5.0V) 100 mA max < 0.4 µV rmS (2 µV p-p) 0.1–10 Hz Gain >10 < 3 µV rmS (15 µV p-p) 0.1–100 Hz Gain >10 0.03, 0.1, 0.3, 1, 5, 10, Wide Band r-C Butterworth 6 dB / Octave World Precision Instruments UK: Tel: +44 (0)1462 424700 • wpiuk@wpi-europe.com www.wpiinc.com Germany: Tel: +49 (0)30-6188845 • wpide@wpi-europe.com US: Tel: 941-371-1003 • sales@wpiinc.com 83
