Beschreibung: Bridge Amplifier and Meter

The BAM-1 Bridge Amplifier and Meter is a battery- operated instrument used primarily to measure the -output of resistance-type strain gages or transducers. Static outputs can be read directly on the self-contained deflection meter or an external recorder; dynamic outputs up to 20 kHz can be read on an Oscilloscope. . Briefly, the BAM-1 consists of: a) A battery to supply bridge excitation up to 12 Vdc; b) Bridge completion and circuits to achieve initial bridge balance; c) Shunt-calibration circuits; d) A fixed-gain dc differential Amplifier (with battery power); and e) A linear 4½" center-zero readout meter. 1.2 The principle features of the BAM-1 include: ... Operation by self-contained batteries (115 and 230 Vac Power Packs optional). ... Ultra-stable dc Amplifier with a gain of 250, flat up to 20 kHz (100 kHz in Model BAM-1B). ... Adjustable system gain from ± 100 to 15,000 µe full scale (one active 120Ω gage). ... Built-in shunt calibration from 20 to 20,000µe in 10 steps (one active gage). ... Amplifier can be used independently for thermo couples, etc.
