Transducer Conditioning Amplifier Ectron Model 563H provides excitation, balance, calibration and amplification for once, two or four-arm bridge-type transducers and other low and high-level signal sources.

Constant-voltage bridge excitation is front-panel variable from 0.1 to 15 volts with front-panel monitor jacks. A shunt-CAL switch, bridge balance, excitation disconnect and LED display of balance or offset are also provided.

Gain is front-panel selectable from 0.01 to 25 or 1 to 2,500 in 10 calibrated gain steps in a 1, 2, 5 sequence plus a x2.5 gain vernier. Selection of gain range is by a board-mounted 100:1 input-divider switch.

Front-panel controls include both RTI and RTO zero with the RTO-zero range board-mounted switch selectable at ±10V, ±1V or ±100mV. Amplifier-output monitor jacks are also provided.

Transducer Conditioning Amplifier Ectron Model 563H bandwidth is DC to 200 kHz and optional two-pole Bessel filters with front-panel-selectable frequency cutoffs of 10 Hz, 100 Hz, 1 kHz, 10 kHz and a wideband position permit user selection of lower bandwidth.

Features:

• Bandwidth DC to 200 kHz
• Selectable 5 step filter
• Variable excitation - 0.1 to 15 Volts
• Null indicator LEDs
• 1/4, 1/2 and full bridge completion
• Bridge balance and shunt cal
• Gains from 0.01 to 2,500
