Ectron 350 Series Environmental Amplifier/Signal Conditioner
The Ectron 350 Series Amplifier/Signal Conditioners are small environmental differential dc amplifiers with built-in variable voltage bridge excitation supply. Three models comprise the 350 Series, differing only in physical size and mounting configuration. With an input impedance of 20 Megohm and bandwidth of 20 kHz, they are designed for use with a wide variety of external transducers including piezo-resistive type strain gages. The dense packaging, encapsulated construction and advanced design result in a finished product which can produce highly accurate data under the most severe conditions. All models are complete with a full set of front panel operating controls including selectable gain steps of 1, 2, 5, 10, 20, 50, 100, 200, 500 and 1000 with a X2.5 vernier gain which may be switched in or out. Also included are output zero, bridge balance and adjustable excitation voltage controls. Protection against electromagnetic interference (EMI) and radio frequency interference (RFI) is obtained through the use of a steel case and filters on all input, output, excitation and power leads.
