The Signal Conditioner has two built-in precision 1/2 bridge completion resistors for 1/2 bridge applications. It can also handle full bridge applications such as load cells for hopper and tank weighing applications.
In addition to 1/4 and 1/2 bridge completion, the unit has a high gain differential amplifier, two pole Butterworth filter, and built-in excitation supply capable of providing up to 120mA of excitation current.
The 163MK is relatively compact, measuring 4.5 x 2.5 x 0.5-in. (114 x 63.5 x 12.7mm). All connections and trim pots are easily accessible. The unit is powered by ±15VDC. The amplifier's gain can be set as high as 5000 making it suitable for very low level signals. Its output is ±10V, making it compatible with virtually all data acquisition and control systems.
The output filter cutoff frequency can be set at 10Hz, 100Hz or 1kHz with an on-board DIP switch. The filter can also be set to any frequency from 10Hz to 10kHz through the use of user supplied resistors and capacitors. Output offset and bridge balance pots are available for tare and system adjustments. The amplifier also has an input offset for nulling the instrumentation amplifier.
