¼, ½, and Full Bridge Strain Gage Signal Conditioner



Calex Mfg. Co., Inc. of Concord California announces the availability of the Model 163MK Strain Gage Signal Conditioner. The 163MK is designed to accomodate 1/4, 1/2 and full bridge strain gage applications. The unit offers 1/4 bridge completion and calibration for applications such as materials and structural testing. The 163MK has two built-in precision 1/2 bridge completion resistors for 1/2 bridge applications. The 163MK 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"W. All connections and trim pots are easily accessible. The unit is powered by ±15VDC. The gain of the 163MK amplifier can be set as high as 5000 making the unit ideal for very low level signals. The amplifier output is ±10V making the unit 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. The 163MK is backed by Calex's five year warranty.

Pricing for the Model 163MK is $232.40/ea (100). Units are available from stock to 6 weeks. For more information, contact Calex Mfg. Co., Inc. via phone 925-687-4411 / 800-542-3355 or fax 925-687-3333. For a complete data sheet on the Model 163MK go to calex.com/pdf/163MK.pdf or email sales@calex.com. The Calex corporate address is 2401 Stanwell Drive, Concord, California 94520 USA. Calex has manufacturing facilities in both Concord California and Tijuana Mexico.
