Low Cost Strain Gage Signal Conditioner
Calex Mfg. Co., Inc. of Concord, California, announces the 6202 Series of
strain gage signal conditioning modules. Designed for cost sensitive applications,
the 6202 provides precise excitation, amplification and filtering for any
strain gage based measurement or control system. The unit is housed in a shielded
1" x 2" case attached to a mounting flange. The 6202 housing is
ideal for mounting against a load cell, structural member or backplane.
The 6202 provides a fixed +10VDC excitation voltage with up to 30mA of current
making the unit capable of driving a variety of load cell/strain gages. The
6202 also provides a variety of fixed gain options to meet your application
requirements. Gain values range from 2 to 2965. The amplifier output is rated
at -3V to +15VDC. Extraneous noise is eliminated with the built-in 10Hz two
pole filter. The 6202 is powered by 24VDC with a tolerance of 18 to 26 Volts.
Current required for applications using a 350 Ohm bridge is 35mA.
The temperature coefficient of the 6202 amplifier is 0.005%/°C. Linearity
is ±0.01%. Common mode voltage is 0 to +5VDC with common mode rejection
of 100dB. Input noise from 0.1 to 10Hz is 0.3uV peak to peak.
