Signal Conditioners
Load Cells are used to convert the strain on the metal to a
variable resistance. The bridge configuration of the strain
gauges, allows the load cell to output a low level voltage change
based on the input voltage (maintained at a constant and stable
level) and the amount of strain or load placed on the load cell.
At full load the nominal voltage output with a 10 volt dc input
is 20 millivolts to 30 millivolts. This signal can be conditioned
by our signal conditioners to provide
0 to 10 volts, or 4 to 20 milliamps, or RS232 with a 0 to 30,000
digital output.
Model S-0-10 load cell signal
conditioner with 0 to 10 volt dc output.
Cell excitation voltage is 12 volts @ 500ma.
Span calibration by multi-turn pot.
Span range capable for a minimum 1.5 mv. per volt input (18
millivolts) for 10 volts.
Zero range is 2.5 millivolts plus and minus.
Model S-4-20 load cell signal
conditioner with 4 to 20 ma. output.
This unit will supply excitation voltage to power single or multiple load cell
systems. The
signal from the loadcell(s) is converted to a 4to20ma. analog current level
representing the load
being applied to the cell.
The unit runs on standard 120 vac power or can be ordered with 220 vac or 12 vdc
input power.
Cell excitation voltage is 12 volts @ 500ma.
Span calibration by multi-turn pot.
Span range capable for a minimum 1.5 mv. per volt input (18
millivolts) for 20 ma.
Zero range to set 4ma. is 2.5 millivolts plus and minus.
