(2.08) (4000)
so 10 V output from the RX10K indicates 4,901 ft-lb of torque or
490.1 ft-lb/volt.
Step 2: Scale the Full Scale Output
If desired, the Full Scale voltage output of the TX10K can be
scaled so that it corresponds to a convenient torque value, e.g.
100 ft-lb/volt. As stated earlier, the System Gain can be adjusted
from ¼ to 4 times the Transmitter Gain. The equation below
defines the Scale Factor (Z):
