For amplifiers MX840B, MX440A and MX410B, we re
commend this connection technique for very small meas
urement ranges, particularly in environments subject to
interference and when using long cables.
This applies for all bridge connections.
With cable lengths >50 m, a resistor with half the value of
the bridge resistance (RB/2) must be connected in each
sense lead of the transducer.
