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.
