We recommend this connection technique for very small measurement ranges, in particularly
disturbed environments 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.
