Installation Guide - Position Transducers

V across the application range. Series 6 position transducers are factory preset to 0-5 V or 5-0 V across the design 
range. For example, if the transducer has a design range of 85 inches (2159 mm) but only 75 inches (1905 mm) are 
being utilized during measurements, the transducer can be calibrated using the zero and span controls to reflect ±5 
V across 75 inches (1905 mm). This flexibility is beneficial but there are limitations as ilustrated by using the 
Voltage Conditioner Zero and Span Calculator:

10. Connecting The Displacement Cable

Standard position transducers are provided with a swivel and pull ring for 
attachment to the application. An uncrimped loop sleeve and copper sleeve 
are provided for securing the cable into a loop. This arrangement allows 
you to place the swivel or pull ring on the displacement cable precisely 
where you need it.

If you need to cut uncoated displacement cable, you should anneal the 
cable with a flame (a candle, lighter, or match will work fine) at the cutting 
point to ensure the cable does not fray after cutting. Heat the cable until it 
glows red and then cut the cable in the area that was heated. See Figures 6 
and 7.

Crimping the Ball-End Plug Using the Crimp Tool (provided in the 160001-01 installation kit)

1.  Grip and center the ball-end plug lengthwise in the crimp tool using 

the bottom hole (hole closest to the crimp tool handles; see Figure 8.

2.  Thread displacement cable through ball-end plug until desired 

crimping location is reached.

3.  Squeeze crimp tool firmly until the tool jaws fully mate. Rotate the 

ball-end plug 90° and squeeze crimp tool firmly. Minor crimp 
imperfections are to be expected.

4.  Pull on the displacement cable while holding the ball-end plug and 

ensure that the crimped ball-end plug is secure.
