APPENDIX A

GENERAL TRANSDUCER CONNECTIONS:   AX, AC, MD, SA, SM Series, & MACH 1

Connections to connector 2 should be made as indicated:

Yellow wire on LVDT’s:

a) 

Normally left unconnected and insulated.

b) 

On some transducers a resistor must be connected from yellow to green or white as 

 

instructed on  transducer calibration sheet.

c) 

Do not extend beyond standard cable length fitted to transducer.

Where screen is used, connect to case of plug. Ensure that elsewhere the screen is isolated 

electrically.

Cable colours are as fitted to Solartron transducers.

Increase of element impedance marked P gives a positive going voltage output.

  

Note:  The black lead should only be connected if the transducer case is to be grounded.
