INTRODUCTION

Where damage to a sensor or cable is suspected this guide illustrates the way in which simple

resistance checks can be taken to identify the possible cause of the problem.

Resistance checks can be made with most types of multi-meter which are readily available in the

market.

RESISTANCE OF THE COILS

STEP 1

Set the range to 200Ω or Ω if using a multi-meter which has automatic ranging.

STEP 2

Connect the VW+ (red) conductor to the red lead on the multi-meter and the

VW- (black) to the black lead on the multi-meter.

The correct readings should be as follows ±10%

Pressure Transducer ~ 160Ω

Strain gauge

Co-axial coil

IF THE VALUES ARE OUT OF THESE RANGES THEN THERE IS A FAULT IN THE COILS

IF THE VALUES ARE 50% THEN THERE IS A PROBLEM WITH ONE OF THE COILS

~ 180Ω

~ 50Ω
