Transducer Instruction Manual
Range:
Advance
Type:
ACDF
–
3
Revision:
V1.0
4.2
Low Output Signal With Maximum Tension
[1]
Check for correct wiring to the transducer.
[2]
Check cables and connectors for good continuity with an ohm meter, do
NOT
use a 'megger'.
[3]
The transducer may have too high a MWF, replace with a lower MWF transducer or increase the
web wrap angle.
[4]
The transducer excitation voltage may be too low.
4.3
Wrong Polarity of Output Signal
[1]
Check that the web path is correct.
[2]
The transducer may be incorrectly orientated, rotate 180
to correct this. If rotation is not possible,
interchange the transducer excitation supply or output signal leads at the indicator or controller
terminals.
4.4
Output Signal Not Linear, Zero Shifts During Operation
[1]
Check that there is no dirt or foreign matter interfering with the transducer mounting and that the
mounting hole diameter in the machine frame is correct.
[2]
Check that the four fixing bolts are secure.
[3]
Check that the bearing is completely free to rotate and align.
[4]
Check that one end of the tension sensing roller is free to float axially in the transducer bearing.
4.5
Transducer Strain Gauge Resistance
The transducer has four foil strain gauges in a Wheatstone bridge. The nominal resistance is 350 ohms.
