2.4 Primary Frequency
Primary amplitude is not adjustable. The LVC
uses ratiometric techniques and is insensitive
to primary amplitude. Maximum secondary
transducer amplitudes must be observed.
Refer to section 5.1.
The LVC has two input load ranges. 100 k Ω is often used for
LVDT transducers while 2 k
Ω
is often used for Half Bridge
transducers. If loads of less than 100 k
Ω
are required, an
external resistor may be wired across the SEC1 and SEC2
terminals. Most transducers perform well into 100 k Ω . See
specifi cation section 7.2 for further details.
100 k Ω - link PARKED
2 k
Ω
- link ON
2.5 Transducer Input Load
The LVC has selectable bandwidth (BW). The bandwidth
setting is independent of other LVC settings. Where
possible, the lowest bandwidth setting should be used to
minimize output noise.
250 Hz - Link ON
500 Hz - Link PARKED
Note: Total system bandwidth is dependent on sensor
type and application
