These
high-performance transducers are the standard AC-EXCITED LONG-STROKE LVDT
models with CAPTIVE ARMATURE. They
are ideal for harsh applications under conditions of high ambient
temperature and/or vibration.
Each
model requires separate signal
conditioning, and will deliver its best performance when energized
between 0.5 and 7 VAC (RMS) at 5 kHz, using a high-quality carrier
amplifier.
Compact
size allows use where physical space is limited. All models are
fitted with 2 meters (6.6 ft.) of shielded cable. For hermetically
sealed versions, see the AC "LCM"
LVDT Series.
General Specifications are
given below.
