These
are the standard DC-EXCITED LONG-STROKE LVDT
models with CAPTIVE ARMATURE. Operating
from a simple unregulated power supply of +20 to +40 VDC (or dual ±10 to
±20 VDC), each LVDT generates two standard ±5 VDC antiphase
output signals. These two outputs can be used individually, or they can be combined to yield a
high-level ±10 VDC "differential output signal." For
low-output (±2 V) versions, see the DC
"LC2" LVDT Series (2-wire 4-20 mA output is also
available as an option—contact
the factory for details).
Each
model includes high-quality electronics for energization and signal
conditioning. Encapsulated, integrated electronics are suitable for
operation in harsh industrial environments. All models are fitted
with 2 meters (6.6 ft.) of shielded cable. For hermetically sealed
versions, see the DC "LCM" LVDT Series.
General Specifications are
given below.
