AC-Operated, Long-Stroke
Spring-Extended Armature

NOTE: All of the AC "LE" Series LVDT's have retained their "classic" Daytronic model numbers.

These high-performance transducers are the standard AC-EXCITED LONG-STROKE LVDT models with SPRING-EXTENDED 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 "LEM" LVDT Series.

General Specifications are given below.
