Series 210-220

Long Stroke AC LVDTs

The Series 210-220 AC LVDTs offer precision linear displacement measurements for applications with strokes from 0.5 to 60 inches. The transducers have been designed with an extremely low temperature coefficient, and non-linearity of less than ±0.25% F.S. Variable pitch secondary windings are incorporated into the design with computer controlled winding machines to minimize package length to stroke ratio, and assure a uniform product.

CORE EXTENSION RODS (Sold Separately)

The recommended core extension rods are made of nonmagnetic stainless steel and are sized to allow the transducers to operate over their full range. Extension rods from models with longer strokes may be used to facilitate installation. Using extension rods shorter than recommended may reduce the LVDT’s usable measurement range.trans-2016-210-220-core-rods

DC-DC OPERATION WITH OPTIONAL OSCILLATOR/DEMODULATOR

To facilitate prototyping, or in instances where a DC in – DC out system is preferred, any of the standard, high temperature or vented Series 210-220 can be used in conjunction with the Series 1000 Oscillator/Demodulator. The DC system provides the same level of performance as a stand-alone AC LVDT. The high level DC output voltage can be directly interfaced with analog circuits as well as data acquisition cards, PLCs, or A/D converters. Each Oscillator/Demodulator can be customized to provide a zero-offset and nonstandard gain, meeting specific user requirements. Detailed connection information can be found in the Sales portion of the datasheet.

SERIES 210-220 MODIFIED FOR USE IN HIGH PRESSURE ENVIRONMENTS

The high pressure version of the Series 210-220 is suitable for operation in nonconductive and noncorrosive fluids or gasses at pressures up to 5000 P.S.I. The vented housing eliminates pressure differentials between the environment and the transducer’s interior, allowing rapid and extrerme pressure changes without damage or degradation in performance.

SERIES 210-220 MODIFIED FOR USE IN HIGH TEMPERATURE ENVIRONMENTS

The high temperature version of the Series 210-220 has been designed to operate in temperatures from -67°F to +400°F. The LVDTs are identical electrically and mechanically to the standard Series 210-220 transducers, providing the same high level of performance and reliability. To achieve the elevated operating temperature, materials such as the epoxy, solder, and magnet wire have been replaced by their high temperature equivalents.

NOTE: All electrical and physical specifications are the same as the standard Series 210-220 LVDTs.
