Series 3303/8 Inch AC Gaging LVDTs

The Series 330 3/8″ AC Gaging LVDTs provide precise linear displacement sensing in a compact, spring loaded package. Advanced coil windingues are employed to minimize package length and optimize overall performance. Spring forces have been carefully selected to insure the proper balance of mechanical frequency response and tip force. Available in strokes ranging from ± 0.005″ to ± 1.0″, these sensors are ideally suited to material thickness measurements, single or multi-point surface profiling, creep testing, or any other application re the use of a small, spring loaded LVDT. These transducers are also an excellent replacement for a standard dial indicator.

DC-DC OPERATION WITH OPTIonAL OSCILLATOR/DEMODULATOR

To facilitate prototyping, or in instances where the preference is a DC in – DC out system, any of the standard or High Temperature Series 330 can be used in conjunction with the Model 1000- 0014 Oscillator/Demodulator. Designed to work together, the DC system gives the same level of performance as provided by the AC LVDT alone. The high level DC output voltage can be directly interfaced with analog circuits as well as data ac cards, PLCs, or A/D converters. Provisions for customizing the Model 1000-0014 to provide zero offsets and nonstandard gains allow a simple and cost effective method of tailoring a system to meet individual customer re
