Series 3303/8 Inch AC Gaging LVDTs
The Series 330 3/8″ AC Gaging LVDTs provide precise lineardisplacement sensing in a compact, spring loaded package. Advancedcoil winding techniques are employed to minimize package length andoptimize overall performance. Spring forces have been carefullyselected to insure the proper balance of mechanical frequencyresponse and tip force. Available in strokes ranging from ± 0.005″to ± 1.0″, these sensors are ideally suited to material thicknessmeasurements, single or multi-point surface profiling, creeptesting, or any other application re the use of a small, springloaded LVDT. These transducers are also an excellent replacementfor a standard dial indicator.

To facilitate prototyping, or in instances where the preferenceis a DC in – DC out system, any of the standard or High TemperatureSeries 330 can be used in conjunction with the Model 1000- 0014Oscillator/Demodulator. Designed to work together, the DC systemgives the same level of performance as provided by the AC LVDTalone. The high level DC output voltage can be directly interfacedwith analog circuits as well as data ac cards, PLCs, or A/Dconverters. Provisions for customizing the Model 1000-0014 toprovide zero offsets and nonstandard gains allow a simple and costeffective method of tailoring a system to meet individual customerre
