3/8 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 winding techniques 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 requiring the use of a small, spring loaded LVDT. These transducers are also an excellent replacement for a standard dial indicator. KEY FEATURES Ranges from ±0.005” to ±1.0” Self-Lubricating Bearing SPECIFICATIONS MODEL LINEAR RANGE OUTPUT MONOTONIC OVER ENTIRE MECHANICAL TRAVEL TEMPERATURE RANGE TEMP.

RESPONSE ACCESSORIES PART NUMBER DESCRIPTION A002-0041 Adapter for alternate contact tips: 5-60 Thread to 4-48 UNF-2B Thread Contact Tip, .30″ Spherical O.D.; 5-60 Internal Threads. (Included with transducer) 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,...

HIGH TEMPERATURE VERSION: -65°F to +400°F (-55°C to +204°C) The High Temperature version of the Series 330 is identical to the standard version except for the following: PHASE ANGLE Degrees INPUT IMPEDANCE Ohms INPUT OUTPUT RESISTANCE RESISTANCE Ohms Ohms Units terminate in six #30 AWG Teflon insulated leads (3 ft. long); Some materials such as the epoxy, solder, and magnet wire have been replaced by their high temperature equivalents; Electrical characteristics of certain units have been changed as described in the accompanying table. Note: all electrical and physical specifications are...
