330

产品简介:

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.
