Series 230

0.375” O.D. AC LVDTs

The Series 230 3/8” AC LVDTs offer precision linear displacement measurements for applications with strokes from 0.01 to 2.0 inches. The transducers have been designed with an extremely low temperature coefficient, and non-linearity of less than ± 0.25% F.S. The small size of these transducers make them ideal for weight critical applications and placement in tight spaces. The core is light enough to be used in systems with low driving forces or high accelerations without adversely affecting the system performance.
