LVDT sensor with special flange and increased impedance for numerous industrial applications in production, inspection, quality assurance, testing and laboratory, especially for installation in test cylinders of dynamic testing machines. The LVDT sensor with a Case diameter of 12mm has a coil unit calibrated to 80mV/V with fully symmetrical coil construction according to the LVIT differential choke principle / half-bridge circuit. The proven design guarantees high temperature stability with very low temperature drift. Variants with different Carrier frequencies and increased temperature and dynamic ranges are available.
Special versions with modified flange and connection dimensions according to customer requirements are possible.
