The KD-1925 is a high-temperature displacement sensor designed for noncontacting measurement of conductive surface motion in extreme environments, including high pressure, radiation, and thermal extremes. It features a hermetically sealed, laser-welded Inconel 718 housing and operates from -320°F to +1000°F, with a 0.050 inch measuring range and output of 0-2 Vdc nominal (50 mV/mil). The sensor withstands pressures up to 5000 psi, maintains nonlinearity within ±1.5% FSO at calibrated temperature, and has a frequency response of 0-10 kHz (3 dB), extendable to 30 kHz on request. Its dual-coil design compensates for thermal drift, with zero and sensitivity shifts of 0.03%/°F FSO. The sensor uses a mineral-insulated Inconel 600 cable and mounts via 5/16-24 thread or flange. It requires KDM-8200 electronics for signal conditioning.
