KMM Precision Measuring highlights the availability of high-precision displacement sensors for extreme environments, including power generation (nuclear and aerospace propulsion), rocket engine turbo pumps, and materials research and development, with operating temperatures from -320°F to +1000°F (+1200°F short-term) at pressures up to 5000 psi.
Originally designed for NASA and the nuclear power industry, these sensors provide non-contacting measurement of conductive surface motion with unsurpassed accuracy and reliability under the most hostile operating conditions.
KMM’s sensors are made with hermetically sealed, laser-welded Inconel housings and use metal-jacketed, mineral-insulated cable to withstand high temperatures, high pressures, vibration, and environmental contaminants.
Three displacement-measuring systems are available, all capable of operating at high temperatures. KD-1925 withstands pressures up to 5000 psi, and KD-1950 and KD-1975 withstand pressures up to 3500 psi.
The sensors use the versatile KDM-8206 signal conditioning electronics. Single-channel systems are available in NEMA enclosures or benchtop/rack-mountable Eurocards. The NEMA enclosure houses an internal power supply, a digital panel meter, and a window kit. Up to twelve measuring channels are available in the rack-mountable KDM-8206.
