High precision displacement sensors for extreme environments

KMM Precision Measuring‘s high precision displacement sensors are for extreme environments such as power generation, including nuclear and aerospace propulsion, rocket engine turbo pumps, materials research and development, with operating temperatures from -320°F to +1000°F (+1200°F short term) at pressures up to 5000psi. 

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 stand up to high temperature, high pressure, vibration and environmental contaminants. 

Three displacement measuring systems are available, all able to operate at high temperatures. KD-1925 withstands pressures up to 5000 psi; and KD-1950 and KD-1975 withstands pressure up to 3500 psi.

The sensors use the versatile KDM-8206 signal conditioning electronics. Single channel systems are available in the NEMA-enclosures or bench-top/ rack-mountable Eurocards. The NEMA enclosure houses an internal power supply, digital panel meter and window kit. Up to twelve measuring channels are available in the rack-mountable KDM-8206.
