Brief introduction: LLE-2DC-750 series pressure sensor is the concentrated embodiment of Kulite's most advanced pressure sensor technology and technology, the extremely light weight and flat shape make it directly pasted on the test body that cannot be installed and used by other pressure sensors; It is the best choice for wind tunnel, flight testing, nozzle (vector, etc.) and airframe pressure testing. The output is digitally compensated with high precision, so that the product has a comprehensive accuracy of not less than 0.25% over a fairly wide temperature range. ●Leadless patented technology; ●Wind tunnel and flight tested; ● For nozzle and fuselage pressure; ● 5VDC output; ●With moisture-proof protection;
