LPM/LPX 2000 LPM/LPX 2000 Series High Accuracy, Low Absolute Pressure Sensors ! Accuracy: <0.2% FS BSL ! Ranges: 0 to 0.03 through 0-150 psia ! Lowest Measurement 0.03 x 10-4 psia ! Outputs: 2-wire 4-20 mA, 3-wire 0-5Vdc, 0-10 Vdc ! All media compatible with 316L SS, Inconel X750, Inconel 600 The LPM/LPX 2000 Series absolute pressure transducers are suitable for high-precision applications such as Secondary Calibration Standards, Chemical Reactor Vessels, Leak Detectors, or anywhere critical measurements are required. The high overpressure, chemical compatibility and excellent long-term stability, assure the highest reliability available in the industry. The measurement cell is an Inconel X750 capsule, vacuum sealed to 1 X 10-6 Torr. The eddy current sensor, formed by two coils, perfectly sealed from the measurand by the force-collection diaphragm, measures the displacement of the capsule without any mechanical contact. When the diaphragm moves under the effect of applied pressure, eddy current losses generated in the target results in a variation in inductance in the coil. This variation is measured relative to the reference inductance of a second coil, which after conditioning, presents a standardized signal directly proportional to pressure. This measurement system allows the use of metallic capsules over very low displacements, thus working well within elasticity and fatigue limits. !"
