TruAccuracy™ means the Ashcroft CXLdp has ±0.25% of span accuracy out of the box. Zero and span setting errors are already included in the ±0.25% of span accuracy spec. The CXLdp is ready to be installed with no additional calibration adjustments required. A unit from another manufacturer advertised as ±0.25% best fit straight line may actually be a ±1.25% to ±2.25% device. Using best fit straight line method, the accuracy spec does not include zero and span setting errors, which can be as much as ±1.00% each. What Does It Mean? Featuring a highly reliable variable capacitance sensor using the patented Ashcroft® Si-Glas™ sensor. This ultra-thin single crystal diaphragm provides inherent sensor repeatability and stability.SENSOR CROSS SECTION Ashcroft® Si-Glas™ Sensor Technology Sensor Cross Section The silicon diaphragm sensor has no glues or other organics to contribute to drift or mechanical degradation over time.
