Liquid Manometer

An automatic liquid manometer which operates on the basis of a position-detecting system is described. A slanting laser beam is directed to the meniscus of liquid in a glass tube manometer without a float and is reflected by the meniscus. The reflected spotlight is focused on a position-sensitive detector (PSD) through a lens. The application of external pressure to the manometer causes the position of the meniscus to change, and the pressure can be gotten indirectly by this position. The relationship of the output of PSD to the displacement of meniscus was investigated, and the fuzzy control rules were determined to make the meniscus back to its original position fast and stable. The system has been tested with good results.

A state-of-art semiconductor technology-based position sensitive area detector, namely D/teX-25, has recently been developed for high-speed and high-sensitivity X-ray diffraction (XRD) analysis of materials. X-ray powder diffraction intensities obtained by a D/teX-25 detector were found to over 50 times higher than those by a conventional scintillation counter. A D/teX-25 detector mounted on a conventional 2 kW XRD system has been used to collect ultrafast XRD data with scanning speeds up to 160°2θ per minute. Ultrahigh-speed XRD is particularly useful for time-resolved dynamical and in-situ studies. A D/teX-25 detector was successfully used on a Rigaku XRD differential scanning calorimetry (DSC) system for simultaneous measurements of XRD and DSC data under controlled temperature and humidity conditions. This has made possible the study of complex and rapid phase transformations of pharmaceutical terfenadine. The D/teX-25 area detector has also been used for recording two-dimensional XRD patterns showing the particle-size effects on α-quartz powder intensities and to obtain digital X-ray topographic images of a complex dislocation network in a Si wafer.
