Special particularized sensitive piezoresonanse pressure transducers

Results of working out of particularized sensitive quartz piezoresonanse pressure transducers of 0,08 and 0,02 classes with digital outpoot have been presented at Radar mms JSC.
For the purpose of providing opportunity for the transducers to be calibrated up to 60 MPascal, metrological laboratory with known good pressure devices of 0,01 and 0,005 classes from measurable quantity was organized.
Technology of placing of native barsensitive and temperature sensors as well as particularized microcircuit into the frame has been assimilated, hydro mechanical stableness is guaranteed.
Method of pictorial evaluating of accuracy rating of sensors in working temperature range with help of pie chart of sensors errors in accordance with modulus of their value and diagram of temperature hysteresis has been worked out.
For verification of piezoresonanse pressure transducers at the objects and submersible crafts plug-in modules of calibrators of 0,02 class have been worked out.

Keywords: particularized sensitive quartz piezoresonanse pressure transducers, pressure transducers.

Development of a fiber optic probe refractometer to measure the concentration of solids sugar solutions

Explain the rationale for the selection of the wavelength of the fiber-optic Refractometer. Developed and described the optical scheme and the design of fiber-optic refractometer FOR-411-VIS/2.1.
Research was carried out for measuring the content of dry substances of sucrose from 1 up to 70 % on refractometers R, URL, URF, and FOR. It is established, that testimony obtained on different devices close. Developed by a Refractometer FOR works on the wavelength of 589,3 nm and to improve the accuracy of developed tip with a larger refractive index of the optical element probe to 2,1745, as well as the increased effective diameter of the light beam up to 7.5 mm.
Made the model of the device and it was tested in laboratory conditions FORC-Photonics and GNU VNII of starch products.

Keywords: refractometer, refractive index, fiber optics, fiber-optical system, glucose, fructose, sucrose, wavelength.
