Description

Известные устройства дл  тарировани  датчиков давлени  гидрометеорологических ириборов, содержащие U-образный ртутный манометр , одно из колен которого сообщено с атмосферой, а другое - с камерой дл  установки повер емых датчиков, не позвол ют автоматизировать процесс тарировани , в св зи с чем нри тарировке датчиков возможно по вление субъективных ошибок и наличие больших погрешностей .The known devices for calibrating pressure sensors of hydrometeorological instruments, containing a U-shaped mercury manometer, one of whose knees communicates with the atmosphere and the other with a camera for installing adjustable sensors, do not allow to automate the process of calibration, due to which calibration of sensors possible subjective errors and the presence of large errors.

В предлагаемом устройстве на поверхности ртути в колене манометра , сообщенном с атмосферой, установлен поплавок со стержнем, ча котором закреплена выполненна  фотографическим путем программа тарировани  дл  считывани . Лучи света, проход  через программу тарировани , попадают на фотоэлектрический преобразователь, подключенный к блоку управлени  работой самописца давлени , электромоторного крана и дросселей вакуумного насоса. Это отличие позвол ет автоматизировать операции процесса тарировани  датчиков давлени .In the proposed device, a float with a rod is mounted on the surface of the mercury in the knee of the pressure gauge in communication with the atmosphere, and the float is fixed with a photographic calibration program for reading. Rays of light passing through the calibration program fall on a photoelectric converter connected to the control unit for the operation of the pressure recorder, the electromotor valve and the chokes of the vacuum pump. This difference automates the process of calibrating pressure sensors.

На чертеже приведена принципиальна  схема предложенного устройства .The drawing shows a schematic diagram of the proposed device.

Устройство содержит U-образный манометр /, одно колено которого сообщаетс  с камерой 2, а другое - с атмосферой. В кам.еру 2 помещаетс  испытуемый датчик. На поверхности ртути в колене манометра, сообщенном с атмосферой, помещен поплавок 3 с рейкой 4, в прорези которой вклеиваютс  программы тарировани , полученные фотографи-ческим путем. Программа представл ет собой контрастные полоски различной ширины, расноложенные на определенном рассто нии друг от друга.The device comprises a U-shaped pressure gauge /, one knee of which communicates with chamber 2 and the other with atmosphere. A test sensor is placed in cam 2. On the surface of the mercury in the knee of the manometer, communicated with the atmosphere, is placed the float 3 with the rail 4, in the slots of which are pasted the calibration programs obtained by photographic means. The program consists of contrasting stripes of various widths, spaced at a certain distance from each other.

С одной стороны рейки расположен осветитель 5 с оптической линзой 6, а с другой стороны - фотоэлектрический преобразователь 7, освещенность которого мен етс  при перемещени х рейки с программой.On one side of the rail there is an illuminator 5 with an optical lens 6, and on the other side a photoelectric converter 7, the illumination of which changes as the rail moves with the program.
