SU64517A1 - Valve photocell - Google Patents

Description

Valve photocells with high sensitivity and very npocToit design (manual, can be used as sensors for measuring instrumentation.

However, there are a number of reasons that prevent such use of photocells. HainpHMep, The sensitivity of a photocell depends on its temperature and service life. It is also impossible to have an illuminator that creates constant illumination for a long time.

In order to provide correction, it is known in photoelectric measuring devices that two photocells are imitated, one of which is (test and included in separate; electrically measuring device.

In the proposed valve photocell, this correction is provided in a simpler way. According to the invention, in order to eliminate the influence of fluctuations in the luminance of the illuminator and aging of the photocell, it is provided with an additional light-sensing layer, illuminated by that

the same illuminator and electromeasurements connected to the controls. so that the device is in order (for the first time it can be installed on the surface of the photocell by adjusting the luminance of the bodies).

The entity 13 acquisitions1 are illustrated in a drawing, in FIG. 1 which shows the photosensitive layer of the proposed photocell, on. 2 shows a screen and FIG. 3 - d program of the dependence of the photocell currents on the angle of the open screen.

Photosensitive layer photo, element. It has the same sensitivity over the entire surface, is divided into two parts - inside about 1, called the “scale,” and outwardly about 2 annular form, called a “10” corrector. Both parts 1 2 are illuminated by light.
