Roulette operation is based on measuring the phase relationships between the emitted and reflected optical signals. It is a versatile device for making fast and accurate remote measurements of the distance from various fixed surfaces such as floors, ceilings, columns, as well as relatively hazardous and hard-to-reach objects such as elevator shafts or open staircases. A highly visible red laser dot for fast aiming allows one person to take safe measurements. The measurement result is displayed on the liquid crystal display in units of measurement. The tape uses laser radiation, which is safe for the user.
Economic attractiveness is determined by the need for high-precision non-contact distance meters for vehicles, geodetic and technological measurement systems, as well as in construction. The laser tape measure is capable of measuring distances indoors and outdoors, as well as calculating areas and volumes.
- range of measured distances, m 0.5 – 20.0;
- distance measurement error, mm – ± 5;
- measurement time in one step, ms – 0.15;
- supply voltage, V (3 batteries) – 4.5;
- dimensions, mm – 180x60x35;
- weight, g – 230.
The development is intended for contactless optical-electronic measurement of short distances; this process is characterized by a number of improved consumer properties; laser tape measures can replace mechanical tape measures.
TECHNICAL AND ECONOMIC EFFECT:
The price will be 250 – 300 UAH. in mass production, which is significantly lower than the price of professional laser meters 500 – 1500 $. This makes it attractive in the markets not only in Ukraine, but also in the CIS countries, Europe and other countries.
