DISTANCE MEASURING SYSTEM USING LASER TECHNOLOGY FOR THE DETERMINATION OF LEVELS

摘要

The system comprises a sensor head (1), which may be integrated in various configurations of a system and which includes a laser emitter (10) and an optical receiver (13) which are used to obtain a distance measurement, preferably corresponding to the level of a product (3) inside a tank (4). The head (1) also includes an electronic assembly (12) which provides a data signal related to said distance measurement, to the temperature sensed by external sensors and to the pressure detected by a pressure sensor (15) which optionally integrates the head (1). The sensor head (1) is fixed, when necessary, by means of a mechanical levelling system to the tank (4) and by means of a plate (6) which has a manual gauge plug (8) and a hatch (7) to clean the head (1).
