<p>The solution is characterized by the first optical axis (6) are sequentially positioned light source (1), collimator (2) and input box (31) hydro levelling cells (3), the second optical axis (7) perpendicular to the first optical axis (6) are placed sequentially output window (32) hydro levelling cells (3), an imaging system (4) and line CCD sensor (5), while the level of (8) hydrostatic fluid (9) is broken in the light beam in space between the entrance window (31) and output window (32) hydro levelling cells (3), the body which is located thermometric IUD (35), while the light source (1), thermometers IUD (35) and line CCD sensor (5) are electrically associated with control and signal circuit (10), which through the abutting circuit (11) connected to a personal computer (12).</p> |
