HIGHLY SENSITIVE AND HIGHLY ACCURATE LEVEL
PURPOSE:To provide a highly sensitive and accurate level which is small-sized, conveniently portable, and inexpensive, by providing a roll, a needle and the like on a casing and a rolling base panel. CONSTITUTION:A graduation is formed on a casing 1, and a needle 4 is attached to a roll 3 which is t...

| description | PURPOSE:To provide a highly sensitive and accurate level which is small-sized, conveniently portable, and inexpensive, by providing a roll, a needle and the like on a casing and a rolling base panel. CONSTITUTION:A graduation is formed on a casing 1, and a needle 4 is attached to a roll 3 which is then set on a base panel 8. If the base panel 8 is horizontal, the roll is stationary. When the base panel 8 is inclined, the roll 3 rolls under gravitational action. Accordingly, the needle 14 moves. At this time, a weight 11 is turned up in a direction reverse to the turning direction of the needle 4. Accordingly, the needle deflects in dependence upon a degree of accuracy, and the weight value of the weight 11 brakes the needle 4. When the balancing is obtained, the needle 4 comes to a stop. A sensitivity adjusting screw 12 is adapted to raise and lower the gravitational center. The lower the gravitational center, the worse the sensitivity. Further, a needle zero point adjusting screw 13 adjusts for a slight crosswise weight error, and the needle 14 is set so as come to a zero position. |
