LASER LEVELLER

Other Chapters

  • Q1: Define Laser Level?
    Ans: A laser level is a control tool consisting of a rotating laser beam projector that can be affixed to a tripod. It is used in surveying and construction for accurate measurements.
  • Q2: Define self-leveling.
    Ans: Self-leveling is an automatic adjustment mechanism in laser levels that ensures accuracy by maintaining a level line of sight even if the instrument is slightly tilted.
  • Q3: Define IP rating.
    Ans: IP (Ingress Protection) rating indicates the level of protection a device has against dust and water.
  • Q4: What is Amp-Hour Rating?
    Ans: Amp-hour rating refers to the battery capacity, indicating how long a rechargeable battery will last before requiring a recharge.
  • Q5: What is Vast Operating Temperature?
    Ans: Vast operating temperature refers to the temperature range within which the laser level can function accurately.
  • Q6: Name parts of Laser Level?
    Ans: The main parts of a laser level are:
    • ➔ Laser transmitter
    • ➔ Laser receiver
    • ➔ Control box
  • Q7: What are types of Laser level w.r.t Laser?
    Ans: Types include:
    • ➔ Dot Laser Level
    • ➔ Horizontal Laser Level
    • ➔ Dual-Beam Laser Level
    • ➔ Line Laser Level
    • ➔ Rotary Laser Level
  • Q8: What are types of Laser level w.r.t Its Functions/features?
    Ans: Types include:
    • ➔ Tower-mounted laser level
    • ➔ Manual-Leveling Lasers
    • ➔ Automatic Laser Levels
  • Q9: Describe accuracy of laser level.
    Ans: Good laser levels are accurate within 1/16 of an inch per 100 feet.
  • Q10: Define Refraction?
    Ans: Refraction is the phenomenon where light changes direction when it passes from one medium to another.
  • Q11: State benefits of laser level?
    Ans: Laser levels help reduce labor, increase work speed, and improve measurement accuracy.
  • Q12: State Working of Laser level.
    Ans: Laser levels work by generating a laser beam inside a protective housing, which is then projected onto a surface for reference.
  • Q13: What is difference between rotary and line laser level?
    Ans: A rotary laser level projects a 360-degree beam, while a line laser level projects a straight line or crosshair.
  • Q14: What is laser beam orientation?
    Ans: Laser beam orientation determines whether the laser projects in a horizontal, vertical, or 360-degree plane.
  • Q15: Write purpose of laser detector.
    Ans: A laser detector helps in identifying laser beams in bright light conditions.
  • Q16: What is the purpose of laser transmitter?
    Ans: The laser transmitter emits the laser beam used for leveling.
  • Q17: Define grade laser level.
    Ans: A grade laser level is used to set precise slopes for construction projects.
  • Q18: What is the difference between Fixed and variable RPM?
    Ans: Fixed RPM keeps a constant rotation speed, while variable RPM allows adjustments based on project needs.
  • Q19: Define RPM.
    Ans: RPM stands for Rotations Per Minute, indicating the speed of rotation of the laser head.
  • Q20: What is rotary laser level?
    Ans: A rotary laser level emits a continuous rotating laser beam to create a reference plane.
  • Q21: What is the difference between Line and dual beam laser level?
    Ans: A line laser level emits a straight beam, while a dual-beam laser level projects both horizontal and vertical beams.
  • Q22: What is Line Laser level?
    Ans: A line laser level projects a straight reference line onto a surface.
  • Q23: What is Dot laser level?
    Ans: A dot laser level emits a single or multiple reference dots on a surface.
  • Q24: What is the purpose of eyepiece?
    Ans: The eyepiece helps in focusing and aligning the laser beam.
  • Q25: Write two disadvantages of laser level.
    Ans:
    • ➔ Requires power source.
    • ➔ Limited visibility in bright light without a detector.
