1 Security
1.1 Laser Level
1.1.1 Aiming Laser
The laser level gauge is provided with a visible laser and is emitted from the front of the instrument for aiming at the measured medium. The Visible Laser is a Class 2 laser, based on the following criteria:
·IEC60825-1:2001 "Radiation safety of laser products"
·EN60825-1:2001 "Radiation safety of laser products"
FDA 21 CFR Ch.I § 1040:2004 (US Department of Health and Human Services, Federal Regulations)
Secondary laser products:
Do not stare into the laser beam and do not aim at others if it is not necessary. The eye will instinctively protect the eyes by turning or blinking.
Laser wavelength: 635nm, <1mW, <15mm@5m
1.2 Warning
Do not open the instrument cover when the power is on. Only professional technicians can open the cover for operation, wiring, calibration and programming.
1.3 Measurement principle
The laser level gauge has a built-in visible laser aimed at the measured medium. A built-in high-precision high-resolution timing device measures the round-trip time between the infrared laser at the launch point and the measured medium. Then L = t * c / 2 (t is the round trip time, c Light speed). The laser level meter is a non-contact measurement. Since the laser can penetrate the glass, the laser level meter can be well protected and can be used for harsh environment measurement (high temperature, high pressure, high humidity, high dust). Since the laser emission angle is very low (<0.2°), the laser level meter can measure the narrow space level and can accurately measure the irregular surface.
The laser radar level gauge is placed inside a well-designed protective cover, making the laser radar level gauge available for harsh environment (high temperature, high pressure, high humidity, high dust) measurements. The well-designed protective cover makes the lidar level gauges installable in any environment and installed in any angle and manner.
