LO-300

레이저 스캔 오일 필름 검출기

LO-300은 레이저를 이용해 수면이나 지면을 스캔해 고감도로 유막을 탐지합니다.

레이저 및 보안 카메라(옵션)가 온라인으로 기름 누출이 감지 되면 알려줍니다.

카메라 유닛(옵션)으로 알람을 감지하고, 알람 신호 전후에 캡처된 영상을 저장할 수 있습니다.

Easily accessible monitor with 3.5 inch color LCD with touch panel

Various operations are available such as reflection level diagnosis, instrumental error judgment, oil film detection etc.
The LCD backlight is automatically turned off when there is no operation on the touch panel for 15 min. or more. This function prolongs lifetime of LCD and saves energy.

■3.5 inches color LCD with touch panel

Variety of functions

WARNING and ALARM, 2 alarm settings are available.
LO-300 watches the cumulative elapsed time of laser module when it reaches certain level then requests the maintenance work.

Detection distance from 0.3m to 4m

LO-300 enables oil film detection under a fast sample flow with ripples to an extent, detection distance up to 4m between the detector and the water surface is possible.
In case of the still-water surface, up to 6m is available.
The laser scanner module rotates around the optical axis thus rejecting local light scattering by the wave ripple to detect the mean intensity of the reflection from the surface.

■Functional schematic

Detection area setting is available

The area detection function performs judgment by the rate of the oil film present on the detection area.
Alarms caused by reasons other than oil leakage accident (accumulated oil film ,iron bacteria, insect, fish and others) can be excluded.

Laser life time is four years

The recommended maintenance cycle is four years (improved to double compared our existing product).
LO-300 is always watching the cumulative elapsed time of laser module, when it reaches to the limit, can display “exchange“ of a laser.
The optical device in the main body has our original hanging structure (bellshaped structure), which assures vertical installation of the instrument even with a slight inclination of the detector, allowing easy installation work.

Security Camera (Option)

LO-300 with camera unit (option) enables to record the video when LO-300 detects the alarm and stores the image on the surface captured before and after alarm signal. The image with time stamp can validate that oil leakage is true or false.
