Kongsberg GLA100/5SSSA2

Type: Marine high-precision FMCW radar level sensor, specially designed for cargo tank and ballast tank level monitoring.

Power Supply: Intrinsically safe operating power, maximum voltage 15.6 VDC; equivalent parameters Ceq=0.42μF, Leq=11μH.

Explosion-proof Grade: Ex ia IIC T4, Class I Div.1 Groups A-D, certified for hazardous flammable gas tank area applications.

Measurement Principle: Adopts frequency-modulated continuous wave (FMCW) radar non-contact measurement, no medium contact, no wear and pollution.

Measurement Accuracy: Typical ullage measuring precision up to 5 mm, ensuring stable and accurate level data.

Structure Material: Wetted lens made of PTFE material; external housing adopts AISI 316 stainless steel, excellent corrosion resistance for oil and chemical medium environments.

Protection Grade: IP66 enclosure, adaptable to severe marine outdoor and deck working conditions.

Signal Output: Dedicated digital bus signal output, matched with GLK100 processing unit; sensor head is not equipped with 4-20 mA analog output.

Operating Temperature: Wide temperature adaptation range of -40℃ ~ +80℃.

Core Features: Completely solid-state design without any moving mechanical parts; supports still-pipe installation to eliminate measurement interference from internal tank structures; equipped with anti-condensation lens to adapt to humid tank environment.

Application Scope: Widely used in ship cargo oil tanks and ballast tanks; fully compatible with Kongsberg K-Gauge tank gauging system.

Kongsberg GLA100/5SSSA2 Installation Steps

Pre-Installation Inspection

Check whether the equipment model and serial number conform to the design and procurement specifications. Inspect the sensor housing, PTFE lens and flange for cracks, scratches and mechanical damage. Verify the validity of the explosion-proof certificate. Inspect the internal condition of the tank still pipe to ensure it is clean and free of welding slag, debris and blocking obstacles.

Mounting Position Confirmation

The sensor is installed on the top of the cargo tank. Avoid central tank areas and internal structural barriers to ensure unobstructed radar beam propagation. Still-pipe mounting is the standard recommended scheme for tanker scenarios. Confirm that the size of the tank mounting flange matches the sensor dimension requirements. Ensure the tank is fully depressurized and gas-purged before construction.

Mechanical Installation

Place a qualified sealing gasket between the sensor flange and the tank base. Install the GLA100 vertically to keep the lens facing straight down into the still pipe. Fasten flange bolts in diagonal cross sequence with standard torque to avoid flange deformation caused by over-tightening. Keep the sensor vertical with a mounting tilt deviation controlled within ±1°.

Equipment Grounding

Use copper cables of no less than 2.5 mm² to connect the ship’s protective ground to the special grounding terminal of the sensor. Ensure reliable low-resistance metal connection. Do not take flange bolts as the sole grounding path to eliminate grounding hidden dangers.

Intrinsically Safe Cable Laying

Adopt certified Ex ia intrinsically safe field cables for connection between GLA100 sensor and GLK100 processing unit. Strictly comply with loop parameter limits (Ceq=0.42 μF, Leq=11 μH). Separate signal cables from high-voltage power cables to avoid electromagnetic interference. Use qualified explosion-proof cable glands at the cable inlet to ensure IP66 enclosure tightness. Do not switch on the 15.6 VDC intrinsic safety power before wiring is completed.

Wiring Termination

Complete intrinsic safety power and bus signal wiring inside the sensor terminal cavity. Strictly prohibit the mixed wiring of non-intrinsic safety circuits. After wiring inspection, fasten the terminal cover and cable glands completely to guarantee explosion-proof performance and enclosure protection level.

GLK100 Processor Installation

Install the GLK100 processing unit in the safe-area control cabinet. Complete bus communication wiring between the processor and GLA100 sensor, connect the processor working power and finish standard grounding construction.

Power-On and Commissioning

Power on the GLK100 processing unit first, then supply 15.6 VDC intrinsic safety power to the GLA100 sensor. Run self-diagnosis through K-Gauge system software, and calibrate tank parameters including ullage range, still pipe size and tank height. Verify liquid level measurement accuracy, and perform false echo suppression calibration if there is beam interference.

Functional Test

Compare radar measurement data with manual sounding values to verify measurement accuracy. Check the stability of measured values under different liquid level conditions, confirm no system alarms, and verify normal data upload to the ship tank gauging system.

Final Acceptance Check

Recheck flange sealing condition for no leakage. Inspect the fastening state of all cable glands and explosion-proof covers. Archive commissioning parameters, test data and installation records to complete the whole installation process.
