The process connection of the SLDL5216 horn type radar level meter can meet actual process conditions, mainly including process pressure, process temperature, and chemical properties of the medium.
In accordance with DIN/EN/IEC/ANSI/ISA/UL/CSA61010‑1 standards, the SLDL5216 horn type radar level meter is suitable for conventional and special industrial environments.
Choose a location that facilitates installation, wiring, and future disassembly of the display and adjustment module. The housing can be rotated 330° without tools, and the display module can be rotated in 90° steps.
Remove electronic inserts from the sensor before welding on the vessel to avoid damage caused by inductive coupling. Ground the measuring probe with a rod or rope before welding.
Do not screw screws on the housing of the SLDL5216 horn type radar level meter, as this may damage the rotation mechanism. Use a dedicated hexagonal tool for installation.
Route the connecting cable downward before threading to prevent moisture from entering the instrument, especially for outdoor installation and humid environments. Maintain the instrument’s protection rating by keeping the housing sealed.
Install the probe vertically or parallel to a counter electrode. For horizontal tanks, spherical tanks, or asymmetric vessels, non‑linear level readings may occur. Use a sealing tube or linearize the signal for non‑conductive media.
Condensation on the vessel cover may cause measurement errors. Use a shielding tube or extended insulating tube with length determined by condensation volume and medium flow.
•Metric Thread: Cable glands are pre‑installed with plastic plugs. Remove plugs before electrical connection.
• NPT Thread: Sealed with red dust covers at delivery. Replace covers with approved cable glands or proper blind plugs before commissioning.
