SLDL5216 Horn Type Radar Level Meter

SLDL5216 low-frequency horn type radar level meter is an advanced radar-type liquid level/material level/material level measuring instrument with a measuring distance of up to 70 meters. The pulse radar level meter can be used for level measurement of storage tanks, intermediate buffer tanks or process containers and various silos, and outputs 4...20mA analog signals.

 

• pulse modulated radar adopts advanced non-contact measurement, and the pulse radar level meter is made of extremely stable materials

• Measure the level of liquid and solid media

• Can measure all media with dielectric constant > 1.8

• Measuring range 0...70m

• 4...20mA output/HART (two-wire/four-wire system), etc.

• Not affected by pressure, temperature changes, inert gas, vacuum, smoke, noise, steam, dust, and other working conditions

• Not affected by changes in medium density, viscosity and temperature

• Process pressure can reach 160bar, process temperature can reach 800℃ (with isolation accessories), accuracy ±5mm

•Horn type radar level meter two-wire technology is an excellent alternative to differential pressure instruments, magnetostrictive, radio frequency admittance, and magnetic flap instruments

•Sensitive measurement, fast refresh speed, easy installation, firm and durable, maintenance-free

• Adopts microwave pulse measurement method, and can work normally within the industrial frequency band. The pulse wave radar has low beam energy and can be installed in various metal or non-metal containers or pipes without any harm to the human body or the environment.

Applicability to process conditions: The process interface of the horn type radar level meter can meet the process conditions that occur, including process pressure, process temperature and chemical properties of the medium.

Suitability for environmental conditions: The instrument is suitable for general and other environmental conditions according to DIN/EN/IEC/ANSI/ISA/UL/CSA61010-1.

Mounting position: Select a mounting position that is convenient for installation and wiring, and also for subsequent removal of the display and adjustment module. The housing can be rotated by 330° without the use of any tools. In addition, the display and adjustment module can be rotated in steps of 90°.

Welding work: Remove the electronics from the horn type radar level meter sensor before welding work on the vessel. This will prevent damage to the electronics due to inductive coupling. Before welding, ground the measuring probe directly via a rod or rope.

Use: For threaded versions, do not screw in the housing! Tightening can damage the swivel mechanism of the housing. When screwing in, use the hexagonal tool provided for this purpose.

Moisture: You should guide the connecting cable downwards before threading the cable, thereby additionally preventing moisture from entering your instrument. This way, rainwater and condensation will flow downwards. This is particularly suitable when installing the instrument outdoors, in rooms where moisture can enter (e.g. due to cleaning processes) or in cooling or heating vessels. Make sure that the protection class of the instrument is maintained so that the housing remains closed during operation and is secured if necessary.

Vessel shape: Always install the capacitive measuring probe vertically or parallel to a counter electrode as far as possible. This applies in particular to non-conductive media. In horizontal round tanks, spherical tanks or other asymmetrically shaped tanks, non-linear level values are obtained due to the different distances to the vessel wall. For non-conductive media, use a sealing tube or linearize the measuring signal.

Condensation: If condensation occurs on the vessel cover, the running liquid can form bridges and thus lead to measuring errors. Therefore, use a shielding tube or a longer insulating tube. Its length depends on the amount of condensation and the flow of the medium.

Cable entry - NPT thread Cable gland:

Metric thread

The cable gland is screwed into the instrument housing with metric thread before leaving the factory. It is plugged with a plastic plug to protect it during transport. The plug must be removed before making the electrical connection.

NPT thread

For instrument housings with self-sealing NPT threads, cable glands must not be screwed in at the factory. Therefore, for protection during transport, the free cable entries are closed with red dust caps. Before commissioning, you must replace these protective caps with approved cable glands or close the openings with suitable blind plugs.
