ALDK-400 intelligent RF admittance level switch is a fundamentally intelligent RF admittance level meter. This series of products are high-end products designed based on the principle of RF admittance, which have the advantages of high stability, accurate measurement and wide application. Compared with the traditional RF admittance level meter, this series of products use modular design and are equipped with LCD commissioning module, which can automatically obtain and display the current value of the measured level without using any peripheral auxiliary equipment, and provide users with more reliable measurement data. The LCD commissioning module has dual functions of commissioning and displaying, to enable users to read the data concisely and intuitively and facilitate commissioning.
Typical Applications
· Power plant: Coal pile, raw coal bin, fuel bunker, reservoir, waste gas purifi cation tank, bin pump, ash silo, and oil tank.
· Pulp and paper: Raw material silo, storage tower, drying drum, and chemical material storage silo.
· Oilfield: Crude oil or refi ned oil storage tank, three-phase separator, sedimentation tank, sewage tank and oilwater interface, and drilling mud tank.
· Water treatment: Reservoir, sewage tank, water treatment tank, sedimentation tank, deep well, and drinking water pipeline.
· Chemical industry: Crude oil distillation tower, raw material and intermediate silo, reaction tank, ammonia water tank, solid silo, and separator.
· Metallurgy: Ore silo, ore crusher, raw material silo, auxiliary material silo, blast furnace, alumina powder silo, and electrolytic cell buffer tank.
· Cement: Stone silo, raw material silo, cement silo, pulverized coal silo, and slag storage silo.
· Others: Quarry, food, pharmaceutical, environmental protection, shipbuilding and other industries.
Characteristic Parameters
· Intelligence: The operating range can be adjusted automatically, with indicator light display. The product has system error self-checking function, with indicator light display, and its accuracy is very high when no moving parts are installed horizontally, and it is suitable for measuring viscous materials.
· Anti-feed-retaining: The unique circuit design improves the anti-feed-retaining performance.
· Power supply range: DC24V 100mA and AC220V 50/60HZ.
· Relay capacity: DPDT, 220VAC, 5A non-inductive and 3A inductive.
· Adaptability: The operating temperature range of the probe is -184° C~260° C, and the temperature resistance of the circuit part is -40° C~80° C.
· Sensitivity: Less than 0.3PF.
· Adjustable delay: 0~60 seconds.
· Stability: High stability output; resistant to fly ash, falling materials, vapor, crystallization, and waxing.
· Maintenance-free: No moveable parts; no easily worn parts; infrequent cleaning, maintenance, and commissioning.
· Operability: With panel design concept, after the normal installation, the instrument automatically calibrates the operating point and operates the convenient electrical connection, which can improve the working effi ciency of the operator.
· Explosion-proof grade: Intrinsically safe Exia IIC T4-CT6, Flameproof Exd IIC T4-CT6.
