Tuning Fork Level Switch / Tuning Fork Level Switch
Tuning fork level switch, because the amplitude is adjustable, easy to measure different states and density of the material, suitable for a variety of silo solid material level and various containers within the liquid level of the fixed-point detection alarm or control.
Solid materials: fly ash, cement, stone powder, plastic granules, salt, sugar, etc.
Liquid medium: Technical parameters such as water, acid, alkali, mud, fuel, oil, milk, alcohol, beverage, etc. Output form: two sets of normally open and normally closed contacts; 0/10mA working pressure: ≤1.0Mpa. Material temperature: ≤300°C
Material density: ≥0.2g/cm3 Material particle size: ≤10mm Explosion-proof grade: ExdIIBT4 Protection grade: IP65 Material: Various brands of stainless steel Connection: Thread 11/2′′ Flange DN50 Installation method: Side or top loading principle introduction:
The tuning fork level switch is a new type of position control switch. It mainly relies on a tuning fork to measure the height of the material level through the vibration principle. The tuning-fork level controller works by vibrating the tuning fork at a certain resonant frequency through a pair of piezoelectric crystals mounted on the tuning fork base. When the tuning fork is in contact with the measured medium, the frequency and amplitude of the tuning fork will change. These changes are detected by the smart circuit, processed and converted into a switching signal.
Features Tuning fork level switch has the characteristics of long service life, stable performance, safety and reliability, strong adaptability, no need of adjustment and maintenance-free, etc. It is widely used in metallurgy, building materials, chemical industry, light industry, food and other industries. Bit process control.
It is not affected by foam, turbulence, or gas. It is suitable for fixed alarm or control of the solid material level of various silos and the liquid level in various containers.
For solid materials, mainly free-flowing medium-density solid powders or granules are measured. For example, fly ash, cement, sand, stone powder, plastic granules, salt, sugar, etc.
For liquid materials, it mainly measures explosive and non-explosive dangerous liquids, corrosive liquids (acid, alkali solution, etc.) high viscosity liquid water, acid, alkali, mud, pulp, dyes, oils, milk, liquor, beverages, etc. . The tuning fork level switch has a wide application, mainly for powders and small particles with a wide range of density, such as the detection of the inlet and outlet of the dust collector, the measurement of the dust level of the dust collector, plastic, rubber powder, flour , All kinds of food crops, food, chemical products, etc. limit measurement.
For a variety of liquid properties: such as slurry, viscous, easy to foam, corrosive and other media limit detection.
Precipitated Calcium Carbonate
Uses: Can be used as filler in rubber, plastics, paper, paint and ink industries. Widely used in organic synthesis, metallurgy, glass and asbestos production. It can also be used as a medium seeding agent for industrial waste water, a antacid for stomach and duodenal ulcers, a detoxifying agent for acidosis, a SOâ‚‚ eliminating agent in SOâ‚‚-containing exhaust gas, a dairy cattle feed additive and an anti-sticking agent for oil felt . It can also be used as a raw material for tooth powder, toothpaste and other cosmetics.
Usually used as a filler, widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc., as a filler to increase products The volume is reduced, and the production cost is reduced.
Light Calcium Carbonate is made of limestone, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc. It can also be used in organic synthesis, metallurgy, glass and asbestos production.
The particle size of light calcium is smaller than that of Heavy Calcium Carbonate, the oil absorption is larger than that of heavy calcium carbonate, and the price is higher than that of heavy calcium carbonate. They are all commonly used fillers in latex paint, and they are best used together. Light calcium is better in terms of sedimentation, but its oil absorption is greater than that of heavy calcium, and the price is generally more expensive than heavy calcium. Although it is not as stable as heavy calcium, it is stable. Even for exterior wall paint, its application amount is also very large. of.
