DRFK-98 RF admittance level swith
Introduction
DRFK98 RF admittance level switch is universal point control meter. he meter consists of a electronic unit, a explosion-proof shell and hard or flexible probe elements. Auxiliary in-phase driven probe should be added through the sensor, which solves the problem of material adhesion. It is stable and reliable, good versatility , no need maintenance. It is not affected by the density of the materials, the size of the particles, the chemical elements, the electrical conductivity, high temperature and high pressure, which can be widely used in the process control of the liquid level or material level of the liquid, solid, slurry and interface.
Product Application
Application industry: metallurgy electric power, chemical and petrochemical, water and sewage treatment, pulp and paper, food and pharmaceutical industries.
Measuring medium:
1.Liquid: fuel, solvent, acid, alkali, liquefied petroleum gas, water, etc.;
2.mixture: sewage, liquid waste, pesticides, solution, industrial products;
3.interface: the oil-water interface, alcohol / acid interface;
4.Foam: Latex foam, beer foam, soap bubble, etc.;
5.slurry: sludge, pulp, crude oil / bitumen, paint / grease, etc.;
6.powder: pulverized coal, fly ash, cement, lime, mineral powder, flour, etc.;
7.particles: plastic, alumina, fertilizers, drugs, and grains.
8.block material: crushing coal, lime, coke, ore
Product Characteristics
1.High versatility: It can be used in various occasions. Detect a variety of process materials, for example: fly ash, particle, powder, liquid, slurry, conductive and non-conductive materials.
2.Anti-adhesion circuit: The anti-adhesion electronic circuits can eliminate false signals that the adhesion materials produced.
3.It has a universal probe, Steel wire probe and tablet probe, PPS, Teflon and stainless steel structure, which can be used under high temperature, high pressure and in liquid, powder, solid block materials and corrosive substances.
4.The probe is high temperature proof. The probe is suitable for the operating temperature from -40 ℃ to 200 ℃. The ceramic high temperature probe can also be used. The highest temperature that it can resists is up to 800 ° C.
5.Contact capacity: Large capacity relay contact outputs. The LED lights indicate the
working status. 0-30 second delay.
