Product Description

Product Description

XK-508 RF capacitance switch is intelligent level switch. It utilizes RF capacitance measuring technology and digital calibration technology and overcomes the two difficulties of great temperature drifts and hard calibration. "Digital calibration technology" is especially designed for this product and brings great convenience to end-users. It will further promote the capacitance level switch to be used in much wider in various industries.

This product is easy to operate with the setting press key to set the lower and upper limit. Flexible controlling method, normally close/open contacts can be chosen freely. It has overcome the shortcomings of probe rod attachments or material splashing which may affect measurement. Under these rug service conditions, XK-508 capacitance switch can work normally. No moving elements in the checking parts, anti-shocking, insulted PTFE applied in probe rod; high temperature and high pressure resistance, anti-corrosion, not-easy being attached.

Structural Principle

Sensor probe is mounted at top or side of vessel. The probe rod and vessel wall is formed an electrical capacitor. When it is empty, the medium is air; as the liquid or material rising and probe rod being totally immerged, the dielectric constant between probe rod and vessel wall will change, and electric capacitance increase. Electronic circuit will detect the increment of capacitance and meanwhile output a switch value to be used in alarm or control.

Typical applications

Cereals processing: for flour and wheat grain level
Feed processing: for soybean meal level
Thermal power industry: for coal ash level
Building materials and glass industry: for lime and glass cullet level
Foundry machinery industry: for cement level
Hydraulic machine industry: for lubricating oil level
Chemical industry: for Polyester, Polyurethane, acid and alkali level
Water treatment industry: for sewage water level
