Liquid level switch, also known as the water level switches, liquid level sensor, as the name suggests, is used to control the liquid level switch.From the form mainly divided into contact and non-contact.
Commonly used non-contact switch with capacitive liquid level switch, touchBall float liquid level switchThe most widely used.Electrode type liquid level switch, electronic liquid level switch , capacitive liquid level switch, also can use contact method
XK-507 RF admittance level switch is a new level instrument. With advanced RF admittance technology, it has conquered the defect that capacitance level transmitter cannot eliminates influence of conductive medium attachment. Reliable in operation, resistant in heavy attachment, it is almost suitable for almost all industrial fields. In addition, it is easy to install, free maintenance, low cost and widely applied in the industries of petroleum, chemical, metallurgy, pharmacy, electric power, food stuff and paper making etc.
An RF Admittance level sensor uses a rod probe and RF source to measures the change in admittance. The probe is driven through a shielded coaxial cable to eliminate the effects of changing cable capacitance to ground. When the level changes around the probe, a corresponding change in the di-electric is observed. This changes the admittance of this imperfect capacitor and this change is measured to detect change of level.
