Principal of Operation

RF admittance technology is the next generation of capacitance based level sensors.

 

It detects the presence or absence of material surrounding the probe based on changing capacitance within a circuit as a result of the dielectric property of the material being sensed. When the presence or absence of material is detected the relay output changes state to indicate the appropriate condition.

 

In addition, unlike strict capacitance level sensors the Model AP/APX RF admittance point level sensor also employs a driven shield circuit that effectively ignores material build-up along the sensor probe should it occur.

Application and Use

The Model AP/APX is a point level sensor using RF admittance technology. These level switches are suitable for detecting the presence and absence of powder, granular, liquid and slurry materials in a wide range of industries. Mounted on bins, tanks and silos from the top or side, the filling and emptying of vessels can be controlled using the Model AP/APX as the unit generates fail-safe alarms (on power failure) providing overfill or dry run protection.
