Non-intrusive full/empty limit switch at small diameter pipes (10...50 mm)

SONOTEC: The optimized ultrasonic limit switch SONOCONTROL 15 detects quickly and reliably whether a pipe is filled with liquids / liquid gases or not. The compact sensor is mainly used in plants of the pharmaceutical sector and the food industry. Here, the SONOCONTROL 15 is employed for the protection of pumps and the control of filling systems.

The known advantages of the limit switch, such as the non-intrusive ultrasonic measurement through the wall as well as the precise distinction between empty and liquid filled pipes, have been upgraded by further favourable characteristics. The simplified installation method of the 2-wire system for example, which can be carried out even during system operations, guarantees an optimal use of the device. Due to a new pipe fastening system made of plastics the sensor can be relocated quickly and easily. Furthermore, the advanced firmware assures a stable operating mode.

The required power supply is 12...40 VDC. According to the 4…20mA concept the switching status is represented by the current consumption of the sensor. The acceptable medium- or pipe temperature range lies between -40°C…+140°C. A particular device version of the SONOCONTROL 15 is also available for the use in hazardous areas.
