Full/Empty Limit Switch

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, where it is employed for the protection of pumps and the control of filling systems. It offers non-intrusive ultrasonic measurement through the wall as well as precise distinction between empty and liquid filled pipes. The simplified installation method of the 2-wire system can be carried out even during system operations. Due to a pipe fastening system made of plastics the sensor can be relocated quickly and easily. 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 medium- or pipe temperature range lies between -40 and 140°C. A versionfor the use in hazardous areas is available.
