Ultrasonic Proximity Switch
The series SW 305 Ultrasonic Proximity Switches are ideally suitable for level monitoring applications. The Ultrasonic Sensors are available in different enclosures to detect various types of objects. The sensing range covers from 0.2 m to 20 meters. The output signal is either in the form of a switching signal or a linear output current or voltage signal. These sensors have the ability to perform in dry and dusty environments. The performance of these sensors is not affected by the presence of impeding materials like Ash, Soot, and Sawdust etc. These sensors are immune to electrical noise level generally present in the typical industrial environment.
These switches are offered in tubular metallic, acrylic & plastic enclosures. Standard models are available with integrated 2-meter long cable. Switches with built-in (Male) connectors (International M8/M12 size) for quick connections are also available.
All the Capacitive switches are provided with Reverse polarity, Overload, short circuit and false pulse protections. Rugged construction along with IP-67 grade of protection renders these switches to be very useful for liquid level monitoring applications.
The sensing distance specified for DS switch is considered with a white object having minimum 90% reflectivity.
SWITCHES WITH OPTICAL FIBRE
Special model of Optical Switches are available with an integrated Optical Fibre cable for flexible mounting and for sensing miniature objects / high temperature objects. This switch is of through-beam type and is available in H type enclosures.
These switches incorporate a precise and delicate piezo Ceramic Ultrasonic transducer pair. The sensors are available in open as well as sealed type transducers. The transmitter sends a modulated Ultrasonic Signal, which is reflected by the object. A microprocessor-based circuit precisely measures the time taken to travel the distance from object to sensor. Effective output signal (either linearly varying or switching type) is generated depending upon application.
