In order to limit the sound beam of ultrasonic sensors, sensor specialist PiL Sensoren, which is part of the Inelta Group, offers special cylindrical sound reduce pipes for some of its ultrasonic sensors. These reduce the sound beam of the ultrasonic waves and reduce the scanning range at the same time. By limiting the sound waves using a defined hollow cylinder, interfering objects in the boundary area of the sound beam are masked out. This enables targeted focusing on the target object. To avoid scattering or absorption losses, the manufacturer matches the material and dimensions to the acoustic properties of the sound pipe. The shape and length of the attachment are adapted by PiL to the ultrasonic frequency of the transducer of an ultrasonic sensor in order to ensure precise and reliable measurements even in very narrow detection ranges through targeted frequency selection and alignment of the sensor in combination with the soundpipe. Typical areas of application for sound pipes include level measurement in pipes with very small diameters – for example in medical technology, in filling or capsule closing systems. In the case of sensors arranged very close together – such as in arrays for height profile monitoring – sound pipes are used not only to synchronize the sensors on the control side but also to suppress interference-related disturbances. PiL supports its customers in selecting and equipping the sensor technology with appropriate noise reduction pieces and also manufactures customer-specific special solutions on request.

For demanding industrial applications - for example in film extrusion lines - sensor specialist PiL Sensors (www.pil.de) offers robust ultrasonic sensors with M18 stainless steel housings. Designed for detection ranges from 50mm to 1,600mm, the P47 series distance sensors are available with fixed or factory-adjustable characteristics. The entire P47 series features fast response times, temperature compensation and a synchronization function for up to ten sensors. This makes these ultrasonic sensors ideal for high-precision distance measurements, for example in film blowing machines for extrusion film production. Synchronization prevents mutual interference between the ultrasonic signals of several sensors. Electrostatic discharges, which can occur during film drawing, are absorbed by the metal housing so that the electronics of the sensor are not affected. The manufacturer supplies the device series, which is manufactured in protection class IP65 and approved for a temperature range of -20°C to +70°C, with M12 connection and either switching or analog output. In addition to various connection sockets and cables, reflector angles for sound detour as well as sound reducers and reducing rings are available as accessories.

The sensor specialist PiL has optimized its economical, easy-to-install P48-30 series ultrasonic sensors and now offers a common Y-connector with M12 output for the transmitter and receiver. This allows the previously separate connections to be easily and practically connected to connect both sensor modules to the signal processing as one device using M12 sensor cables. The P48-30 model series is specified for non-contact detection of light, dark and transparent objects in a detection range up to 300mm. Its sound cone aperture of 15° ensures reliable object detection, which – unlike optical systems – is not affected by dust, smoke or refractive geometries. Any interruption of the detection area triggers a switching signal with a maximum switching frequency of 150Hz. Due to its short response time of 1ms, the P48-30 ultrasonic barrier is ideal for product or pack counting on conveyor belts even at high belt speeds. Its measurement sensitivity in the mm range also ensures the detection of very thin materials, for example for foil detection. The sensor modules, which are very compact with dimensions of 30x20x10mm and are manufactured in protection class IP67, can be used in a temperature range from -15°C to +60°C. The sensor modules can also be used in a wide range of applications. An LED integrated in the receiver unit is used for function display. A short product video is available at https://youtu.be/0WC01wbQrlQ. PiL offers comprehensive application know-how and responds flexibly to customer requirements at all times. And where application-specific parameterization is not sufficient, the manufacturer is also happy to support its customers on request with individually customized solutions. The development and manufacturing facilities of the specialist for industrial ultrasonic sensor technology are in Germany.

Ultrasonic sensors always emit their sound waves “straight forwards” by nature. However, the spatial conditions and installation location make it difficult to directly align the sensor housing with the object being monitored in many applications. Redirecting the sound waves using suitable angled reflectors is a practical solution for this problem. For example, it is not possible to make new installation openings for ultrasonic sensors in many containers whose interiors needs to be monitored. In these cases, the sensors can simply be fitted parallel to the wall of the container on terminal blocks and the sound waves emitted from the sensors can be redirected through an existing opening using 90° reflectors. PiL Sensoren, a leading specialist for ultrasonic sensors, offers tried-and-tested solutions and a comprehensive range of mounting accessories for these types of application. Alongside ultrasonic sensors suitable for every requirement, the PiL product range includes optimally aligned 90° plastic reflectors, focusing attachments, and flexible metal reflectors for adjusting the angle of the sound wave to the specific requirements of the application. If you have any specific requirements, please contact the application consultants at PiL. You will find contact details at www.pil.de/kontakt. Application know-how is key The reliability of measurement solutions not only depends on the use of robust sensor technology, but also on specific design features of the selected sensor models, their application-specific configuration, and correct placement. That is why PiL, as a specialist for industrial ultrasonic sensor technology, supports its customers with comprehensive application know-how, detailed consultation, and where required, is happy to carry out customized modifications of its products as required.

No other sensor technology has such a versatile range of applications as ultrasonic technology: In the industrial sector alone, its applications range from recording filling levels and volume flows and measuring distances, heights, and widths through to detecting objects and obstacles in dynamic processes. Yet depending on their specific application, sensors often require costly modifications in order to work reliably. Inadequate conditioning of the signals or faulty seals on the housing of standard sensors can not only result in unsatisfactory measurement results but also in the early failure of the sensors. Yet it is usually extremely expensive for companies to commission the production of suitable and appropriately robust sensors. PiL Sensoren GmbH offers its customers a happy medium in the form of cost-effective solutions. Thanks to its own development and production facilities in Germany, this manufacturer of ultrasonic sensors not only specializes in the production of a wide range of robust standard models but can also supply sensors that have been configured for specific applications. Due to its decades of experience in the production and adaptation of customer-specific sensors, PIL can offer a broad range of tried-and-tested solutions. The company’s engineers also use their comprehensive expertise in different fields of application to develop durable sensor solutions for use in challenging operating conditions that offer good value for money. The technical consultants at PIL would be delighted to provide comprehensive advice to any customers who are looking for sensor solutions for their specific requirements.

PiL Sensoren GmbH – pioneer of ultrasound technology – has developed the P49 model series for a fast startup. The manufacturer individually parameterizes these sensors to meet customer requirements. This saves users the time they usually need for setting up ultrasonic sensors on site for an application. The savings potential is considerable – especially when it is not just a matter of a few sensors, but a medium to large quantity. The P49 series includes three types of sensors (M18, M30 and cubic 80 mm x 80 mm) for ranges from 30 mm to 6 m, optionally with switch outputs or with current or voltage outputs. With preset, each customer gets their own item number, giving them a unique product that can always be traced back to them. This in turn prevents errors in the field caused by unauthorized or unqualified parameterization. And even if it needs replacing in the field, nothing needs to be adjusted. The plastic sensors with protection type IP67 are suitable for ambient temperatures of -20 °C to 70 °C. They are used in a variety of applications, such as filling level measurement for liquids and bulk goods, in logistics for collision protection and position control, as well as for container inspection, thickness measurement and presence control – for example in the paper, film and textile industries. PiL offers comprehensive application know-how and responds flexibly to customer requirements at all times. And where application-specific parameterization is not sufficient, the manufacturer is also happy to support its customers on request with individually customized solutions. The development and manufacturing facilities of the specialist for industrial ultrasonic sensor technology are in Germany.

PiL offers a range of mounting solutions for making ultrasound measurements in closed containers to reliably and precisely detect the contents or filling level even in challenging applications. Depending on the medium, ultrasonic sensors with metric thread can simply be screwed into the housing wall. It must be ensured that no resonance vibrations occur that could falsify the measurement results. This simple screw-in solution does the job for some applications. Elsewhere, more or less elaborate seals are necessary. The sealing material needs to be super tight and hygienic for food and pharmaceutical applications. The sensors are attached with nuts from the inside and outside. This makes it difficult to replace sensors when necessary: The container has to be opened and the locknut can get lost. This is where PiL has developed a special vibration and resonance-free housing which is firmly mounted to the opening in the container wall from the outside. This then means the sensor can be flexibly replaced at any time as required. Absolute tightness guaranteed. This solution is particularly recommended for applications where sensors have short service lives or those in which the medium must not be contaminated. It is used for monitoring liquids as well as bulk solids and is also suitable for foodstuffs, alkalis and acids, among other things. PiL offers this housing for most of its sensor series. The measurement solution reliability not only depends on the use of robust sensor technology, but also on specific design features of the selected sensor models, their application-specific configuration, and correct placement. That is why PiL, as a specialist for industrial ultrasonic sensor technology, supports its customers with comprehensive application know-how, detailed consultation, and where required, is happy to carry out customized modifications of its products as required.
