SMART-SENSING RESEARCH BUOY IS POWERED BY TIDAL ENERGY


A smart-sensing research buoy for continuous ocean data collection, powered by tidal energy harvesting technology from Nagasaki University, has been developed by Kyocera Corporation. A paid trial service for this


innovative solution using Kyocera’s IoT technology is underway. As part of this initiative, Kyocera will collaborate with Nitto Seimo Co. to provide customers with a total solution including cloud-


based, real-time ocean monitoring,


buoy installation, maintenance and retrieval operations. The buoy includes a tidal power


generation system that utilises ocean currents to rotate an onboard turbine, generating electricity. Even with weak currents, the system can generate


power and store it in an onboard battery. The buoy is equipped with Kyocera’s communication modules, which transmit sensor data every five minutes. Internal sensors collect information such as internal temperature, humidity, acceleration, motor rotation speed, battery level, GPS location, and signal strength. The external sensors can measure


a wide range of oceanographic data, such as current speed and direction, salinity, chlorophyll concentration, turbidity, dissolved oxygen (DO), and water temperature. This flexibility allows customers to select sensors that best suit their specific data collection needs.

DISPLACEMENT SENSOR WITH SPRING- LOADED PROBE FOR HYDRAULICS SECTOR


INELTA Sensorsysteme has developed a displacement sensor for hydraulic applications. This has digital electronics based on LVDT with a probe and internal spring. Model LVDT-IHDT works with digital signal processing in a wide supply voltage range of 9...32 VDC. Both the measuring length and the output signals with current or voltage can be programmed on site using an external handheld device. An IO-Link interface is in preparation. This is vibration-resistant up to 30g, suitable for a temperature


range of -25˚C to +85˚C, and achieves protection class IP6K9K (ISO 20653). The high-precision digital displacement transducer is designed for pressure ranges up to 400 bar. In addition, bypass holes in the bearing ensure that the hydraulic fluid can flow past the sensor. On request, sensor


properties such as flange, supply voltage and pressure range can be customised.

A NEW SENSOR FOR TORQUE AND ANGULAR POSITION MONITORING


New from Sensor Technology is the robust SGR523, a state-of-the-art digital rotary torque sensor equipped with an integrated incremental angle encoder. According to the company, this addition to the TorqSense SGR series sets a new benchmark for precision in torque and angular position monitoring across various industrial applications. Featuring non-contact strain gauge technology, its high-


resolution angle encoder delivers up to 10,000 pulses per revolution with a resolution of 0.009˚, making it ideal for applications requiring meticulous torque-angle analysis, such as mechanical testing, automated assembly and process control. The SGR523’s advanced capabilities enable engineers to detect mechanical anomalies, such as rotational stiction or thread damage, by analysing torque versus angle plots. This dual- parameter monitoring is crucial for quality assurance in manufacturing processes, including bottle cap tightening and bolt fastening. In addition, the


sensor’s ability to monitor torque at specific shaft angles aids in identifying potential issues in process control applications; and its high-resolution angle measurement also facilitates precise motion control. Key features include: torque measurement range from 175 mNm to 20 Nm; accuracy of ±0.1%; high mechanical overload capacity of 400%; overrange reading capability of 250%; high digital sample rate of 4000 samples per second; digital outputs: RS232 and USB (standard); CANbus and Ethernet (optional); bi-directional angle and rotation count; and speed measurement up to 9000rpm. It is also compatible with TorqView Advanced Torque Monitoring Software and has a lifetime warranty.

enable rapid integration into industrial machines and control systems. According to the company, Confocal Chromatic


Two new compact confocal controllers have been added to Micro-Epsilon’s confocalDT range of confocal chromatic measurement systems. Building on the success of the compact controller introduced last year, these enable even higher precision for non-contact distance and thickness measurements on almost all surfaces in industrial environments. The new confocalDT IFC2411 and 2416


confocal controllers are compatible with all confocal sensors in the company’s portfolio, while setting new standards in precision and speed. Modern interfaces

sensor technology offers significant advantages over laser sensors. These use a white LED light source, not laser, which is much more stable and has lower noise on reflective surfaces. They measure in direct axis so can measure against very shiny or even mirrored surfaces, and they are able to measure on transparent and liquid surfaces without problems. The versatile confocalDT IFC2416 controller


offers a measuring rate of up to 25 kHz, achieved through a greater LED light intensity. This enables precise, stable measurements at high speed, even on challenging materials and surfaces. Its compact design makes it ideal for high resolution (up to 2nm) distance and thickness measurements. Due to the multi- peak measurement function, even multi-layer thickness measurements (up to five layers) can be carried out on transparent objects. At just 460g, the IFC2416 controller is also


versatile: it is compatible with all Micro-Epsilon confocal sensors, so that the measuring range, base distance and special sensor properties such as vacuum suitability, measuring angle or beam path, can be chosen as required. The confocalDT IFC2411 controller delivers


high precision measurements at a resolution of 2nm and has an adjustable measuring rate of up to 8 kHz. Due to a wide range of interfaces, including a new Ethernet connection, the controller offers maximum flexibility for integration into machines and systems. The housing is up to 300% smaller than comparable controllers and weighs just 335g, enabling it to be mounted on a DIN rail in small control cabinets. The introduction of the direct Ethernet


interface completes an impressive lineup of interface options available for the IFC2411 controller family, the company adds.
