Programmable Smart Sensor

A programmable IMU-based sensor system from Bosch Sensortec, Stuttgart, Germany, combines a gyroscope with an accelerometer that enables full customization. The BHI360 offers an integrated sensor fusion library that enables 3D audio with head orientation for personalized sound experiences as well as simple gesture recognition. It can be used in wearables and hearables, smart devices, and more. The sensor is provided in a compact 20-pin LGA package measuring 2.5 × 3 × 0.95 mm³. The sensor is a highly integrated, ultra-low power, smart 6-axis IMU consisting of a 32-bit programmable microcontroller.

Capacitive Bubble Sensor

Capacitive sensors from EBE sensors + motion, Leinfelden-Echterdingen, Germany, detect air bubbles in liquids. The capaTEC^® bubble sensor from detects air bubbles and discontinuities of liquids, regardless of the liquid and properties of the hose. Even with mechanical tolerances or changing hose sizes, the sensor’s detection performance remains constant, making it a robust and flexible solution for a wide range of industrial applications. When an air bubble passes the sensor the electric field changes, and the sensor detects the bubble. The sensor does not require specifically customized housings, which facilitates its use in a wide range of applications.

Noninvasive Bubble Sensor

Introtek, Edgewood, NY, has released a noninvasive air bubble sensor that incorporates the latest ultrasonic technology. The AD10 AirGuard combines an asserted self-test with continuous cyclical background self-test for added safety and risk mitigation. It has an advanced fail-safe design in which self tests are continuously performed without impacting sensor detection. Integral to the sensor’s assembly, the microelectronics controller features programmable algorithms for functionality control. Response times, time delays, and other functions are programmable to specific requirements. The company’s pulse-type ultrasound provides highly reliable, noninvasive air detection capabilities in critical applications where the safety of a patient or the integrity of a process is essential.
