At Sensor Expo 2019, Edoardo Gallizio from product marketing for MEMS & Sensors in the Americas at STMicroelectronics demonstrates a complete predictive maintenance reference design. Multiple sensors are part of the monitoring where some sensors are mounted directly on a spinning wheel to continuously measure vibration. The sensors gather the data, a microprocessor accesses the […]
What happens when the earth moves?
At Sensors Expo 2019, Satya Dixit from Applications and Systems Engineering at Rohm Semiconductor explains the capabilities and applications for an earthquake sensor module. The earthquake detection module (BP3901) has correctly detected 200 out of 205 previous cases of seismic events. Waveform differences between a seismic event and an external event such as a collision […]
What sensors can be used in an AC system?
At Sensors Expo 2019, Devin Brock, Manager of Product Knowledge and Training for Sensors Solutions at TE Connectivity, explains the numerous opportunities for a variety of sensors in an air conditioning (AC) system. The working table top heating ventilating and AC (HVAC) system from New Product Innovations has wired and wireless sensors from TE Connectivity […]
Vibration sensors monitor machine health for the IIoT
VocalZoon announced the launch of its next-generation predictive maintenance sensors for the Industrial Internet of Things (IIoT). VocalZoom’s sensors measure the vibrations emitted by industrial machinery to predict and prevent mechanical failures before they occur. Because they can monitor machine health without touching the equipment, VocalZoom sensors cover a greater array of equipment and use […]
How can sensors be used for predictive maintenance?
At Sensors Expo 2018, Antonio Cirone from ST Microelectronics demonstrated and discussed different approaches for predictive maintenance for motors, fans and more using accelerometers, environmental and acoustic MEMS sensors. The demo has two motors. The green motor is balanced properly and the red motor is out of balance. Spectrum analysis of the triaxial accelerometer output […]
How can you track vibration?
At Sensors Expo, Pete Hulbert, a Test & Support Engineer from Silicon Designs explains one of the applications of his company’s industrial grade microelectromechanical system (MEMS) accelerometers using a tabletop track with moving cars. Three accelerometers are attached to the track in different locations (turns in the track) to determine the vibration in the track […]
How do sensors make a smart crane safer?
Watching a crane operator elevate and transport a heavy load over a significant distance to a precise location with an articulated crane is always a fascinating and thought-provoking activity. With today’s concerns about job safety, how is safety handled in this process? Safety begins with the skill of the crane operator but today’s sensors and […]
Fly inside a building with the help of vibration sensors
Due to gravity, when skydivers jump out of an airplane, they immediately fall toward the earth, falling several thousand feet in less than a minute before opening their parachutes. For indoor skydiving, where you float less than 100 feet above ground level, there is no parachute and a rather sophisticated process is involved that uses […]
Kaman Measuring launches digital differential impedance transducer
The Measuring Division of Kaman Precision Products Inc. has released a new eddy current measurement system, the Digital Differential Impedance Transducer (DDIT). The DDIT is designed to provide a digital interface for high speed eddy current measurement systems, with resolution in the micro-inch range, at bandwidths as high as 60 kilohertz (kHz). It is ideal […]
What functions do sensors provide to drones?
Depending on the type of drone and its function, there can be a few essential sensors or an extensive number of sensors on board. Whether the drones are civilian or military craft, the sensors fall roughly into three categories: Make Them Fly, Make Them Work and Diagnose & Prevent Problems. Make Them Fly An inertial […]
