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 […]
How can you detect seismic waves?
At Sensor Expo 2017, Jacob Hicks, the assistant product manager for Omron Electronic Components’ Sensors unit shows the capabilities of the D7S, a vibration sensor that can detect seismic waves, and Itron’s Riva development board for wireless communications. Partnering with Itron, Omron’s D7S sits on top of Itron’s Riva board. The D7S contains an ASIC, […]
How can sensors determine machine health?
At Sensor Expo 2017, a ROHM Semiconductor expert discusses how several sensors including pressure, temperature, flow and level sensors connected through sensor node can help monitor a machine’s health or control a process. In the demo, each sensor node collects the data and uses wireless sub-gigahertz radio called Wi-SUN and transfers the data to a […]
Digital variable impedance transducer for noncontact linear position sensing
The Measuring Division of Kaman Precision Products, Inc., a manufacturer of precision non-contact position measuring systems, announces the digiVIT transducer. The digiVIT features a self-tuning bridge, which is capable of performing with nearly any sensor, from any manufacturer, as well as any conductive target. The transducer also features simple push button calibration, temperature compensation, and […]
