Capacitive technology solves the edge detection problem that clear label sensors present. Reducing the size of the sensor allows it to address more applications. That was the goal when Lion Precision developed the LRD3120 Clear Label Sensor. The sensor has a remote sensing head that is only 14 x 18 x 24 mm and connects […]

Solar Energy Harvesting Powers Intra-Ocular Pressure Sensor
An Intra-Ocular Pressure Monitor (IOPM) device that is less than 1.5 mm has been designed for implanting in the eye of a glaucoma patient. Developed by researchers at the University of Michigan, the design uses a capacitive pressure sensor developed at the university, an integrated 0.07mm2 solar cell, a Cymbet EnerChip solid-state battery and other circuitry […]
Pressure Sensors Target Tough Measurements
While it is the most popular approach for pressure sensors, microelectromechanical systems (MEMS) technology requires considerable packaging enhancements to address liquid and corrosive gas measurements. In contrast, ceramic pressure sensors can more readily make these types of measurements. In its Ceracore UCS2 pressure sensors, Endress+Hauser uses Al2O3 (99.9 %), a highly resistant ceramic material. This allows the […]
Accurately Measure Inclination
Wind energy systems, solar thermal power plants, medical technology, and oil and gas extraction can all benefit from accurate inclination measurements. For these and other applications require angle measurement or constant rotary monitoring, Balluff’s recently introduced inclination sensors may provide the answer. The sensors measure the deviation […]
Optical vs. Ultrasonic vs. Capacitive Sensors: The Winner is…
For clear label sensing, Lion Precision has designed and built a machine to compare optical sensors, ultrasonic sensors and two types of capacitive sensors. The company uses all of these technologies in products it offers. With this evaluation tool, sensors that employed each of the four technologies were tested and compared using web speeds of […]
Sensors Embedded in the Driver’s Seat Could Monitor Driver Fatigue
Among the many problems that carmakers and their suppliers are investigating that new sensor technology might help solve is driver fatigue. An effective solution that is implementable in a vehicle and not just under laboratory conditions would have to be transparent to the driver. Plessey engineers think they have a solution. Using their EPIC sensor […]
AutomationDirect adds to capacitive proximity sensor lineup
AutomationDirect’s line of capacitive proximity sensors now includes 12mm metal round bodied DC models with shielded and unshielded mounting options, PNP, normally-open outputs, potentiometer adjustment and M12 quick disconnect. Unshielded 18mm DC plastic bodied models with selectable normally-open/normally-closed outputs feature logic auto detection. Additional unshielded 30mm models feature AC and DC versions with plastic housings […]
Squeeze a 6-mm Height Proximity Sensor into Industrial Applications
At only 6-mm thick, Baumer’s CFDK 25 capacitive proximity sensors are offered with five fixed sensing distances from 2 to 15 mm. The sensor fits in confined spaces such as low rise conveyors, automated handling equipment or industrial machinery for detecting wafers and PCBs on electronic production lines, for liquid level detection in laboratory processing, […]
Variable Capacitance Pressure Transducers Address Extreme Environment Industrial Apps
Available in pressure ranges from 1 to 10,000 psig, Setra Systems Model 209 variable capacitance pressure transducers offer users several choices. In addition to gauge, sealed gauge, or vacuum pressure options, output choices include: 4-20 mA, 0.5 to 5.5 Vdc, 1 to 6 Vdc or 0.5 to 4.5 Vdc output. The sensors have ±0.25% full-scale […]
Capacitive Sensor for Liquid Level Detection
Detecting liquid levels in confined spaces in machines and facilities can pose problems. For these types of applications, Baumer developed its CFDK 25 capacitive sensor. The 52.4 x 25-mm flat housing design has a height of only 6 mm and has an available mounting frame. In addition to attachment with two screws, the frame allows […]
