Pepperl+Fuchs introduces Ultrasonic Sensors for safety applications
Pepperl+Fuchs is expanding its factory automation portfolio with the all-new USi-safety ultrasonic sensor. Suitable for use in harsh environments and even for outdoor applications, this small but mighty sensor requires only a small amount of installation space. With safety certification in accordance with EN ISO 13849 category 3 PL d and as the only sensor […]
How to design an effective telehealth system
By Marcel Consée, Mouser Electronics Healthcare can be deeply personal, and direct contact between patients and medical personnel remains vital. However, taking the relationship between doctors and nurses out of the equation can sometimes make sense. Medical crises such as the global COVID-19 pandemic accelerate the adoption of telehealth methods, even though the original idea […]
Graphene-based flowmeter sensor measures nano-rate fluid flows, Part 3: The sensor
The first part of this article looked at the challenges of sensing nano-level flow rates such as found in the blood vessels. In contrast, the second part looked at graphene, an allotrope of elemental carbon at the heart of a new sensor used to measure those flows. This third and final part looks at the […]
Graphene-based flowmeter sensor measures nano-rate fluid flows, Part 2: The graphene context
The previous part of this article looked at the challenges of nanoflow sensors, especially with respect to blood flow. This part looks at graphene, which is the basis for the new sensor. Graphene is a material structure which did not exist until relatively recently. However, its constituent element of graphite – the crystalline form of […]
Graphene-based flowmeter sensor measures nano-rate fluid flows, Part 1: The challenge
When it comes to nearly all biological measurements, the ranges of many of the parameters of interest are orders-of-magnitude below those with which many engineers are familiar. Instead of megahertz or even kilohertz, the living-creature world is in the single or double-digit hertz range, such as the roughly 60+ beats per minute (BPM) for a […]
The working principle, applications and limitations of ultrasonic sensors
The ultrasonic sensor (or transducer) works on the same principles as a radar system. An ultrasonic sensor can convert electrical energy into acoustic waves and vice versa. The acoustic wave signal is an ultrasonic wave traveling at a frequency above 18kHz. The famous HC SR04 ultrasonic sensor generates ultrasonic waves at 40kHz frequency. Typically, a […]
Leuze presents the GSX, the world’s first combined fork sensor
With the new GSX combined fork sensor, Leuze is once again introducing a worldwide innovation. This product combines the advantages of light and ultrasonic sensors. The GSX sensor is exceptionally suitable for labeling machines used in the packaging industry. With the introduction of the GSX, the world’s first combined fork sensor, Leuze is continuing its […]
Ultrasonic sensors from Telemecanique Sensors
Unlike conventional sensing technologies, ultrasonic technology is not adversely affected by the type of material to be detected, the color or shape of the detection target, or the environmental conditions during detection. Suitable for packaging machines, material handling, and machine tools, ultrasonic sensing is based on the detection of a high frequency ultrasonic wave reflected […]
Toposens launches TS3 ultrasonic sensor
Toposens recently announced the release of their current flag-ship product TS3, a 3D ultrasonic sensor suitable for a range of applications in the autonomous systems market that require a strong need for reliable object detection and situational awareness. In comparison to common ultrasonic sensors, which usually measure the distance only to the closest reflecting surface, […]
