Advanced differential pressure sensors for industrial applications
Superior Sensor Technology announced the industry’s first differential pressure sensors for industrial applications that support up to seven selectable pressure ranges in one device. Designed for a wide range of applications, the company’s new ND Series sensors support pressure ranges as low as 62.5 Pa/0.25” H2O to as high as 345 mBar/5 psi with an accuracy within […]
What are accuracy, error and repeatability in sensors?
Accuracy and precision are commonly confused terms. In fact, ISO 5725 (1994) uses two terms “trueness” and “precision” to describe the accuracy of a measurement method. Precision identifies the grouping or closeness of the readings. In contrast, trueness indicates the closeness of the test results to a reference or true value. This is more commonly […]
High-precision, low-profile medical sensors are designed as PCBs
TDK Corporation presents a new range of highly accurate differential pressure sensors (part number B58621V*), designed as printed circuit boards. The sensors are designed for measurement ranges of 16 mbar full-scale (FS), 100 mbar FS and 7 bar FS, with an absolute accuracy of up to ±1 percent FS at temperatures from -20 °C to […]
How do you want to monitor your health measurements?
Providing options was one of the driving forces behind some of the products introduced at the virtual CES 2021. For example, Nexvoo Healthcare announced an ergonomic breathable office desk chair that featured a built-in 3D armrest with a health monitor. By pressing a single button in the armrest, it displays heart rate, blood oxygen level, […]
Contactless rotary position sensor for benchtop and test & measurement apps
NewTek Sensor Solutions offers the RV series of rotary position sensors that measure and provide feedback on the rotary displacement of rotating elements in industrial benchtop and test and measurement applications. While featuring a full 360° mechanical range, these RVDTs provide an output proportional to shaft rotation over a range of ±30° or more in […]
What is the difference between piezoelectric and piezoresistive pressure sensing?
Piezoelectric is the property of a material to generate a voltage when mechanical force is applied to it. In contrast, the piezoresistive effect is the property of a material’s resistivity to change when subjected to a mechanical force. In either case, the mechanical force or stress can be compression, tension or a bending force. Ceramic […]
TDK introduces revolutionary MEMS-based CO2 gas sensor platform
TDK Corporation announces the InvenSense TCE-11101, a miniaturized ultra-low-power MEMS gas sensor platform for direct and accurate detection of CO2 in-home, automotive, IoT, healthcare, and other applications. The TCE-11101 introduces new technology that expands TDK’s sensor leadership into new applications and solutions, as part of the new SmartEnviroTM family. Its small size and low power […]
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 […]
Temperature sensor accuracy improved with custom packaging for platinum thin film elements
Temperature sensors are one of the most widely applied measurement technologies. As technology advances and industrial processes become more complex, devices continue to require a higher level of accuracy in temperature sensing across multiple industries. TE Connectivity (TE) has been able to provide critical temperature sensing solutions for a variety of applications. In an effort […]
