Designers who use inductive proximity sensors have a choice of high-performance signal-conditioning interface ICs, each offering different sets of features, functions, and capabilities. The first part of this article discussed some of the sensing opportunities and looked at an IC from Texas Instruments. This part looks at ICs from Renesas and Microchip Technology. Renesas IPS2550 […]
Sensor Tips
4-in-1 MEMS sensor measures gases, humidity, temperature and barometric pressure
Whether at home, in the office, or outdoors, we need to be confident that the air around us is clean and safe to breathe – COVID-19 has clearly highlighted the importance of air quality. Due to the particulates, gases, and even airborne viruses ubiquitously present in our modern environment, poor air quality has an increasingly […]
ICs for interfacing inductive sensors, Part 1
Designers who use inductive proximity sensors have a choice of high-performance signal-conditioning interface ICs, each offering different sets of features, functions, and capabilities. In two predecessor features (see References), we looked at the inductive proximity sensor and its basic operation (see References) but did not look at the electronic interface circuit for this widely used […]
How can the new temperature-sensitive COVID-19 vaccines’ temperatures be ensured?
The newly developed COVID-19 vaccines require low temperature storage to ensure their efficacy. For the Pfizer-BioNTech vaccine, the U.S. Centers for Disease Control and Prevention (CDC) specifically states that it should be stored in an ultra-cold freezer, thermal shipping container or refrigerator. The ultra-cold freezer’s temperature should be maintained between -80°C and -60°C (-112°F and […]
Tactile switch boasts 5 million cycles with 2.8N and 4N actuation force
C&K has done it again – first introducing the revolutionary KSC Tireless Endurance (KSC TE) with 10 million cycles at 1.6N, the highest in the industry. Now C&K has launched a 5 million cycle version with higher actuation forces at 2.8N and 4N – again making these miniature tactile switches the highest lifecycle switches available […]
An overview of absolute encoder communication protocols
Depending on the application, a controller or variable-speed electric-motor drive may need to measure any combination of rotor speed, position, and direction. Absolute encoders are a popular motion control choice with their ability to determine rotor position immediately at power on, while also being able to keep track of position during sudden power losses. With […]
Torque sensors feature non-contact technology
Saelig Company, Inc. has introduced the Sensor Technology TorqSense SGR510/520 Torque Sensors which use a four-element strain gauge bridge design with non-contact surface acoustic wave (SAW) detection. These sensors offer a 250% over-range reading capacity, allowing sudden spikes in torque to be measured and recorded accurately without clipping. The new design compensates for extraneous, inadvertent forces such as bending […]
Pressure transducer for harsh environments helps cut machine downtime
There is an increased demand among design engineers in the industrial and commercial transportation (ICT) and industrial space for reliable sensors and components that improve operational efficiency in hydraulic machinery and compressed gas applications. To serve this need, TE Connectivity (TE) has developed the M9100 pressure transducer. Based on TE’s proven Microfused strain gauge technology, […]
Hermetically-sealed LVDTs serve as OEM replacements for steam turbine systems
NewTek HAR Series of Hermetically-Sealed Linear Position Sensors provide critical position measurement in the monitoring and control of steam turbine valves in power plants. Ideal for power plant rehabilitation programs, these AC-operated LVDTs serve as OEM replacements for legacy applications, offering the same fit, function, and reliability as original units. Gas turbines use various valves […]
What is the future of the IoT Sensors Market?
In its report “IoT Sensors Market Research Report,” Market Research Engine expects the global IoT sensors market to grow from $10.08 billion in 2019 to $10.38 billion in 2020 at a growth rate of a mere 3.03%. The slow growth in 2020 is attributed to the economic slowdown worldwide from the COVID-19 outbreak. Expecting a […]
