MEMs transducer packaged in ultra-compact PCB assembly
Posifa Technologies introduced its new PVC4100 series fully calibrated MEMS Pirani vacuum transducer. Designed for cost-effective OEM integration, the device consists of a surface-mount MEMS Pirani sensor and microcontroller-based measuring electronics — all packaged in an ultra-compact PCB assembly featuring a connector-terminated wire harness. The PVC4100’s sensor element is based on Posifa’s second-generation MEMS thermal […]
What’s the difference between 2-, 3-, & 4-wire RDT sensing?
The difference is measurement accuracy. Using 2-wire resistance temperature detector (RTD) sensing provides good accuracy (maybe), the accuracy of 3-wire sensing is better, and 4-wire sensing provides the best accuracy. In addition, there’s the option of using Wheatstone bridge topologies to improve the performance of 2- and 3-wire RDTs. This FAQ begins with a review […]
Compact direct drive actuator boasts 1.25μm resolution
The compact, electric cylinder or linear voice coil actuator measures 38.1 mm (1.500 in.) in diameter, with a 12.7 mm (0.500 in.) stroke, and a housing length of 69.9 mm (2.750 in.) long has been released by Moticont. This new SDLM-0038-070-01-01M Linear DC Actuator features high repeatability, 1.25-micron resolution, a continuous force of 14.5 N […]
Temperature, humidity sensors/signal conditioners target IoT apps
Renesas Electronics Corporation is changing the way designers build sensor-connected IoT applications with a range of new solutions targeted at faster design cycles, improved accuracy, and reduced system cost. In addition to the new HS4XXX family of relative humidity and temperature sensors, Renesas is introducing the ZSSC3281 sensor signal conditioning (SSC) IC for highly accurate amplification, digitization, and sensor-specific […]
Where is my stuff?
In today’s supply chain situation, this has to be among the most frequently asked questions . However, even under what may have been considered normal times prior to COVID-19, it still is a legitimate question. Tracking shipments that are critical or essential may allow more expensive tracking solutions but if the cost is reasonable, many […]
Keysight’s Innovation Challenge is back for 2022
The student competition for IoT designs to mitigate climate change and reduce energy consumption is back on track for 2022. Registration opens April 4. After a two-year COVID-19 hiatus, Keysight Technologies has rebooted its IoT Innovation Challenge. The Keysight Innovation Challenge 2022 student competition challenges students to design IoT devices that sense our world and […]
What sensors are used in today’s and tomorrow’s HVAC systems? Part 3
Part 1 provided background on the evolution of heating, ventilation and air-conditioning (HVAC) systems and the increased use of sensors and Part 2 elaborated on sensing in more advanced HVAC systems. In this third and final part, government and industry organization’s effort to change HVAC systems and the impact on sensing will be explored. In […]
What sensors are used in today’s and tomorrow’s HVAC systems? Part 1
When Willis Carrier designed a system of fans, ducts and perforated pipes, which became the first modern electric air conditioner (AC) in 1902 (120 years ago), sensing was not part of the bill of materials. Devon Brock, Manager of Product Knowledge and Training, Sensors Group at TE Connectivity provides some insight into subsequent AC systems. […]
