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 […]

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 […]
