Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “ DIY RTD for a DMM.” With a fortnight’s struggle, I completed the design of 4 mA to ...

iTemp TMT31 RTD-head, temperature transmitter with Pt100/Pt1000 sensors for analog, 4-20 mA signals provides high-accuracy measurement, flexibility and ease-of-use, safe operation, and l ong-term ...

The reference design is structured into three main blocks, featuring three integrated circuits that form the complete transmitter signal chain. The ADS1220, a high-precision analog-to-digital ...

Either case will result in incorrect measurement. The other way is to wire the RTD input to a mA converter and use a signal splitter to provide two independent mA signals. Raj Binney, measurement and ...

Conclusion Smart factory automation engineers have growing expectations of industrial temperature sensors, including smaller size, flexible communications, and remote configurability. This article ...

AutomationDirect has added two new frequency signal conditioners. The new SCU-2200 universal analog-to-frequency converters from ProSense accept milliamp, voltage, RTD, thermocouple or potentiometer ...

Figure 3. A voltage signal produced by a Pt100 RTD in response to increasing temperature. The AFE amplifies and conditions the low amplitude RTD signal before the analog-to-digital converter (ADC) ...

This paper studies the impacts of transmitters power levels on spectrum reconstruction performances in order to monitor a wideband spectrum. A sub-Nyquist blind sampling scheme based on the Modulated ...
