For a balanced bridge usual setting is with R2 = R1, and R3 around the middle of the range of the RTD. So for example, if we are going to measure between 0 and 100 °C (32 and 212 °F), RTD resistance will range from 100 Ω to 138.5 Ω. We would choose R3 = 120 Ω. In that way we get a small measured voltage in the bridge.
RTD may refer to: Science and technology. Real-time data; Residence time distribution; Resonant-tunneling diode; Round-trip delay time, in telecommunications;
Four-point measurement of resistance between voltage sense connections 2 and 3. Current is supplied via force connections 1 and 4. In electrical engineering, four-terminal sensing (4T sensing), 4-wire sensing, or 4-point probes method is an electrical impedance measuring technique that uses separate pairs of current-carrying and voltage-sensing electrodes to make more accurate measurements ...
The probe is completely non-metallic. The fibre optical sensor is completely non-conductive and offers complete immunity to RFI, EMI, NMR and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use. [1]

"It had so many different genres mixed together that, truly, I thought, 'This could either be amazing or a f---ing disaster,'" Moore said of Ghost. "Either way, it's usually the kind of juice that ...
[1] NTC thermistors are widely used as inrush-current limiters and temperature sensors, while PTC thermistors are used as self-resetting overcurrent protectors and self-regulating heating elements. An operational temperature range of a thermistor is dependent on the probe type and is typically between −100 and 300 °C (−148 and 572 °F).
The holiday season is well underway, which means your calendar is probably filled up with social events ranging from Secret Santa gift swaps to work holiday parties. All of that socializing means ...
