The old saying “if it ain’t broke, don’t fix it” cautions against tampering with something that performs reliably and regularly proves its worth. Arguably, this advice applies to the circuit design ...

An RTD (resistance temperature detector) is a temperature sensor that operates on the measurement principle that a material’s electrical resistance changes with temperature. The relationship between ...

Both the RTD itself and its accuracy must be considered when selecting the RTD sensor. The temperature range varies with element type, and theaccuracy denoted at calibration temperature (usually at ...

An earlier Design Idea described how to linearize the output of an RTD (resistance-temperature-detector) sensor and how to calculate the resistor values using a spreadsheet (Reference 1). That idea ...

Figure 8 This diagram shows a complete working ΔΣ ADC with pressure sensor and temperature sensor inputs. Source: Maxim Integrated In the core ΔΣ ADC block diagram (Figure 4), there is a ...

RTD sensors are available using two-, three-, and four-wire configurations, which differ in their use of sense wires (Fig. 1a, 1b, and 1c, respectively).

Further, its operating temperature range of -55°C to +160°C makes it application-compatible with requirements for the use in motor oil and hydraulic systems. Measurement Specialties has the capability ...

It also cuts the number of RTD array connections (feedthroughs) from 4N to 4 + N. For 28 sensors, the resulting savings are 2N − 2 − N = 26 inputs and 4N − 4 − N = 80 feedthroughs.

Endress+Hauser’s iTHERM TrustSens hygienic resistance temperature detector (RTD) is a self-calibrating temperature sensor that can be used in bio/pharma processes to eliminate the risk of undetected ...
