Figure 2. A block diagram of an RTD industrial temperature sensor. An RTD translates a physical quantity (temperature) into an electrical signal and is typically used to detect temperatures between ...

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 20mA, ...

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 ...

For applications using SIP operations-where steam at 121 °C (250 °F) is used to sterilize equipment-the sensor uses a reference material with a Curie Point of 118 °C (244 °F). When the SIP process ...

Multiplex Large RTD Sensor Arrays For Lower Parts Count Sept. 18, 2000 Resistance temperature detectors (RTDs) are among the most versatile and accurate of the commonly used temperature sensors.

Calibration resistors R4 and R5 along with the RT1 and RT2 RTD sensors can sink this current when the corresponding GPIO pin is driven low. When not used, the GPIO pins are tri-stated.

Temperature sensor uses Nickel RTD technology The Nickel RTD temperature sensor has a linear positive temperature curve with almost twice the sensitivity of a Platinum sensor and can be supplied in a ...
