Resistance Temperature Detectors (RTDs), which are a type of temperature sensor, are widely used in a variety of industrial applications due to their accuracy, repeatability, and stability. These devices measure temperature by sensing the change in electrical resistance of a material as its ...
Dry-block calibrators are stable temperature sources for calibrating sensors such as dial thermometers, resistance temperature detectors (RTDs) and thermocouples.These sensors are used for process manufacturing in many industries.They need to be checked or calibrated periodically. Watch the How to Calibrat...
A ratiometric configuration is a suitable and cost-effective solution for systems that use resistive sensors such as RTDs or thermistors. With a ratiometric approach, the reference and sensor voltages are derived from the same excitation source. Therefore, the excitation source does ...
RTDs are categorized by their nominal resistance at 0°C. A Pt100 sensor has a temperature coefficient of approximately 0.385 Ω/°C and a Pt1000 has a temperature coefficient that is a factor of 10 greater than the Pt100. Many system designers use these coefficients to get an...

aThe user must provide an external voltage supply and signal ground to the DOPTO OC Card via connector CON1. The external voltage must be in the range of 7 − 30 Volts dc. The DOPTO card installed in the RTDS rack to which the DOPTO OC is connected must be configured for 5 volt ...
• Limit the voltage drop to a safe level for the ADC or an additional filter network is required with an impedance high enough so that the ADC internal steering diode can handle the current caused by the overvoltage. • Use fault-protected multiplexers like TMUX7412F and TMUX7462F to ...
