RTD elements

RTD stands for Resistance Temperature Detector. Platinum RTD sensors are most often used because platinum has a near linear resistance versus temperature gradient. But also nickel resistors are available. Visit our website to read more about how RTD elements work.

Nickel, platinum or some other resistive metal, all measure electrical resistance that varies with the temperature. The output signal of this sensor type is created by passing a constant and measured current through the resistance. The temperature of the environment where the sensor is placed will then cause a voltage drop. It is important that the measurement current is as low as possible. When the measurement current is too high, the sensor itself will heat up and the output signal will be corrupted. A measurement current of 1mA will have no significant effect on the measurements.

Platinum sensors can be constructed in various forms. The construction varies according to the area of use. The biggest difference in construction are ceramic wound and thin-film resistors.
