How Does an RTD Work?

An RTD works by using a basic principle as the temperature of a metal increases so does the resistance to the flow of electricity An electrical current is passed through the sensor the resistance element is used to measure the resistance of the current being passed through it

RTD (Pt100 Pt1000) FAQs

Q - I need a new RTD sensor but dont know what type I've been using can you help? A - The first step of identifying an RTD is finding out how many wires it has (2 3 or 4) you can then connect the RTD to a multimeter it should read between 107 - 110Ω at room temperature if it is a pt100 However if it is a pt1000 you should get a reading of 1007 - 1100 Ω which confirms that it is a Pt1000
