14. 1 1 1 Introduction Measuring A resistance thermometer consists of a resistance temperature detector Temperature with probe RTD and a resistance measuring instrument an RTD module Resistance RTDs are passive transducers that function on the principle that the resistance of a pure metal is proportional to its temperature An RTD probe consists of a wire of constant cross section and known length which is wound around a core of insulating material and enclosed in a protective housing The probe type RTD is usually stem sensitive that is it must be immersed sufficiently to affect the full length of RTD wire wound around the core Other types of probes available include the miniature ti p sensitive types for access to tight areas thin film types for quicker sensing and washer shaped types for easy mounting surface temperature measurement TheSeries 505 RTD Input module pulses a small amount of current through the RTDs attached to it The module measures the voltage generated by the current through the RTDs and then determines the resistance Series 505 RID The RTD Input module see Figure 1 1 provides eight RTD inputs in a Input Module single wide Series 505 format It is compatible with two three and four wire RTDs with automatic lead wire resistance compensation for three wire and four wire RTDs 505 7038 o 1002765 Figure 1 1 Series 505 RID Input Module 1 2 Product Overview SIMA
