WebJMS RTD color codes are per ASTM E1137 and IEC 751 specifications. A resistance temperature detector determines the temperature by measuring resistance. The sensing element is usually a small diameter wire manufactured so that its resistance will change in a known and consistent manner. To WebRTD wiring configurations There are three types of wire configurations, 2 wire, 3 wire, and 4 wire, that are commonly used in RTD sensing circuits. A 2-wire configuration with a compensating loop is also an option. 2 wire RTD connections The 2 wire RTD configuration is the simplest among RTD circuit designs.

There are several very important details that must be specified in order to properly identify the characteristics of the RTD: 1. Material of Resistance Element (Platinum, Nickel, etc.) 2. Temperature Coefficient 3. Nominal Resistance 4. Temperature Range of Application> 5. Physical Dimensions or ... See more Several metals are quite common for use in resistance elements and the purity of the metal affects its characteristics. Platinum is by far the most popular due to its linearity with temperature. Other common materials … See more The temperature coefficient of an element is a physical and electrical property of the material. This is a term that describes the average resistance change per unit of temperature from ice point to the boiling point of water. … See more Depending on the mechanical configuration and manufacturing methods, RTD’s may be used from -270ºC to 850ºC. Specifications for … See more Nominal Resistance is the prespecified resistance value at a given temperature. Most standards, including IEC-751, use 0ºC as their reference point. The IEC standard is 100 ohms … See more WebView temperature readings and adjust settings directly on these RTD probe transmitters. To communicate with programmable logic controllers (PLCs), they have a built-in transmitter with two outputs. One output can send a digital switching signal or use IO Link protocol with the addition of an IO Link controller (not included). The other can send a digital switching … small new home plans
