| Reference Material | |||
| Your choices are... | |||
| Platinum | The most common metal used for RTDs - for measurement integrity platinum is the element of choice. | ||
| Nickel / Nickel Alloys | Very common metal used, economical but not as accurate as platinum. | ||
| Copper | Occasionally used as an RTD element. Its low resistivity forces the element to be longer than a platinum element. Good linearity and economical. Upper temperature range typically less than 150 degrees Celsius. | ||
| Other | Gold and Silver are other options available for RTD probes - however their low resistivity and higher costs make them fairly rare, Tungsten has high resistivity but is usually reserved for high temperature work. | ||
| Search Logic: | All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches. | ||
| Reference Resistance | When matching probes with instruments - the reference resistance of the RTD probe must be known. These are the most standard options available. | ||
