Cuttable RTD Temperature Sensors
Cuttable RTD Temperature Sensors SKU:CRTD
Description and Specs
Industrial Process and Sensor offers a wide range of RTDs.
We offer a full range of RTDs made to order that can fulfill your needs.

Our Cuttable RTD allows you to get an RTD that is a set lenght and cut it down for your needs
The length of the element is dependent upon the needs of the customer and the sheath that extends off of it is based off of the maximum length requirements that the customer requires. Thus allowing you to trim down your probe to fit snugly within a thermowell or an enclosed chamber.

We also offer small tubing cutter upon request
Advantages of platinum resistance thermometers:

  • High accuracy
  • Low drift
  • Wide operating range
  • Suitable for precision applications

Limitations:

  • RTDs in industrial applications are rarely used above 660 C. At temperatures above 660 C it becomes increasingly difficult to prevent the platinum from becoming contaminated by impurities from the metal sheath of the thermometer. This is why laboratory standard thermometers replace the metal sheath with a glass construction. At very low temperatures, say below -270 C (or 3 K), due to the fact that there are very few phonons, the resistance of an RTD is mainly determined by impurities and boundary scattering and thus basically independent of temperature. As a result, the sensitivity of the RTD is essentially zero and therefore not useful.
  • Compared to thermistors, platinum RTDs are less sensitive to small temperature changes and have a slower response time. However, thermistors have a smaller temperature range and stability.
