Product Specs
These sensor designs incorporate spring loaded probes that insure that the probes are in intimate contact with the thermowell. This improves performance by providing a conductive path between the probe tip and thermowell, as well as improving vibration resistance. Supplied in the four most popular connection head styles, Cast Iron, Miniature Aluminum, Hinged Aluminum and Sub-Miniature Aluminum, with ceramic terminal boards or optional transmitters, these sensors can be configured to work with most thermowell type applications. These sensors are supplied with 100 ohm, Class A DIN Platinum elements contained in stainless steel probes and spring loaded hex fittings.
should the sheath length of an RTD match the stem length of the thermowell or the insertion length of the thermowell?
Thank you for asking your question.
The sheath length of the RTD should match the stem length of the thermowell you are planning on using.
