Thermocouple sheath cover

摘要

A sheath cover for a quartz thermocouple sheath has an outer surface which includes silicon carbide. The silicon carbide has a greater adherence to deposits than quartz. The cover thus essentially eliminates deposit flaking and avoids the particulate contamination associated with conventional quartz thermocouple sheaths. The cover includes first and second half sections and a slip ring. The cover is easily installed over the sheath by placing the half sections around the sheath and then sliding the slip ring into place around the half sections.
