Model HTS Thermocouple

The Delta Controls Model HTS Thermocouple is designed for the primary purpose of reliably protecting a vessel and its refractory lining from excessive temperatures.

The HTS is designed for installations unable to accommodate the recommended 6 inch process connection of the Model HTX. The HTS provides long term accuracy and reliability in sulfur processing service.

The design of the HTS is the result of attention to detail, more than 45 years of experience, and numerous field installations.

The thermocouple junction is isolated from corrosive and invasive gases by using a constant low-flow flush gas circulating across the junction.

The flush gas is kept at a pressure higher than the internal reactor pressure to mitigate the migration of process gases through the element well, body, or seals.

Process gases that enter are carried away by the flush gas. The metered flush gas flow has an insignificant effect on the accuracy of the temperature measurement.

The Model HNP, consisting of ceramic fiber rings sized for the customers nozzle, is required with the use of the HTS.

For most applications, Model HTX is preferred as it offers the highest reliability of any thermocouple.

The HTS provides a highly reliable alternative compatible with smaller process connections for installations unable to accommodate the recommended 6 inch process connection of the Model HTX.
