Model HTS

Thermocouple, Sulfur Processing Service, Compact, ATEX, IECEx

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 to accommodate a wide range of process connections starting at 2 inch Class 150 raised face flange. 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 50 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 primary thermowell, 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 HTS cylindrical body design offers multiple size configurations that allow for minimal impact of weather shroud designs, including the Temperature Extension option.

The all 316 Stainless Steel HTS is built to meet each customer’s specific installation requirements, such as thermocouple type and insertion length. Installation tools are available, and recommended to accurately produce the refractory borehole in the correct size and alignment needed by the refractory thermowell and HTS Thermocouple assembly.
