Conax Technologies Roll Temp Sensor Assemblies provide repeatable monitoring of surface temperatures on drums, rollers or other moving surfaces. They are ideal for detecting temperature variations in continuous process applications, such as plastic-film processing, wire manufacturing and painting processes. Compact and easy to install, Roll Temp Assemblies are furnished with Conax B2 terminal heads. Brass contact buttons, flush-mounted in a spring-loaded plunger, provide excellent thermal transfer to the temperature sensor. They are available in all base metal thermocouple calibrations. Three models are offered.","High-Temperature Assembly – Catalog Type HTRT * Temperature range: -90°F to +700°F (-68°C to +371°C) * Similar in construction to Type HSRT except that continuous surface contact is assured by use of a Conax Technologies spring-loaded packing gland assembly * Speeds up to 1000 ft.\/min. * Available in all base metal calibrations * Not available in dual or triple configurations or in special tolerances Example: For a Chromel-Alumel thermocouple, the catalog number would be HTRT-K.
