Sensor: Rosemount 65B Sanitary RTD Sensor

Rosemount Series 65B integral mount temperature sensors are designed for use in BioPharm and Hygienic applications when fitted with Hygienic In-Line Systems which does meet sterile/aseptic requirements according to EHEDG and 3A guidelines. This Hygienic In-Line System is particularly suitable for temperature measurement in small pipes beginning with DN 10 to DN 15. Larger In-Line housings are also available as standard up to DN 80. The compact and dead-pocket free sensor design is easy to install and allows to maintain process integrity during exchange of sensor forcalibration or replacement purposes. The close dimension tolerance of sensor to weld-in pocket inside the In-Line housing reduces the response time obviously.Those RTD sensors are available as complete assemblies including connection heads or extension cable and process connection thread G1/2-in. (1/2-in. BSPF), thermowells and mounting fittings. All components are made of Stainless Steel for easy-to-clean ability in CIP/SIP applications. The In-Line system housing is electropolished as standard and available with material certificate 3.1B upon request. The use of In-Line system allows a quick mounting by the use orbital welding device. Especially with small pipes or later installations the In-Line System offers important advantages to hygienic mounting in comparison with conventional installation with standard sleeves.

This offering is designed to be used in complete temperature assemblies that include Rosemount 248 and 644 Head Mount Temperature Transmitters built in wide range of connection heads. In addition the sensor can be ordered as a compact, complete assembly with cable as cold end termination. The RTD sensors meet most critical parameters of international standards - DIN EN 60751 incorporating Amendments 1 and 2. All sensors are available in a variety of lengths and ranges with terminal block or flying leads.
