Overview
Rosemount™ 68Q Sanitary Temperature Sensor
The Rosemount 68Q Sanitary Temperature Sensor is an industry-standard, resistance temperature detector (RTD). This sensor is engineered to provide flexible and reliable temperature measurements in hygienic process environments for the food and beverage,pharmaceutical and life-science industries. This RTD is designed with a Tri Clamp® sanitary endcap configuration for easy installation and its aseptic process connection is suitable for clean-in-place (CIP), dead-pocket free, measurement applications.
Benefits
* Designed for hygienic process environments to meet food and beverage, pharmaceutical and life-science industry demands
* Tri Clamp endcap provides immersion lengths from 1.0 to 9.5 inches (25.4 to 241.3 mm) for easy installation
* Withstands -58 to 392 °F (–50 to 200 °C) temperature range for application durability
* Aseptic process connections are suitable for clean-in-place, (CIP) dead-pocket free, measurement applications
* Surface finishes on sensors and SST connection heads meet 3-A® Standards to ensure reliable performance
* Variety of enclosure and connection head options offer application flexibility
* Sensor capsule is welded into the 316 SST sanitary endcap/stem assembly for performance stability
* Calibration schedules with Callendar-Van Dusen constants improve overall sensor performance and accuracy
* Provides option for electropolishing wetted parts to meet specific surface finish requirements
