Hygienic Temperature Measurement for Demanding Processes
The Rosemount 68Q Sanitary Temperature Sensor is designed specifically for hygienic process environments where temperature measurement must be combined with strict requirements for cleanability and sanitary design.
It is suitable for food and beverage, pharmaceutical, and life-science processing, providing a flexible RTD solution for applications where contamination control and reliable temperature measurement are important.
Designed for Easy Sanitary Installation
The Rosemount 68Q uses a Tri Clamp sanitary endcap that allows easy installation and provides multiple immersion length options from 1.0 to 9.5 inches (25.4 to 241.3 mm).
Its aseptic process connection is designed for CIP applications and dead-pocket-free measurement, helping support hygienic process operation and cleaning procedures.
Built for Food, Pharmaceutical and Life-Science Applications
The 68Q is engineered for industries where sanitary construction and surface finish are critical.
The sensor and stainless steel connection head options can meet 3-A Standards, while the wetted parts can optionally be electropolished to satisfy specific surface-finish requirements.
Reliable Construction for Process Temperature Measurement
The sensor capsule is welded into a 316 stainless steel sanitary endcap and stem assembly, providing a robust construction for hygienic process environments.
The Rosemount 68Q supports a temperature range of -50 to 200 °C (-58 to 392 °F), making it suitable for a broad range of sanitary process temperature applications.
Calibration for Improved Measurement Performance
The Rosemount 68Q supports calibration schedules using Callendar-Van Dusen constants, helping improve overall sensor performance and temperature measurement accuracy.
A variety of enclosure and connection head configurations are also available, allowing the sensor to be adapted to different installation requirements.
