rosemount 68q 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.
