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.
Time Constant / Response: Tri Clamp O.D. tube size 1-in. and greater: Less than 3.5 seconds required to reach 63.2% sensor response; Tri Clamp O.D. tube size 1/2- to 3/4-in.: Less than 1.5 seconds required to reach 63.2% sensor response; see full specs for complete specifications
Stability: Tri Clamp O.D. tube size 1/2- to 3/4-in.: ±0.08% maximum ice-point resistance shift following 1,000 hours at maximum specified temperature 392 °F (200 °C)
Lead Wires: Tri Clamp O.D. tube size 1-in. and greater: ±0.04% maximum ice-point resistance shift following 1,000 hours at maximum specified temperature 392 °F (200 °C)
Insulation Resistance: 500 x 10^6 ohms minimum insulation resistance when measured at 100 Vdc at room temperature�
Calibration Options: Customer-specified calibration point or schedule; calibration schedule with Callendar-Van Dusen constants�
