Heavy-duty, 0.500″ (12.7mm) to 0.250″ (6.35mm), direct immersion sanitary sensor. Available as an RTD or thermocouple.

Heavy-duty defines the Model S40. The 1/2″ diameter stem and 1/4″ diameter tip section are designed to withstand high velocity and/or viscous fluids while still providing a fast 3.5 second time constant required for high-temperature short time (HTST) pasteurization processes.
