The OPTITEMP TRA-H61 is a RTD sensor assembly with reduced thermowell for hygienic applications in the food & beverage industry. The hygienic temperature sensor with stainless steel connection head and fast responding sensor tip is particularly suitable for temperature measurement of beverages, dairy products or pasty food or. It is therefore made of stainless steel (1.4404 / 316L) with an industry-specific surface finish of the thermowell of Ra ≤0.8 μm. The temperature assembly complies with FDA and EC2004/1935 regulations.
