The OPTITEMP TRA-H65 is a RTD sensor assembly with reduced thermowell and firmly welded clamp connection for 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. The sensor 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.
