OPTITEMP TRA-H61 with VARIVENT® connection
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.
The OPTITEMP TRA-H61 features quick response time, reliability and excellent measurement stability. Its reduced sensor tip guarantees high measurement accuracy, even in small diameter pipes. The temperature assembly is also optionally available with a replaceable Pt100 measuring insert. Its G1⁄2 thread for hygienic adapters leaves freedom of choice for the process connections. The hygienic temperature sensor is available with VARIVENT®, dairy screw (DIN 11851), SMS 1145 as well as different weld-in sleeves. It is resistant to cleaning agents used in CIP and SIP procedures. The RTD sensor assembly is also available in a version for high-pressure jet cleaning with hot water (IP69).
