The OPTITEMP TRA-C61 is a compact resistance sensor (RTD) with optional integrated transmitter for hygienic use in limited space. The temperature sensor is particularly designed for food & beverage applications. This includes the 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. It complies with FDA and EC1935/2004 regulations. Its G1⁄2 thread for hygienic adapters leaves freedom of choice for the process connections. The compact RTD sensor is available with VARIVENT®, dairy screw (DIN 11851), SMS 1145 as well as different weld-in sleeves.
