The TD2903 is a compact hygienic temperature transmitter designed for process installations using a 2-inch sanitary clamp connection. Its 30 mm installation length provides a compact sensing solution for shallow process points. The transmitter uses a Pt1000 Class A sensor with a -50...150 °C measuring range. It provides a four-digit LED display, 4–20 mA analogue output, and IO-Link communication. The stainless-steel hygienic construction supports reliable operation in food, beverage, and process applications.
