The TR21 and TR22 Series resistance thermometers (direct mounted or with thermowell) can be integrated into all standard processes. The devices’ hygienic design is verified by 3-A auditing and EHEDG certification. The TR21 is characterized by its space-saving design and quick electrical connection, and have Pt100 or 4–20-mA output signals. With the TR22, users can choose between all common standard signals, such as pt100, 4–20 mA, HART protocol, Foundation Fieldbus and Profibus PA outputs. — Wika Alexander Wiegand SE & Co.
