The Baumer PT20S is a compact industrial RTD (Resistance Temperature Detector) temperature sensor with integrated transmitter, designed for robust temperature measurement in factory and process automation applications. It combines a Pt100 sensing element with a built-in 4 … 20 mA analog transmitter (and in some variants, IO-Link Dual Channel), making it suitable for direct connection to control systems, PLCs, and data acquisition hardware without needing an external transmitter unit.
Its all-welded stainless steel construction with high corrosion resistance (AISI 316L) supports customer-specific immersion depths up to 3000 mm, and it withstands harsh industrial environments with high humidity and vibration. Depending on configuration, the sensor can be supplied with multiple process connections (e.g., G 1/2, G 1/4) and electrical terminations (M12 or DIN connectors).
