The TN2511 is a compact temperature sensor with integrated display designed for industrial temperature monitoring. It uses a Pt 1000 Class A sensing element according to DIN EN 60751. Its 45 mm installation length and M18 × 1.5 internal thread provide flexible mounting with suitable process adapters. The sensor combines one switching output with a scalable analogue output and IO-Link communication. Its red/green display and three-button operation provide convenient local process monitoring and configuration.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The four-digit red/green display provides clear visibility of the measured temperature. LEDs indicate switching status and operating conditions. Three programming buttons provide intuitive local configuration. The upper housing can be rotated by 345 degrees for better viewing. The colour-changing display can help distinguish normal and critical temperature ranges.
The Pt 1000 Class A element provides accurate temperature measurement. The sensor covers a -50...150 °C measuring range. One switching output provides programmable temperature-limit control. The analogue output can be configured for continuous temperature transmission. IO-Link provides additional configuration, diagnostics and process-data communication.
The M18 × 1.5 internal thread is designed for connection through suitable process adapters. The 45 mm installation length provides practical immersion into the process. This arrangement provides flexibility when different process connections are required. The M12 connector provides a standard industrial interface. The sensor is suitable for liquids and gases.
