The TN2303 is an industrial temperature sensor with an integrated four-digit display for direct process monitoring. It uses a Pt 1000 Class A sensing element and supports a -50...150 °C measurement range. Its 30 mm installation length and 1/2-inch NPT external thread provide a practical solution for industrial piping and machinery. Two digital outputs, one analogue output and IO-Link provide flexible control and communication options. The sensor is designed for liquids and gases and offers high pressure resistance.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The red/green four-digit display provides clear local indication of process temperature. LED indicators show switching status for quick identification of active outputs. Three programming buttons allow direct configuration at the sensor. The upper housing can be rotated to improve readability after installation. IO-Link provides remote configuration and diagnostics.
The Pt 1000 Class A element provides stable temperature measurement according to DIN EN 60751. The sensor supports a wide -50...150 °C measurement range. Two digital outputs can be configured for temperature-limit monitoring. An analogue output can provide a continuous temperature signal. IO-Link allows process-data access and parameter management.
The 1/2-inch NPT external thread provides a robust process connection for compatible US-style threaded installations. The 30 mm installation length provides compact process immersion. The M12 connector provides reliable electrical connection. Gold-plated contacts improve connection reliability in industrial environments. The high-pressure construction makes the sensor suitable for demanding fluid systems.
