Technical Description: ifm electronic PG2409
The ifm electronic PG2409 is a specialized electronic pressure sensor with an integrated analog display, designed for hygienic and process applications. Combining the reliability of an electronic sensor with the visual clarity of a traditional pointer gauge, the PG2409 is ideal for monitoring pressure in tanks and pipelines within the food, beverage, and pharmaceutical industries. Its flush-mount design ensures that no dead spaces exist, preventing bacterial growth and ensuring easy cleaning.
Engineering and Hygienic Performance
The PG2409 covers a measurement range of -1 to 25 bar. It features a G 1 Aseptoflex Vario process connection, which allows for a wide variety of hygienic adapters (EHTEDG, 3-A). The sensor is designed with a high-strength ceramic measuring cell that handles pressure peaks and abrasive media with ease. With an IP69K protection rating, the PG2409 is fully resistant to high-pressure steam cleaning and aggressive chemical agents used in CIP (Clean-in-Place) processes.

Operational Benefits
The dual-display system of the PG2409 offers a significant advantage: the pointer gauge remains visible even if power is lost (depending on the internal buffer), while the digital display provides precise values and parameterization options. The IO-Link interface enables digital process data transmission and remote configuration, making it a future-proof solution for automated process plants. Its robust construction ensures long-term accuracy and minimal maintenance requirements.
