The document provides an overview of the features and characteristics of the Verschmutzungsanzeiger AE series products manufactured by Internormen. The Verschmutzungsanzeiger AE is an electrical/optical-electrical contamination indicator suitable for various applications. It has a high tolerance for pressure and temperature, and can measure pressure differentials up to a maximum operating pressure of 420 bar. Additionally, the product is waterproof and dustproof.
This document provides technical data for the INTERNORMEN AE series of dirt indicators (Verschmutzungsanzeiger). These devices are designed as electrical or combined optical/electrical pressure differential indicators for hydraulic filters. The series includes models from AE 30 to AE 80, featuring various contact configurations and LED options. This manual is written in German.

|---|---|
| Maximum Operating Pressure | 420 bar |
| Maximum Pressure Differential | 160 bar |
| Installation Torque | 125 Nm |
They are pressure differential indicators that trigger electrical signals and/or optical LEDs based on filter clogging.
They use a green LED for normal operation and a red LED to indicate that the filter element needs changing.
