Product Description

Based on the non-dispersive-infrared technology (NDIR), ZILA GmbH has developed an inline-capable measuring system that permanently monitors the oil condition directly in the system. The optical measuring system consists of a multi-channel infrared measuring cell with associated electronics and peripherals. In this case, the molecules present in the oil absorb the infrared light at different wavenumbers due to their typical binding forms different degrees. Over the course of the operating life, these molecular properties change, whereby a signal change can be detected in certain regions of the infrared spectrum. The system thus provides continuous real-time information about the oil condition which should be comparable to laboratory measurements. The control and configuration of the electronics takes place via a user-friendly and graphical user interface. Digital outputs and a Modbus TCP interface allow easy integration into the plant control.

Easy commissioning and operation through graphical user interface

The sensor can be easily integrated into existing and new systems. Digital signals and Modbus TCP allow direct and easy connection of the sensor to a controller. A user-friendly interface helps to quickly configure the sensor settings. Measuring intervals can be defined and different limit values can be set according to the oil parameters. Another option allows you to graphically display the recorded measurement results. The trend shown in this way already provides information about the current status of the oil condition and can be used for early detection. All changes are logged.

Übersichtliche und benutzerfreundlicheClear and user-friendly user interface for reading out the sensor data.
