Nexisense OIL-408-S Online Water Oil Sensor Product Definition
The Nexisense OIL-408-S online water oil sensor is a high-precision device designed for monitoring oil content in water. It can real-time detect the concentration of dissolved oil in water, suitable for various industrial applications such as water treatment, petrochemicals, and environmental monitoring.
Working Principle
The OIL-408-S sensor utilizes fluorescence measurement technology. Its working principle is based on the fluorescence characteristics of dissolved oil when illuminated by light of a specific wavelength. When the sensor emits monochromatic light onto the dissolved oil in water, the oil absorbs the light energy and emits another wavelength of fluorescence. The sensor measures the intensity of the emitted fluorescence to determine the concentration of dissolved oil in the water, offering high sensitivity and fast response.
Structural Analysis
The OIL-408-S sensor features a compact design, making it easy to install and maintain. Its main components include:
Sensor Body: Made from 316L stainless steel, providing excellent corrosion resistance and high-temperature tolerance.
Light Source: Utilizes a high-stability UV LED light source, ensuring long service life and low drift.
Electrical Connection: Equipped with a 5-core shielded cable, supporting RS-485 and 4-20mA outputs for easy integration with other devices.
