12 - 24VDC Hydrocarbon Sensor For Exhaust Gas Wash Water Monitoring

Hydrocarbon Sensor for Exhaust Gas Wash Water Monitoring

The measuring principle is based on the fluorescent properties of PAHs. Mineral oils rich in aromatic content will fluoresce when illuminated with ultraviolet light. The intensity of this fluorescence depends on the polyaromatic hydrocarbon (PAH) content of the oil. Typical oils that fluoresce include fuel oil, crude oil, hydraulic oil, and transformer oil. Each oil has its unique fluorescence intensity resulting from its specific PAH content. PAHs are integral parts of most mineral oil products and are a very specific indicator of oil contamination in water bodies and process water.

Product Introduction

Desun Uniwill PAH Measurement Sensors, designed for detecting Polycyclic Aromatic Hydrocarbons, is a cutting-edge device revolutionizing environmental monitoring. PAHs are organic pollutants with diverse sources, emphasizing the critical need for real-time monitoring to control pollution and assess associated risks effectively.

Desun Uniwill Online PAHs (Polycyclic Aromatic Hydrocarbons) Sensor works in the measuring principle of UV fluorescence, it’s more sensitive and specific than the conventional infrared scattering or absorption methods. This makes it possible to determine the smallest traces of PAHs, e.g. in drinking water, but also in cooling water condensates. It has an RS-485 interface that allows easy and fast sensor configuration via Modbus.

There are two measurement modes to choose from:

1. Analyzer mode,

Combine the instrument with a flow-through tank to lead the liquid into the glass tube for measurement.

2. Probe mode,

Online measurement of PAH (oil) content in water by UV fluorescence method with fast response and high sensitivity.

No need for sampling and sample preparation, no reagents.

Can be connected to supporting instrumentation, and can achieve 4-20mA analog output, to achieve a variety of control methods.

The field of application ranges from petrochemistry, and leakage detection in cooling and wastewater streams to environmental monitoring.
