ECD OIW80 oil-in-water analyser

Click2Contact

Designed for demanding and/or dirty plant environments, ECD’s OIW80 oil-in-water analyser’s rugged sensor features a built-in wiper cleaning system to remove biosolids and films that might cloud the sensor window’s visibility. The sensor features a built-in automatic screen window wiper, to reduce technician manual checks and the frequency of scheduled maintenance cleanings.

The intelligent analyser is designed to precisely measure oil over a wide range of 0 to 30 ppm (mg/L) and can be factory preconfigured to measure oil in multiple ranges or easily set in the field. The rugged, high-performance analyser’s responsive sensor operates over a broad temperature range from 5 to 45°C to quickly detect leaks and alert plant technicians.

The heavy-duty construction of the OIW80 sensor’s rugged housing utilises strong, corrosion-resistant stainless steel (standard) or optional titanium, and meets the IP68 water ingress standard. Every aspect of the sensor’s design has been tailored for years of operation and trouble-free service in the demanding wet environments typical of industrial and municipal water and wastewater treatment applications.

The sensor utilises state-of-the-art fluorescence sensing technology for measurement of oil in water, which is typically proportional to its concentration. The sensor communicates directly with ECD’s versatile T80 universal transmitter when oil is detected.

During installation, the OIW80 system is connected to the intelligent ECD T80 transmitter and the sensor’s calibration range information is automatically uploaded to the analyser. It then automatically configures the displays and outputs of the transmitter to the values appropriate to the oil sensor’s measurement parameters.

Transmitters are available as either single- or dual-channel devices, allowing one analyser to measure up to two parameters or two ranges. The transmitter is available in a 24 VDC or a 100/240 VAC power configuration. All versions are available with an optional HART output to support integration with larger control systems.
