ECD Turbidity Measurement Sensor

Designed with an innovative multi-beam optical sensor, highly intelligent electronics and self-cleaning technology, the new ECD Triton TR8 Turbidity Analyzer sets a new standard for precise, highly reliable water quality monitoring with virtually no maintenance.

The Triton TR8 TA’s sensor measures turbidity with a unique multi-beam optical assembly. The first light beam is a reference detector that compensates for changes in the LED light source caused by aging or other variables. The second light beam detects the short path length, which is best for high concentration measurement. The third light beam measures the longer path length, which is best for lower concentrations.

With its highly intelligent microprocessor-based design, the Triton TR8 TA’s sensor electronics constantly adjusts turbidity signal readings versus the reference detector for superior measurement accuracy. A built-in digital filter helps to suppress potentially interfering signals while self-monitoring diagnostics assure high reliability.

The Triton TR8 TA’s sensor assembly relies on a long-life near infrared LED light source (880 nm), and the 90-degree scattered light method in accordance with ISO 7027/EN 27027. The sensor is factory calibrated in formazine, FNU (Formazine Nephelometric Units), and is plug-and-play ready for applications. Two non-volatile memory banks are also available onboard to store user-initiated calibration data.

The highly accurate Triton TR8 TA operates over a wide measurement range with output in multiple units: 0.000 to 9999 FNU, or 0.00 to 3000 ppm, or 0.0 to 3.0 g/L, or 0 to 20%. The TR8 TA sensor features an error rate of less than 5% of reading with repeatability greater than 1% percent of reading.

The rugged Triton TR8 TA’s sensor assembly features an inclined face that is oriented into the liquid flow for optimum self-cleaning, which greatly reduces plant maintenance requirements to the occasional manual sensor swiping with a soft cloth. An optional automated mechanical wiper also is available for heavy-duty service environments or for difficult-to-reach sensor locations.

Developed for rugged water treatment environments, the tough Triton TR8 TA sensor is designed to operate at ambient temperatures from -5 to 50°C (20–120°F). It withstands pressures up to a maximum of 6 bar at 25°C and 1 bar at 50°C.

The TR8 TA’s controller digitally communicates with the turbidity sensor and provides a 4–20 mA output and alarm relay. The TR8 TA’s controller features ECD’s multi-bus architecture, with up to 4 inputs, 6 outputs and 8 SPDT relays. It includes a configurable local graphics display and HART protocol communication is available as well.

Accurate measurement of turbidity with the Triton TR8 TA is important in a wide range of surface water, municipal water and industrial water treatment applications. Turbidity is the cloudiness or haziness of a water sample, caused by suspended particles in the water that are typically clay and silt. Viruses and bacteria attach themselves to the particles and are a critical indicator of overall water quality.
