The Triton TR8 turbidity analyser, from Electro-Chemical Devices, provides water quality monitoring using a multi-beam optical sensor, intelligent electronics and self-cleaning technology.

The Triton TR8 TA’s sensor measures turbidity with a multi-beam optical assembly.

The first light beam is a reference detector that compensates for changes in the LED light source caused by ageing 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 intelligent microprocessor-based design, the Triton TR8 TA’s sensor electronics constantly adjusts turbidity signal readings versus the reference detector for measurement accuracy.

A built-in digital filter helps to suppress potentially interfering signals while self-monitoring diagnostics assure reliability.

The Triton TR8 TA’s sensor assembly relies on a long-life near infrared LED light source (880nm), and the 90deg 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.

Two non-volatile memory banks are available onboard to store user-initiated calibration data.

The Triton TR8 TA operates over wide measurement range with output available in multiple units: 0.000 to 9999 FNU, or 0.00 to 3,000ppm, or 0.0 to 3.0g/l, or 0 to 20 per cent.

The TR8 TA sensor features an error rate of less than five per cent of reading with repeatability greater than one per cent 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 is also 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 50C (20-120F).

It withstands pressures up to a maximum of 6 bar at 25C and 1 bar at 50C.

The TR8 TA’s transmitter digitally communicates with the turbidity sensor and provides a 4-20mA output and alarm relay.

The TR8 TA’s controller features ECD’s multi-bus architecture, with up to two outputs and four SPDT relays.

It includes a configurable display and Hart protocol communication is also available.

The turbidity sensor can be located up to 200m away from the controller.

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.
