Sensorex DO6400 and DO6441 process dissolved oxygen sensors

The DO6400 and DO6441 process dissolved oxygen sensors from Sensorex are fast-response submersible galvanic sensors available with either a built-in 4-20 mA output signal capability for direct connection to a PLC or to a standard 4-20 mA transmitter and local display.

The DO6400 and DO6441 are suitable for long-term continuous deployment in wastewater and aquaculture applications. Their galvanic sensor construction and electronics combine performance, ease of use and low maintenance to offer a reliable low life-cycle cost instrument for use in submerged water applications.

The low maintenance sensors feature reliable galvanic cell technology and a large-volume electrolyte reservoir for long-term continuous deployments. The easily replaceable membrane is available in either durable Teflon or wide-span HDPE membrane for faster response. An optional integral temperature sensor is also available for both models.

The DO6400 features a mV output (0.25-20 ppm) and the DO6441 offers a built-in 4-20 mA output (0-100% and 0-200%). The DO6400 series sensors are designed for easy installation and maintenance with a positive fit and easy-to-grip body design. They feature a Noryl body with silver cathode and operate at temperatures up to 50°C.

If an external transmitter with local display is required, the DO6400 series is compatible with the Sensorex DO500 and DOMA 4-20 mA loop-powered transmitters. The transmitter display can be programmed to read per cent saturation, mg/mL or ppm DO. Temperature is also visible on the display via a Pt100 temperature sensor (automatic) or manual input.
