Sensorex Dissolved Oxygen Sensors Support Continuous Submerged Water Applications

The DO6400 and DO6441 Process Dissolved Oxygen Sensors from Sensorex are submersible galvanic sensors available with either a built-in 4-20mA output signal capability for direct connection to a PLC or they can be connected to a standard 4-20mA transmitter and local display. The DO6400 and DO6441 Process Dissolved Oxygen Sensors can be used for long term continuous deployment in wastewater and aquaculture applications.

The low maintenance, dependable DO6400 and DO6441 Sensors feature reliable galvanic cell technology and a large volume electrolyte reservoir for long term continuous deployments. The 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 Dissolved Oxygen Sensor features a mV output (0.25-20 ppm) and the DO6441 Sensor offers a built-in 4-20mA 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.

The Model DO6441T Sensor now offers the user a factory calibrated 4-20mA output for direct PLC interface. If an external transmitter with local display is desired, the DO6400 Series is compatible with the Sensorex DO500 and DOMA 4-20mA loop powered transmitters. The transmitter display can be programmed to read percent saturation, mg/mL or ppm DO. Temperature is also visible on the display via a Pt100 temperature sensor (automatic) or manual input.
