Sensorex Introduces Two Process Dissolved Oxygen Sensors

Sensorex has added to its range of dissolved oxygen sensors with the DO6441 and DO6400 Process Dissolved Oxygen (DO) Sensors. These are submersible galvanic sensors offering fast response time and are available in two options, viz., with connectivity to a local display and a standard 4-20mA transmitter or with an inbuilt output signal of 4-20mA to connect directly with a PLC.

SX - DO Sensors

The process dissolved oxygen sensors DO6400 and DO6441 have been developed for long term submerged use in aquaculture and wastewater applications. The electronics and construction of the sensor offers a low and reliable life-cycle cost device and are easy to use.

The two DO sensors are designed to determine the quantity of dissolved oxygen in the wastewater and water. It is essential to maintain an optimal amount of dissolved oxygen in water treatment facilities since the process uses aerobic bacteria that can breakdown the organic compounds present in sewage. If the amount of dissolved oxygen is insufficient, the bacteria die and the wastewater treatment does not function efficiently and leads to septic conditions. It is also essential to accurately measure the dissolved oxygen content for aquaculture operations to ensure that the cultivated organisms have access to oxygen to flourish. If the content is low, the growth of organism is suppressed along with the reduction in fish feeding. Extremely low levels can cause stress in the fish and also lead to their death.

The DO6441 and DO6400 sensors feature an electrolyte reservoir of a large volume and a galvanic cell technology so they can be deployed for extended periods. Both the models are available with an integral temperature sensor.
