A simple low cost oxygen monitoring system  or self assembly or inclusion in control panels

• 1 x oxygen probe per transmitter
• 2 x relay out-puts
• 1 x analogue out-put
• 1 x clip on display
• Din rail mount as many units as you like in an enclosure, supply power 24v to 230 v ac/dc

Oxygen probe manual, with calibration instructions when used with transmitters.   calibration & set-up

Dryden Aqua provide two types of transmitter for use with our oxygen probes. There is an option for a DIN rain mount transmitter or a panel mount transmitter.  By simply connecting the transmitter to our oxygen probes you have a complete oxygen monitoring and control systems, or you may simply use the analogue out-put from the transmitters to feed into your own PLC system.

The oxygen transmitter will accept an input directly from our Oxygen Probes.  If you want to display and alarm for both oxygen and temperature (PT100 sensors) then two transmitters will be required. The transmitter can be set up to give virtually any analogue out-put that you may want (e.g. 0 to 10v, 0 to 20mamps, or 4 to 20mamps).  There are also two programmable relay out-puts and a display.

DIN rail mounted transmitter |

you may mount one transmitter next to an oxygen probe for local monitoring and control, or you can locate the transmitter in the control room.  You may have up to 2000m of cable on one of our probes,  this is okay,  you do not need to locate the transmitter next to the probe.  This arrangement then allows you to fit a multiple number of transmitters in the one box, for example you may have up to a 100 transmitters in one enclosure, and then use the analogue out-put to feed into a PLC, computer or data logger.

The transmitters are provided with a clip on front display which is used to program the transmitter for different functions. The display gives the raw data out-put from the oxygen probe.  It is useful to display the raw data, especially if you are using PLC based systems. The display can also be used to calibrated the unit to display the data as dissolved oxygen  (units will be shown as mv).  This makes for a very low cost multi-channel dissolved oxygen monitor.
