3 Oxygen transmitter dTRANS O2 01
3.1 Application
General The instrument is suitable for continuous measurement of dissolved oxygen in
water.
Typical areas of
application - Measurement of the O
2
content in activation basins. The measurement
signal is used here for monitoring, and as a control parameter.
- Check of the O
2
content in the outlet of wastewater-treatment plants.
- Measurement and control of the O
2
content in fish ponds and fish farms
(fresh and salt water).
- Monitoring of public water, e.g. rivers, lakes, reservoirs etc.
- O
2
enrichment of drinking water.
3.2 Construction
of the
dTRANS O2 01
The oxygen transmitter consists of
- the housing (1) with the transmitter electronics and the connecting cable (2)
- the sensor module (3) and the protection basket (4)
(optionally with additional protective film)
of the
measuring cell The measuring cell for dissolved oxygen is a membrane-covered galvanic cell
with an alkaline electrolyte.
The cell consists of
- the cell body with the two connection contacts to the evaluation unit
- the silver cathode
- the lead anode
- the electrolyte
- the oxygen-permeable (but not porous) Teflon membrane, which
constitutes the boundary surface between the inside of the cell and the
sample liquid.
