This sensor consists of a self-polarizing galvanic cell that generates a millivolt signal proportional to the amount of oxygen present in the measured medium (typically water). Oxygen diffuses through its membrane onto a cathode that produces a chemical reaction. An electrical current is produced by this reaction that is converted from microamps to millivolts by an in- line resistor. Benefits/Features The CS512 provides the following advantages over the older dissolved oxygen sensors:
- No gas buildup in the probe preventing blown membranes
- Completely sealed case (i.e., no vent hole)
- Plastic-to-plastic seal (i.e., no o-ring)
- Improved long term stability Specifications Range: 0 to 50 mg l-1 dissolved oxygen, 0 to 100% volume gaseous oxygen Output: 2.5 to 5 mV per mg l-1 Output impedance: ~1 kohm Repeatability: better than 0.2 mg l-1 Response Time: After equilibrium, 1 minute for 95% of final value Minimum water velocity: 1 cm s -1 across membrane Minimum submersion depth: 6.35 cm Operating temperature range: 0° to 40°C Pressure: 0 to 2 bar Temperature Compensation: Self compensating Dimensions: diameter: 5.8 cm, height: 5.9 cm Weight: 0.45 g Datalogger compatibility: CR200 series, CR510, CR10X, CR1000, CR23X, CR5000, CR7, CR9000(X); call for compatibility with older dataloggers
