General Description

The CS511-L is a rugged, low-maintenance sensor that is manufactured by Sensorex. It 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 which produces a chemical reaction. An electrical current is produced by this reaction which is converted from microamps to millivolts by an in-line resistor. An in-line thermistor provides automatic temperature compensation.

Options

The PT4-L agitator is for applications where the water velocity is less than 1 inch per second (2.5 cm s^-1). The PT4-L agitator consists of 12 Vdc solenoid and toggle mechanism that sweep a brush across the probe membrane. A PFS timer controls the sweeping frequency to keep the probe clean and provide water movement for accurate readings.

Service kits are available for easy replacement of sensor components in the field; contact our office for details.
