CS510 OxyGuard Dissolved Oxygen Probe

FIGURE 5-1. Preventing Bio-fouling of the CS510-L

The PT4 Agitator overcomes these problems. The device is designed so that a soft

bristle brush sweeps across the probe membrane or sensor tip. This sweeping

action of the brush provides the required water velocity as well as prevents the

membrane from becoming bio-fouled.

The optimum sweeping frequency depends upon the design of probe and type of

membrane used and water conditions. An ON-time of 0.25 seconds and OFF-time

of 5 seconds is suitable in most circumstances.

Agitator’s overall size: 7-1/8" x 3-1/4" diameter, 1-1/4 lb. (180mm x 83mm, 0.6 kg)

Supplied with 10 ft. (3 meters) cable.

Power required: 10.5 to 18 VDC at the agitator, 1.1 amps. Maximum ON-time is

3 seconds.
