Campbell Scientific CS512 Oxyguard Type III Dissolved Oxygen Probe

FIGURE 4-2. CS512 with PT4 Agitator

Optional Repeat Cycle Timer for Agitators: Reciprocating action may be controlled by the optional solid state Repeat Cycle Timer. It sends 12 VDC pulses to the agitator coil. The ON-time is 0.25 sec. The OFF-time is adjustable from 3 to 12 sec.; requires supply voltage 10 to 17 VDC; housed in watertight cylinder 6.6" x 2" diameter (170 mm X 50 mm).

5. Application Information

NOTE SCWin users: This manual was written primarily for those whose needs are not met by SCWin. Your procedure is much simpler: just add the CS512 probe (it’s in the water folder), save your program, and follow the wiring shown in Step 2 of SCWIN.

6. Wiring

The CS512 probe can use one differential channel or one single-ended channel.

Differential wiring is better at rejecting electrical noise and ground loop error.
