Model 4528 Detector – Types A, B, and C
The Model 4528 Detector mounts in the explosion proof conduit on the capacitance
probe. It converts water changes in the oil flowing through the probe to an output volt-
age that varies with the water.
The output will be 0-5 volts regardless of the range of the detector (i.e. 0-5%, 0-10%,
0-20%). To mount the detector in the condulet the top aluminum plate must be removed.
This can be accomplished by removing the three screws marked “A” in the above draw-
ing and gently lifting the top plate off of the printed circuit board. Find the short white
or red wire with the clip on it and gently pull the wire straight up. Remove the nut from
screw “B”. Insert the printed circuit board into the condulet. Position the board so the
rod sticking up from the probe goes into the round hole on the printed circuit board,
just below the “Probe” - “Ref” Switch. Center the P.C. Card over the mounting holes
and insert screw “B”. Push the clip on the end of the white or red wire down firmly on
the rod coming up from the probe. Rotate the clip if necessary. Replace aluminum top
