6512 – SONDE MOUNT KIT FOR 6820/6920 SONDES
The 6512 Sonde Mount Kit enables a 6820/6920 sonde to be deployed in a permanently mounted
three-inch schedule 40 PVC tube, not included in kit, approximately 10 feet in length. The tube
is mounted to 1-1½” diameter railing by included brackets and u-bolts. The sonde will be
deployed by gently sliding it down the tube
where it will rest on a Stop Cap at the end
of the tube. The probes and probe guard
will protrude through a hole in the stop cap
at the end of the tube.
The 6512 Kit should not be mounted on hot
or vibrating pipes or structures, or near a
high heat sources, AC motors or
transformers, radio transmitters or antennas.
Do not mount on electrical conduit.
Avoid routing the sonde cabling near wiring
associated with rotating machinery and/or
equipment involving electrical switching or
regulation. Consider placing sonde cables
in grounded metallic conduit if unstable
readings appear due to electromagnetic interference.
