Installation
The control point for liquid level is the point at which the liquid makes
or breaks contact with the probe tip and is determined by the length of
the probe rod. Rods may be ordered to size, or may be supplied longer
than required and cut to the desired length. One end of the rod is
threaded for connection to the probe fitting. The unthreaded (cut) end
should be inserted in the probe tip and held by means of a set screw.
For deep well and other long probe applications over 10 ft (3 m),
suspension wires and tips should be installed. Standard probe tip
61­3288, is used with all probe rods. Special probe tip 61--3284 with
insulating sleeve, is used with suspension wire.
The probe rod or suspension wire adaptor 61--3285 is connected to the
probe fitting as follows:
61 Series fittings have a 1/4--20 female thread to receive the 1/4--20 male
thread of the probe rod or suspension wire adaptor.
When the long probe of any multiple probe assembly is over 30 in.
(0.76 m), a Teflon insulating spacer 31--224, is fitted over the short probe
rod immediately above the probe tip to prevent the rods from touching.
For suspension wire assemblies, an insulating sleeve fits over the probe
tip to prevent it from touching other surfaces.
Series 63 sanitary probes for dairy and food industry applications are
made for special sanitary fittings. The probe insulator is made to fit a #15
union ferrule and to be secured with a #13H union nut. The ferrule and
nut are supplied by the customer and are soldered, brazed, or otherwise
secured before insertion of the probe assembly. Probes 63GH1 and 63GH2
fit 1--1/2 in. ferrule, while probes 63GJ1 and 63GJ2 fit a 2 in. ferrule. All
Series 63 probe rods are 3 ft (0.91 m) long and are to be cut to length on
the job.
Mounting
The 13DJ3 controls may be mounted in any position on a sturdy wall,
partition, panel board, bracket, or similar support. While the NEMA
enclosure is being mounted, the control base should be stored in a safe
place to avoid moisture and mechanical damage.
The enclosure mounting hole dimensions are shown on page 12 and
sheet metal, wood or machine screws, bolts, or similar fasteners may be
used. When the housing has been securely fastened, connect the cables or
conduits to the housing in the knock out holes provided and replace the
control base.
The wiring between the control and the probes should not exceed the
lengths listed below.
