1.1.7 Remote Mount Transmitter Head
For applications with possible clearance or transmitter accessibil-
ity issues, the JM4 is available with a remote mount transmitter
head. This transmitter head comes with a 3 or 12 ft (0.91 or
3.66 m) heavily shielded cable and can be mounted onto nearby
objects.
NOTE: Not available for Explosion proof units.
1.1.8 Hi-Temp Configurations and Temp Limits
The hi-temp JM4 transmitter is capable of operating in process
temperatures between -50 and +800 F (-46 to +427 C). Keep in
mind that the hi-temp JM4 has a neck extending 9 1/4” (23.5
cm) from the probe to the transmitter head (as opposed to 5
1/4” or 13.3 cm for the standard JM4), so height restrictions
should be considered before installing.
1.2 Mounting for External Mount
1.2.2 Available Configurations
The externally mounted Jupiter Model JM4 transmitter is
available with a variety of configurations and mounting options.
These include (in order from left to right in Figure 1-4) top-
mount, top-mount offset, bottom-mount offset. All of these
configurations are available with one or two magnetic floats (two
floats are necessary to measure total AND interface level).
1.2.3 Securing the Transmitter to the MLI
Each externally mounted JM4 transmitter is provided with a set
of clamps (2 or more, depending on probe length) for securing
to the MLI chamber. If the JM4 was ordered with an Orion
MLI, then it will come pre-mounted, but if the transmitter was
ordered separately, then it can be secured using the following
steps.
1. Place the Jupiter transmitter and mounting clamps in a conve-
nient location.
2. Position the Jupiter transmitter on the side of the MLI where
it will be attached. Mark the location and the exact area where
the clamps will be attached to hold the Jupiter in place. The
probe should extend above and below the process connections to
ensure full coverage of the desired measuring span.
3. Attach the lower clamp and tighten so that it remains in place,
but loose enough so that there is still room to place the guide tab
from the Jupiter between the inside of the clamp and the outer
diameter of the MLI chamber.
