Model Number And Ordering Information
EXAMPLE: To specify the Model SDT Submersible Transmitter with 11-30V Input
and 4-20mAOutput, having to measure 15psi (34.6 Ft water), with a standard nut
and polyurethane cable & electrical connection, 316 stainless steel diaphragm,
silicone oil fill, Viton grommet and 100 feet of cable: SDTSB0015NLSV (100ft cable)
NOTES:
1) Cable Termination side should be located in a dry termperature
stable environment.
2) Damage will result if submerged in frozen liquid.
3) A fused or crrent limited DC power source is recommended
to prevent damage during fault conditions.
4) Shield is tied to case on EMI versions only
5) Additional pressure ranges are available, consult factory.

Model SDT Transmitter Installation
CAUTION: Remove power before installing or
servicing. To install the Model SDT Transmitter,
connect the surface end of the cable to the Ametek
Model DMC Meter Controller or other power source
and indicator. Suspend the transmitter into a well
or tank supported only by its attached shielded
electronic cable. Insure that the opening in the well
or tank cover is large enough for possible future
removal of the transmitter.
Additional support to the transmitter is available
with an optional factory installed cable support. The
optional cable support is recommended when using
longer lengths of cable or when suspending the
transmitter into agitated liquids. The cable support
provides strain relief for the excess stress found
under these circumstances. See diagram of Model
SDT Transmitter with cable support using customer
supplied and installed support cable.
CAUTION - The cable grommet and support are
specially installed by factory-trained personnel to
insure watertightness. Any adjustment or removal
of these items may destroy the watertight feature
thus exposing the transmitter to water seepage,
an electrical short and transmitter failure. Any
adjustment or removal of the cable grommet or
cable support voids the warranty.
CAUTION - Waterproof cable should not be kinked
or nicked, this would allow water into the electronics
housing. Permanent damage will result. (Never cut
or splice the waterproof cable). The surface end
of the cable is used as the system’s atmospheric
reference, this end should not be sealed. Vent to dry
temperature stable environment.
External surge or lightning protectors are available
as optional items and are strongly recommended
for increased protection from secondary surges
or lightning strikes. The units are easy to install,
are maintenance-free and respond in less than
one nanosecond. Install in accordance with the
instructions:
1. Lightning protection devices should be placed
as close to the instrument as possible and
wired in accordance with National Electric
Code in an approved watertight enclosure.
2. If the distance between the meter and transmitter,
or the meter and recorder is less than 100 feet,
only 1 protector per line may be used.
3. Use No. 10 AWG ground wire or better from
protector to earth ground.
4. Provide a separate ground for each run of
shielded cable or metal conduit.
5. Keep the ground wire less than 1 foot long
and tie to a suitable ground rod or metal frame
ground. Surge capability is only as good as
the grounding method. All ground connections
must be installed.
6. Install all protectors in weathertight enclosures.
7. Run signal lines shielded and away from power
lines.
8. Wire according to the Electrical Code.
9. When used for an intrinsically safe installation,
only one LMA912 should be installed in the haz-
ardous location. Do not substitute protector types.
Caution - This or any installation cannot protect
against a direct lightning strike, or secondary
strikes of sufficient magnitude. Ametek cannot
accept liability for damage due to lightning or
secondary surges.
