Internal electronics
All transmitters come with two electronic components of a sensing
element and a board set. Rigid sensing elements are standard on
CHAMBERED. The board set consists of up to three electronic boards
and a display.
A temperature sensing function is optional with the CHAMBERED
transmitter. The temperature sensing device is a Digital Thermometer
mounted inside the transmitter’s outer pipe assembly. The
CHAMBERED can be ordered with 1, 5, 12, or 16 temperature points.
Display
All LP-Series liquid level transmitters are shipped with a stylus (
Part # 404108) to be used for manipulating the display. For single and
dual cavity housings, the stylus is designed to allow for programming
of the unit without removing the housing. When using the stylus make
sure to align the stylus with the shape outline around the buttons in
the same orientation. Failure to correctly align the stylus can cause the
display to not function properly. Password for entering the menu is
27513. For additional details consult the protocol specific Modbus
Interface Manual (Part #551700), DDA Interface Manual (Part
#551701), and HART®Interface Manual (Part #551702).
Fig. 5: Stylus (Part # 404108)
Accessories
Temposonics also offers a series of displays, housings, converters,
and other accessories, please refer to the ‘Accessories Catalog’,
(Part#551103).
Fig. 6: Display
5.2 Accuracy
For magnetostrictive transmitters inherent accuracy is measured
in terms of non-linearity. Non-linearity is a measurement of any
imperfections in the waveguide that are reflected in the linearity of
the transmitter’s output. Temposonics tolerances reflect a maximum
non-linearity of ±1mm. Temposonics is able to achieve such strict
tolerances by manufacturing all of its own waveguide from a
proprietary alloy and testing 100% of all transmitters before shipping.
5.3 Warranty
Important:
Contact Technical Support or Customer Service for assistance if
you suspect that the transmitter is not working correctly. Technical
support can assist you with troubleshooting, part replacement, and
Returned Material Authorization (RMA) information if required.
All Level Plus®transmitters come with a two year limited warranty
from the factory shipment date. An additional extended warranty can
be purchased. A Return Materials Authorization (RMA) number is
required and must accompany any transmitter returns. Any unit that
was used in a process must be properly cleaned in accordance with
OSHA standards, before it is returned to the factory. A Material Safety
Data Sheet (MSDS) must also accompany the transmitter that was
used in any process.
5.4 Storage
If storage is required prior to installation, store indoors in a dry
environment at ambient temperature range not to exceed −40…+71°C
(−40…+160°F).

7. Electrical connections
7.1 Basic information
A typical intrinsically safe connection for the Level Plus®CHAMBERED
transmitter includes protective safety barriers, a power supply and a
reading or monitoring device. Refer to Agency information in chapter
13.
A typical Explosion proof/flameproof connection for the Level Plus®
CHAMBERED transmitter includes a power supply and a reading or
monitoring device. All cabling is in approved conduit with sealoffs
as specified by local electrical code. Refer to agency information in
chapter 13.
7.2 Safety recommendations
Be sure to:
1. Always follow applicable local and national electrical codes and
observe polarity when making electrical connections.
2. Never make electrical connections to the CHAMBERED transmitter
with power turned on.
3. Make sure that no wire strands are loose or sticking out of
the terminal block connection which could short and cause a
problem.
4. Make sure that no wire strands, including shield, are in contact
with the electronic module enclosure.
5. The electronics module enclosure is grounded through internal
circuitry and is electrically isolated from the explosion proof
housing.
7.3 Industrial topologies
There are four topologies described and illustrated below. However,
the daisy chain topology is not recommended by Temposonics.
Point-to-point
The point-to-point topology consists of having only one device on the
loop as shown in Fig. 9. This topology is not usually used with a bus
network since it does not take advantage of placing multiple devices
on a loop.
PLC
Fig. 8: CHAMBERED mounting, top and bottom flange
Bus with spurs
The bus with spurs topology has a main trunk cable that has each
device connected via its own spur at a junction box as shown in Fig.
10. The bus with spurs and tree topologies can also be used together
to form a hybrid topology.
Fig. 9: Point-to-point topology
PLC

Level Plus® CHAMBERED
Operation Manual
I14 I
Tree alignment
The tree topology is very similar to the bus with spurs topology with
the main difference of having a common junction box for all of the
transmitters as shown in Fig. 11. Bus with spurs and tree topologies
can also be used together to form a hybrid topology.
Fig. 11: Tree topology
PLC
Daisy chain
The daisy-chain topology utilizes a single cable that is connected to
all of the transmitters with the cable being interconnected at each field
device. When using this topology make sure that the wiring practice
allows for one transmitter to be disconnected without disconnecting
the entire loop as shown in Fig. 12. Temposonics does not suggest
using the daisy-chain topology.

7.6 Grounding
7.6.1 Safety grounding
Warning:
Grounding the transmitter through a threaded conduit connection
does not meet the requirements as a grounding of the sensor for
safety.
There are two methods to provide an earth ground connection to
the earth ground of the electronics. Either method must result in
a resistance of less than 1 Ω. Refer to ’Table 3’ for safety barrier
references.
• Run an earth ground through the conduit and connect directly to the
earth ground lug inside the housing.
• Run an earth ground directly to the ground lug on the outside of the
housing.
7.6.2 Shield grounding
Warning:
The shield ground does not meet the requirements as grounding of
the sensor for safety.
Immunity performance of the sensor from external sources of
surge, burst, RF, radiated emissions and other noise is dependent
on a proper ground for the shield of the communications cable.
The communications cable shield should be of a braided type and
connected to the internal ground lug of the sensor housing.
Runs in a continuous metallic conduit
When installed inside a dedicated continuous metallic conduit,
the conduit provides a level of shielding protection from external
interference and a level of ground to the sensor housing. In this case
a foil type shielded cable with a drain wire connected to the internal
ground lug may be sufficient. Sharing of the metallic conduit with
other cables will result in loss of effective shielding performance of
the communication cable and possible degradation in performance
of the sensor. In this case a braided type shielded cable connected to
the sensor internal ground lug would be recommended. In all cases
paralleling the communications cable with any noise generating cable
inside of a conduit or with noise generating cables in close proximity
to the conduit may degrade the performance of the sensor.
Runs without a conduit
In some rare applications, or where safety may not be required, a
metallic conduit may not exist. The communications cable shield
should be of a braided type and connected to the internal ground lug
of the sensor housing. Alternatively a safety approved EMC Cable
Gland can be used for grounding the shield. Contact Temposonics for
information before using one of these cable glands.
NEC
Undesirable currents (ground loops) is a violation of the NEC and is a
safety hazard.

13.3.1.1 Specific Conditions of Safe Use
1. When EPL Ga or Da is required, parts of the equipment containing
light metals (Aluminum or Titanium) shall be protected from
impact so that impact or friction sparks cannot occur, taking into
account rare malfunction. Measures to prevent impact or friction
sparks when using the equipment containing light metals include
but are not limited to
• Mounting the probe vertically
• No mechanical agitation shall be used
• Use of stilling wells to mitigate effect of agitation.
• Limit rate of change of level to values such that friction sparks
cannot occur
2. The maximum permitted ambient temperature of the Level Plus
Digital/Analog Level Transmitter is 71 °C. To avoid the effects of
process temperature and other thermal effects care shall be taken
to ensure the surrounding ambient and the ambient inside the
transmitter housing does not exceed 71°C
3. Warning: The equipment contains non-metallic enclosure and
process parts. To prevent the risk of electrostatic sparking, the
non-metallic surface should only be cleaned with a damp cloth.
Painted surface of the equipment may store electrostatic charge
and become a source of ignition in applications with a low relative
humidity <~30% relative humidity where the painted surface is
relatively free of surface contamination such as dirt, dust or oil.
Cleaning of the painted surface should only be done with a damp
cloth.
4. The applicable temperature class, process temperature range and
ambient temperature range of the equipment is as follows;
• T3 with Process Temperature Range of -40°C to 150°C
• T4 with Process Temperature Range of -40°C to 135°C
• T5 with Process Temperature Range of -40°C to 100°C
• T6 with Process Temperature Range of -40°C to 85°C
• Ambient Temperature Range -40°C < Ta < 71°C
