level detection in a wide variety of process control appli­cations within the powder and bulk solids market. The vibrating probe principle overcomes application difficulties
ssociated with changes in material, temperature, and
a humidity while providing reliable solid state electronic cir­cuitry that requires no calibration.
VibraRod has the ability to detect a wide range of
The material densities. In addition, using a single-prong probe eliminates the potential problems associated with material build-up and false signaling associated with the dual­prong “tuning fork” probes.
VibraRod is available in a variety of configurations,
The each specifically designed to satisfy particular applica­tions. Available configurations include: standard probe and pipe extension probe.
PR IN CI PLE O F OP ER AT IO N
VibraRod™ line of point level sensors is a mechani-
The cal resonance system that is excited at a resonance by an electrical circuit. Two piezoelectric crystals are mounted internally at the probe’s base. The electronic module gen­erates an electrical signal that has an equivalent frequen­cy to the probe’s resonant frequency; this signal is applied to one crystal, which causes the probe to vibrate. The vibration is monitored by the second crystal which pro­vides an electrical signal back to the electronic module. When material contacts and surrounding the probe, the vibration is dampened and the signal from the second crystal is reduced. This signal reduction is detected by the electronic module, which reacts by providing a signal out of the module through the relay contacts.

Choosing a Location: (See Figure 1)
1) Material Flow: When selecting a location for the
VibraRod™ level sensor, choose a point in the vessel
where the probe will be out of the direct flow of incom­ ing and outgoing material to prevent any mechanical damage that may be caused by the pressure of the flow (See section regarding Protective Baffles). The
VibraRod sensor must be positioned at a point where
incoming material will reach and cover the probe in its normal flow, and when receding, will flow away from the probe in an even manner. Choose a position where a majority of the probe (not just the tip) will be covered. This is particularly important when detecting materials with low bulk densities. If the target material to be sensed is a powder, the
be installed at an incline exceeding the angle of repose (for high level detection use vertical mounting) in order to pre­vent powder buildup/clinging that might substantially reduce the self-cleaning effect of the vibrating rod. Also, avoid

recess (See Figure 2). In addition, material flow char­ acteristics such as “rat holing” (caving) or “bridging” (arching) of the material in the vessel should be con­ sidered.
2) Vessel Interference: Select an area where the probe will not come in contact with internal structures of the vessel.
3) Vibration: CAUTION
- The VibraRod should not be used in applications with severe vibration, such as being in close proximity to vibration devices used to promote material flow, as this could damage the probe.
4) Dynamic Material Flow: Please consider the maxi­ mum limits of bending force as shown in Figure 3 when choosing a mounting location and installing the
VibraRod level sensor.

Also, note that the sensor may not reliably trigger / alarm unless covered by a static layer of material. Constantly moving matter may present an issue.

The
VibraRod is a sensitive level sensing instrument.
Therefore, particular attention should be given to assure that the mechanical construction of the probe is not dam­aged by material. Probe deflection (bending) as little as 1/16” can render the probe inoperative. Failure to prop- erly protect the probe will invalidate the warranty. Install a protective baffle above side mounted probes. The baffle can be created using a number of materials
ncluding angle iron, welded plates and pipe sections. It
i should be securely mounted to the vessel wall and should extend the full length of the probe. The lowest part of the baffle should be 4” to 6” above the upper edge of the probe.

ME CH AN IC AL IN STA LL ATI ON
Because of their vibratory nature, sensors like the
VibraRod™ are sensitive industrial level sensing instru-
ments. Therefore, particular attention should be given to ensure that the mechanical construction of the probe is not damaged during and after the installation (See Figure
5). WARNING! Handle the great care, especially the sensing probe. Any impact on
VibraRod level sensor with
the sensing probe may result in damage to its resonance system.
robe Mounting: (See Figure 4)
P
1) Coupling Mount: Cut a hole into the vessel suitable for
a 1-1/4” NPT pipe coupling. Position a half-coupling as desired on the vessel and weld into place. Thread the
VibraRod into the coupling and tighten by rotating the
process connection. Pipe joint sealant or Teflon
®
tape may be used to achieve pressure-sealing capability if desired. WARNING! Never attempt to tighten the
rotating its housing! Do NOT use any type of “strap
VibraRod by
wrench”.
2) Housing Orientation: Once the VibraRod is securely mounted in the mounting coupling, rotate the housing approximately 360˚ maximum (by hand-only) to reach the desired cable outlet position.
3) Pipe Extension Installation: The
VibraRod pipe
extension configuration, when top mounted, is intended for high-level detection only. If side mounted, baffling is
advised and maximum pipe length is 24” (0.61m).
Pipe Extension Reinforcement: (See Figure 6) Mechanical reinforcement of the pipe extension should be considered whenever installing a probe length greater than 60” (1.5m). The pipe extension should be anchored to the sidewall with braces to reduce mechanical stress at the connection point of the extension and to protect the
VibraRod from damage. When bracing, never weld or
drill into the pipe extension since the electrical wires within the extension may be damaged. Use mechanical clamp­ing techniques.
Bracing and Haz-Loc Pipe Extensions:
The integrity of pipe extension model warrants extra consid­eration when installing. On either top mounting or side mounting, one must consider the potential for material side­loading forces that could put increased strain on the pipe at the connection point and then install mechanical bracing as appropriate. Top-mount pipe extensions over 60” (1.5m) or side-mount pipe extensions over 18” (0.46m) should be con­sidered for supplemental mechanical support.
PIPE EXTENSION REINFORCEMENT
Figure 5: Prevent mechanical damage.
Prior to installation, it is recommended that the VibraRod be tested for functionality on a sample of material (See Setup). The unit may not function with granular material where the particle size is large (1” [25 mm] diameter max­imum) even though the bulk density is within the specified density range due to the potentially small surface contact between the material and the probe.

Hazardous Location Precautions:
Observe the regulations listed in the NEC (USA) or CEC
Canada) regarding equipment in hazardous locations
( when installing the hazardous location models of the
VibraRod™ level sensor in hazardous classified loca-
ions. Wiring must be performed according to the authority
t having site jurisdiction and is the sole responsibility of the installer to ensure such.
It is important to note that the hazardous location mod­els are certified with two protection concepts: The probes and wires from them to the enclosure is an intrinsically­safe circuit but is still Haz-Live. The enclosure and elec­tronics within are not intrinsically-safe and protection is by dust-ignition proof enclosure.
Factory Wiring:
The probe wires internal to the housing are connected to the frontside of the PCB. DO NOT alter this connection. Doing so will likely cause improper operation of the sensor and likely per­manent damage. (See Figure 7)
Permanently Connected Equipment: Disconnecting devices shall be included in the system installation. In installations where multiple circuits are used (i.e. independent circuits for power input and relay output), individual disconnects are required. The discon­nects shall be within close proximity of the equipment, accessible to operators, and marked appropriately as the disconnect for the associated circuit. Assure the discon­nect ratings are appropriately sized to the circuit protected (See Specifications). The MAINS power that connects to the sensor MUST provide circuit protection and NOT exceed 30A total.
Circuit Separation (Standard version only): Two cable entry locations are provided to aid in maintain­ing separation of “hazardous live” (typically mains volt­ages such as 115VAC and 230VAC) and limited circuits (typically control voltages less than 30Vrms or 42.5VDC). However, since the partment can not absolutely protect against physical con­tact between multiple circuits, it is required that all wiring used must have an insulation rating of 300V minimum, and a temperature rating of 176˚ F (80˚ C) minimum.
Protective Earthing:
VibraRod level sensor is provided with a “protective
Each conductor terminal” which shall be terminated to the local earth ground potential of the facility to eliminate shock hazard in the unlikely event of internal insulation break­down. Select wire size that can carry in excess of the sum of all circuits maximum amperage.
1) Remove the housing cover to access the terminal
blocks and operating mode switches. All wires must be routed through the conduit openings.
2) Power Input: (See Figure 7) The
provided with a HI / LOW voltage, AC/DC universal power supply. If using a DC power supply, polarity is irrelevant.
3) Do not remove the green wire from J1 MAINS terminal
because it is an internal connection. For grounding the unit, either use the grounding screw terminal on the outside of the housing or use the internal grounding screw terminal on the circuit board (J1 MAINS). The earth ground screw should be connected to a quality "ground" to eliminate shock hazard.

4) Output Contact Connections: The SPDT relay con-
tacts can be used to indicate whether or not material is being detected by the sensor within the vessel. These outputs are also influenced by the setting of the Fail­ Safe switch (See Setup). The output contact(s) can be used to switch high voltage/high current loads as listed in the Specifications. Whenever possible, use an independent voltage source to operate the loads. Select wire size that can deliver suitable voltage and current for the application. Follow all electrical codes and use proper wire gauge size. Tighten cable glands as well as housing cover after installation to ensure proper sealing for “Type 4X” environmental protection.
Conduit Entries: Conduit entry threads should be lubricated with a material such as lithium grease to ensure water ingress protection required to maintain the Enclosure “Type 4X” rating.

Complete set-up of the VibraRod™ is accomplished sim- ply by adjusting the sensitivity and fail-safe settings. Each application can be adjusted independently for optimum operation.
Material Density:
The SENSITIVITY selector should be set in accordance with the density of the target material:
Position A
10.0~12.5Lbs/Ft loose and light materials, greatest sensitivity of detection.
Position B, medium sensitivity position: For materials with density 12.5~15.6Lbs/ft for modest density materials.
Position C, low sensitivity position: For materials with den­sity 18.7~21.8Lbs/ft thick and heavy materials, least sensitivity of detection.
If the material to be sensed can potentially form heavy deposits on the probe, selection "LOW sensitivity" (Position “C”) should be chosen. This will provide addi­tional immunity to product buildup while still enabling the circuit to sense the presence of material.

Fail-Safe (Selector "J4" in Figure 7): Selection of the fail-safe mode (See Table 1) will permit the output contacts to be triggered in a manner that assures proper control of loads in the event of power fail­ure. To obtain fail-safe operation, use the relaxed output as an alarm, thus a power failure will also be considered as an alarm. Depending on which condition is most criti­cal to signal (high level or low level), the selection can be made by positioning the switch to one of the following:
FAIL-SAFE “HIGH” Position present, the relay will be energized. The relay will be relaxed when material is sensed, or if power failure occurs.
FAIL-SAFE “LOW” Position the relay will be energized. The relay will de-energize when no material is sensed, or if power failure occurs.

PROBLEM: Sensor will not sense material.
CAUSE/SOLUTION:
1) Verify power is applied to the sensor.
2) Verify sensor status by observing LED’s:
GREEN = not sensed, RED = sense, no light = no power.
3) Verify sensitivity setting. Position sensitivity selection in position Highest Sensitivity “A” thereby making the probe more sensitive to “difficult to sense” materials.
4) Verify probe coverage when sensing is expected. The sensor is not designed to be “tip sensitive”. Permit significant probe coverage before expecting material sensing.
5) Verify electrical connections.
PROBLEM: Sensor remains in “DETECT” mode even
when material is absent.
CAUSE/SOLUTION:
1) Verify sensor status by observing LED’s:
GREEN = not sensed, RED = sense, no light = no power.
2) Verify the probe is not in direct contact with any inter­ nal vessel structure. If so, reposition sensor.
3) Verify sensitivity setting. Position sensitivity selection in position Lowest Sensitivity “C” therefore making the probe less sensitive to “easy to sense” materials and more immune to material buildup.
4) Ensure there is no material buildup on probe. Product buildup across the probe surface or between the probe and vessel wall may create false detection. Clean probe if necessary.
PROBLEM: Output contacts perform opposite of
designations (N/O, N/C).
CAUSE/SOLUTION:
1) Check Table 1 for correct fail-safe switch selection.
Swap wire terminations of N/O and N/C if necessary. Changing the fail-safe selection is not recommend­ ed unless fail-safe feature is not a concern to the application.
