7. Working Principle
Working principle of this sensor is based on the frequency sweep
technology. The sensor tip will send out electric field signal, and
different resonance frequency is created according to different
medium. Thus a switching signal will be triggered if the sensor is
covered with material..

10. Installation
Before installing and unloading the product, make sure that the device is
not suffered to any pressure and that the material inside the pipe or
container does not have leakage. Pay attention to the potential hazards
relevant to the temperature of the device and the media.
10.1 Installation Environment
Suggested to install the product in a metal container or pipe.
When installed in a plastic container, performance degradation or malfunction
may occur due to interference.
Check that the product is working properly via the field test function.
If interference occurs, take appropriate measures (shielding, grounding).
For pipe installation, the pipe size must be bigger than DN80.
Install the sensor at a distance of at least 30mm from the pipe wall, structural
parts, stirrer, and other sensors to prevent errors caused by collision or
interference (as shown below).
The insertion of the sensor should be sufficient to prevent the sediment from
being wrongly considered as the material. The probe of the sensor must be
completely through the tank wall.
Do not use seal tape. The sensor must be well grounded with the container
or pipe.
The sensor probe must be protected from direct sunlight (UV).

12
10.2 Installation process
Make sure that the sealing surface is clean before installation and remove the
protective cover only when installing. If the sealing surface is damaged, replace
the device.
The distance between the front probe and the silo wall has to be over 30mm in
order to prevent the sensibility to be influenced.
Install or weld the adapter sleeve onto the container/pipe.
For installation of the tri-clamp, follow the relevant provisions for additional
installation steps.
Attach the seal to the sensor through the thread lock sleeve. The seal must be
correctly positioned and locked. Close the gap between the sensor and the
adapter sleeve end face.
An inappropriate seal may cause installation errors.
- The seal is too large: It may be squeezed out, causing shear damage and
unable to seal.
- The seal is too thin: The seal is insufficiently compressed between the
sensor and the adapter sleeve. Leakage may occur.
Standard
Apply a little grease in the thread to help locking.
Lock the sensor into the adapter sleeve and tighten with a tightening torque
of 20...25 Nm.
After locking, the seal must not be exposed or cut off. It must be compressed
at least 1/4 wire diameter or more than 0.3mm to ensure sealing.

13
Rear install type
Auxiliary rod is needed for rear installation, auxiliary rod is not included in the
order (customized order if need)。
When tightening, the sealing ring is not exposed and must be compressed at
least 1/4 wire diameter or more than 0.3mm to ensure the seal, and the
tightening torque is controlled between 20...30 Nm.

10.3 Installation examples
The sensor can be installed as shown below:
Tank Diagram
The figure shows an example of container installation, such as for level
detection or as idling protection.
Note！
1. Mounting the probe at a 20°incline will can avoid material bridges from forming.
It also won't be damaged by the inflowing material.
2. For top-mounted installation, the rear-mounted type with the extension of the
auxiliary rod can be installed at a lower position (◆: the auxiliary rod is not
included in the order).
3. The rear-mounted auxiliary rod extends through the sediment can prevent from
severe bridging. (▼: auxiliary rod is not included in the order)

15
Rear install type
Top-mounted Side-mounted
After installation, please check whether the resistance of the container or
pipe entrance is within the allowable range.
Make sure that the top cable is properly sealed, such as installing and locking
the cable gland.
Cables cannot be routed directly upwards, please go around for a short
distance and then route them upwards to release water.
The probe crosses the material of
the barrel wall and effectively
inhibits bridging.
High/low alarm and to
solve the problem that
no hole in the side.

11. Wiring Instructions
Attention! Wiring must be carried out by an electrician.
Make sure you comply with national and international regulations related to
the installation of electrical equipment.
The input power supply must be within the specifications of the product.
Turn off the power before wiring.
Make connections according to the wiring diagram below.
Insert the connector plug into the top socket of the
sensor and tighten the nut.
For hexagon nuts, please use a 14mm open spanner to tighten
torque of 1~1.5 Nm(0.1~0.15 kgf.m).
Wiring diagram:
R1 and R2 represent the load of OUT1 and OUT2 respectively.
To protect the sensor from damage in the event of system failure, adding FUSE
0.2A to the power circuit is recommended.
only represents the property. The actual wire color depends on the connector
purchased.
Torque: 1.5Nm

11.1 Simulation output test
1. Finished the installation and supply the sensor with 12~30Vdc.
2. Lean a magnet close to the + sing for 3 seconds
or more, there will be switching output with
corresponding LED light display.
3. Remove the magnet from the + sign, the
switching output and corresponding LED light
display will return to normal status.
4. Magnetic(min 100GS@10mm)is in use.

12. Step of magnetic alignment/Calibration for sis sensor
(Figure 1) (Figure 2)
1. Under the power supply, take the magnet close to the hexagonal surface of the
sensor (Figure 1), an analog alarm will appear after 3 seconds, and the yellow
LED will turn on (Figure 2). Confirm that there is no abnormality in the induction,
and power off the sensor while not removing the magnet at this time.
2. Turn on the power again, and after about 3 seconds, remove the magnet, and the
yellow and green lights of the sensor will flash at an interval of every 2 seconds
(Figure 2).
It means the calibration can be proceeded from now.
3. The probe should not touch any material. Take the magnet close to the hexagonal
head surface again for staying one second, and remove the magnet. The yellow
and green lights will flash respectively for 1 second. At this time, the sensor will
record this status for not touching the materials.
4. Make the sensor touch the detected materials to measure, and have the magnet
close to the hexagon head again, stay for one second and then remove the
magnet. The yellow and green lights will flash at an interval of about 0.5 seconds.
At this time, the sensor will record the state of the detected material.
5. Take the sensor out of the materials (if material is attached ,no need to remove the
materials from the probe).
Have the magnet close to the hexagon head again, stay for 1 second, and remove
the magnet. Check if the green light flashes for 3 times, and calibration is
completed.

13. Daily Maintenance And Handling
Regularly check the probe for material accumulation or damage and clean as
needed. Replace the device if it is damaged.
Before removing and reinstalling the device, carefully clean the probe neck and
the mounting slot, especially the sealing cone. Take appropriate methods to
ensure that no external matter enters the device.
Attention! If the medium is changed, you need to change the sensor model.
The sensor is packaged on a one-time basis and cannot be repaired.
Follow local regulations when disposing of the device.
Before returning the product, make sure that the product is free of dirt, especially
dangerous or toxic substances.Appropriate packaging must be used to avoid damage
to the device.
