hazardous environments
The sensor must be installed with the exclusive “Thread adapter” and its sealing
ring to ensure proper sealing
The special requirement used in the dust-explosion environment
If the connection is the metal tank or pipe, it must be grounded so the danger of static
electricity generated by friction or impact can be avoided.
If the connection is not the metal tank or pipe, the sensor must be installed with the
exclusive “Thread adapter” and use “thread adapter” to complete the grounding.

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 DN25.
Install the sensor at a distance of at least 15mm 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 (especially solid materials). 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).
Warning !
In the dust explosion-proof environment, it is forbidden to produce the process of
propagation brush discharge type and brush discharge type. Such as the rapid
movement of dust particles, powder transfer process and spraying process in
electrostatic coating process.

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 or adapter sleeve.
Install or weld the adapter sleeve onto the container/pipe. For the welding
operation, please refer to "SISB Welding Adapter / Thread Adaptor Operating
Instructions".
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.
Use the seal supplied with the sensor only. An inappropriate seal may cause
installation errors.
- The seal is too thick:A gap exists between the sensor tip and the adapter
sleeve.
- The seal is too thin: The seal is insufficiently compressed between the
sensor and the adapter sleeve. Leakage may occur.
Normal type
The seal (supplied with the adapter sleeve) is
squeezed
The sealing cone of the adapter sleeve/the sealing
end face of the probe is squeezed
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.

16
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.

17
10.3 Installation Examples
The sensor can be installed as shown below:
Normal type
Tank Diagram Pipeline Diagram
The figure on the left shows an example of container installation, such as for
liquid level detection or as idling protection.
The figure on the right shows an example of pipe installation as liquid level
monitoring.
Attention! For highly viscous medium, the installation location ★in the
figure is only applicable to a certain extent. Residues may be incorrectly
detected as liquid level output.

18
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.
10.4 Grounding instructions for dust-explosion zone
To prevent dust or flow being generated by friction or impact, this product can
be used in the dust-explosion area. Please confirm the grounding condition in
the installation environment and take proper grounding.
If the connection is the metal tank or pipe, this product is grounded through
“thread adapter” and metal tank or pipe. Please confirm that the installation
environment is grounded to prevent electrostatic charge.
If the connection is not the metal tank or pipe, the sensor must be installed
with the exclusive “Thread adapter" and use “thread adapter” to complete the
grounding.
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.
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
0.5A to the power circuit is recommended.
only represents the property. The actual wire color depends on the connector
purchased.
Note: The accuracy and efficiency can not be guaranteed if using NON-FineTek
connector.

11.1 Simulation output test
1. Finished the installation and supply the sensor with 18~30Vdc.
2. Lean a magnet close to the + sing for 2 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.
11.2 M12 cable connector for dust-explosion zone
Do not open the connector when there is an explosive dust environment.
Please complete the M12 cable installation in the safety area first, and
then complete the on-site installation before providing supply power.
Please use 14mm size open-end wrench to operate with the torque around
1~1.5 Nm (0.1~0.15 kgf.m)..
Use M12 cable type in dust explosion-proof environment which approved by
