4. Principles
4.1 Product Principles
The guided wave radar emits a high-frequency pulse wave to be transmitted along with the
detection component (steel rope or connecting rod). When it comes in contact with the
object to be measured, the pulse wave will be reflected and some of the energy will be
reflected as well due to the different dielectric constant of air and the material. The time
difference between the reflection wave and the emission wave can be used to calculate
the distance between the surface of the measured object and the guided wave radar level
sensor.
4.2 Bottom Tracking Probe Technology
4.2.1 Bottom Tracking Probe Technology
The product is equipped with a bottom tracking probe technology. This function is very
useful in increasing the sensitivity when the dielectric constant of the measured object is
low, such as the plastic particles, material fragments or that in the liquefaction container.
When the dielectric constant is 3~10, the bottom tracking probe function will be enabled
automatically as long as the echo signal is not detected. The measurement value is
calculated based on the dielectric constant recorded the last time. In this case, the
instrument accuracy depends on the stability of the dielectric constant.
If the dielectric constant of the media is lower than 3, the bottom tracking probe function
will be enabled all the time. Under this circumstance, you must input the dielectric constant
of the media, which is quite important for measurement.

4.2.2 Function Principle –Dual-Level Interface Measurement
The high-frequency micro wave pulse travels along the steel rope or the connecting rod.
When it reaches the media surface, a part of the micro wave pulse will be reflected.
Another part will penetrate the media in the upper layer (L1), and the second reflection will
take place on the interface between the upper (L2) and lower (L1) interface layers. The two
periods of pulse running will be calculated by the PCB inside the instrument, which also
outputs two levels.
※Measurement condition of dual-level interface:
Media on the upper layer (L2):
L2 must be non-conducting media. The dielectric constant of the media in L2 or the actual
distance towards the interface is known. The dielectric constant of the media in L2 must be
larger than 1.6. The media must be stable without change or mixture. Moreover, it must be
uniform. The minimum thickness of the media in L2 should be larger than 50mm
(1.97-inch), and L2 must be clearly separated from the lower layer (L1). In case of
emulsion phase or chipping layer, the maximum thickness should be 50mm (1.97-inch). It
should be without foam on the surface if possible, so it will get better measurement results.
Media on lower layer (L1):
The dielectric constant of L1 must be 10 larger than that of L2 at minimum, and the
conducting media is recommended. For example, if the dielectric constant of L2 is 2, the
dielectric constant of L1 should be 12 at least.
Gas layer (L3): It is the mixture of air or gas.
Output signal setting of dual-level interface measurement:
This instrument requires applying the setting in “level measurement”, which should be
applied in dual-level interface measurement. You may select dual-analog output version
and adjust the settings.

7.2 Installation Instruction
7.2.1 Installation Site
Pay attention to the following when installing JTR3 series products. When it is installed in a
metal container, the distance between the container parts and the inner wall should be at
least over 300mm. For non-metal containers, the distance to the inner wall should be at
least over 500mm. During the operation, make sure the sensor doesn’t get into contact
with any device or tank wall. When using the sensor of a steel rope, it is recommended
fixing the sensor bottom in the tank to reduce the vibration to the sensor. For the tanks with
core shape at the lower part, it is recommended installing the product in the center of the
container to measure the lowest point at the bottom.
※Please note the upper/lower blind area of the instrument. It can’t measure the lowest point of
the sensor.
Note! When welding is required for the installation, please remove the electronic module of
the sensor from the junction box before welding. It can prevent the damage on the
electronic device due to the inductive coupling or other abnormalities.
Plastic container/glass container
The measuring principle of guided wave radar requires a metal plane at the process junction
point. Therefore, when it is used in the plastic container, it requires an instrument with flange
(since DN 50) or a metal plate (ø > 200 mm/8 in) placed under the process connection.
Note, the metal plate should be connected with the process connection directly. When installing
the measuring sensor of the connecting rod or steel rope in the plastic container without a metal
wall, the measuring value will be affected by the strong electromagnetic field (The interference
emission based on EN 61326: Class A). In this case, please use the co-axis measuring sensor.

8 Wiring Instruction
8.1 Preparations
8.1.1 Please Note the Following Safety Precautions before Use:
The instrument wiring is only permitted when it is powered OFF.
If overvoltage occurs to the wire, please install overvoltage protection device to protect the
instrument.
8.1.2 Connecting Cable
The instrument can be connected with the general 2-core wire without the shielding layer
available on the market.
If electromagnetic coupling phenomenon occurs to the installation and wiring environment, and
the value exceeds the inspection value of EN61326-1 Standards applicable to the industrial
field, the cable with shielding cable should be used. For the instrument with housing and cable
screw thread connector, please use the cable with circular cross-section. Please check the
external diameter of the cable applicable to the cable screw thread connector, so as to ensure
the sealing on the cable screw thread connector (IP protection method). Please use the cable
screw thread connector matching with the cable diameter.
Note!
When wiring, please follow the requirements of DIN EN 61140 VDE 0140-1(Protection against
electric shock - Common aspects for installation and equipment), to guarantee the safety
isolation between the power circuit and the grid circuit.
When the cable with shielding isolated mesh is used, it is recommended setting up the
shielding isolated mesh on both sides of earth potential. In the sensor, the shielding isolated
mesh must be directly connected with the internal grounding terminal. The external grounding
terminal on the housing must be connected with the low impedance of the earth potential. For
explosion-proof equipment, it should perform grounding based on the requirements on the
license.
For the electroplating and KKS equipment (cathodic anticorrosion protection), the great
potential difference should be considered. When the shielding isolated mesh is grounded on
both sides, it may cause the current of the shielding isolated mesh to exceed the permitted
scope.
