1. Warranty and service scope of radar level sensor

The warranty period of the radar level sensor is one year from the date of delivery,

and the warranty period of repair and maintenance is half a year. This warranty is

only limited to the users of the original buyer or the designated dealer, and does

not apply to users who use it wrongly for human reasons, transform, neglect or damage

it due to accidents and abnormal use.

For the faulty radar level sensor returned within the scope of warranty, free

maintenance is provided. To obtain warranty service, please contact the after-sales

service department and attach the fault description. With the permission of our company,

send the radar sensor to the after-sales service department.

If the radar level sensor has expired the warranty period or it is confirmed that the

failure is caused by misuse, modification, negligence, accident and abnormal

conditions, the maintenance cost budget will be provided according to the relevant

maintenance charge standard, and the maintenance will be carried out after it is

approved. After the radar level sensor is repaired, it is sent back to the customer,

and the customer needs to pay the maintenance and transportation costs. (Attachment:

warranty)

2. Unpacking inspection and precautions

2.1 Unpacking inspection

Instruction manual

Certificate of conformity

Packing list

Radar Level Sensor

Check the name, model and other contents on the nameplate

Check whether the radar sensor housing is intact and observe

Check the random items against the packing list

Check whether the specifications, models and accessories are correct and complete

according to the packing list of the radar level sensor. If there is any problem,

please contact the customer service center in time for replacement.



2.2 Precautions

Please read this manual before installing the radar level sensor.

Modifications due to product upgrading are subject to change without notice. Please

refer to the real object.



3. Storage and transportation

3.1 Storage conditions

Temperature：–40～+60 ℃

Use the original packaging

3.2 Transport the product to the measuring place

Use the original packaging to transport the radar sensor to the measuring place

Collision, dampness and chemical erosion shall be prevented during

transportation and storage

4. Product introduction

4.1 Product Overview

76-81ghz frequency modulated continuous wave (FMCW) radar products (also known as

millimeter wave radar) adopt the millimeter wave band with higher frequency than Ku

band radar. They have important applications in long-range target detection,

long-range imaging, multispectral imaging in strong smoke and dust environment, and

can detect smaller targets than microwave radar and achieve more accurate positioning,

with higher resolution and stronger confidentiality.

As a 78GHz band radar used in the field of industrial measurement, high-precision,

non-contact level and liquid level measurement has incomparable advantages over other

ordinary microwave pulse radars and guided wave radars. With extremely narrow beam

and penetration ability, it can better adapt to ultra complex working conditions

without weakening the measurement performance.

4.3 Application

4.3.1Measured medium

In general, the dielectric constant of the measured medium is required to be greater

than 2, so that it can have a good reflection cross section

4.3.2Ambient temperature of radar level sensor

The ambient temperature range of radar level sensor is: -20 ℃~ +70 ℃.I n areas with

strong sunlight, it is recommended to install the instrument in a cool place or use

a sunshade, which can not only avoid the excessive temperature in the instrument caused

by exposure to the sun, but also provide good ventilation and heat dissipation.

4.3.3Protection grade

Waterproof and dustproof grade: IP67

7.3.2 Setting range and definition of basic parameters

Basic settings：

Range（500~50000）mm：It depends on the working condition; Indicates the longest

distance that the level sensor can measure.

Migration（-9999~9999）mm：It depends on the specific working conditions

4mA Position:4mA Level corresponding to current output，Unit mm

20mA Position：20mA Level corresponding to current output，Unit mm

Blind zone：The range is 200mm to the measuring range, which is set according

to the specific working conditions

Display type：level value / space distance value

Damping time：In order to improve the stability of the measured output value,

a larger [damping time] can be set to achieve the stability of the measured value

and increase the anti-interference ability. For example, when the damping time

is 10, the measured object level changes step at time t, and the measured output

value follows the actual position of the measured object after 10 seconds.

Device address：During RS-485 communication, the slave address is the local

address (value range: 1-99, default value: 1).

Baud rate：The baud rate of this device during RS-485 communication is 9600

by default.

Backup user parameters:

After the working parameters are backed up, if you forget the original working

parameters after manually modifying the parameters, you can "restore" them in

the basic settings.

Restore user parameters:

Used to restore the backed up user parameters.
