Product Description:

features:
Owing to adopted advanced micro processor and special Echo processed technology,the radar level meter can be applied in any kinds of complicated working environment
False echo saving function make the meter can select the correct echo out of a large number of interfering reflections,obtained the correct measured results.

Multi process connecting method and antenna shape make CMAXS60 serial radar level meter suitable to any kinds of complicated working environment.for example:high temperature,high pressure and small dielectric constant media measurement and so on.

Adopting pulse work method can make the meter has lower transmitting power,and suitable to install into any metal or non-metal vessel,no harm to people and environment.

 

Principle:
The antenna of Radar level meter emits extreme short microwave pulse to the measured media surface and reflects to the same antenna with the speed of light,the time from emission to receiption of the signals is proportional to the level in the vessel. 
GUIDEPULS60 serial radar level meter adopted special related demodulation technology,they can correctly judge the time from emission and reception of the signals to calculate the distance between the antenna and the surface of measured media.

 

Input:

 

the antenna receive the reflected microwave and transmit to current circuit ,microprocessor processed the signal,to read out the reflected microwave from the surface of the measured media.intellectual software select the correct signal and accuracy can reach millimeter degree.the distance(D) to the measured media is proportional to the running time of the pulse(T)
D=C×T/2 C:speed of light.
empty vessel distance(E) is known,then the level(L)=E-D
Output:
By inputing empty height(E)(= zero point),full vessel height(F)(=Max.measuring range) and some applied parameters to set,applied parameters can make the meter adapting to the measured environment.corresponding to 4-20mA output.

 

When the antenna emits microwaves,there should have emission angel.the area that emited microwaves radiated between the bottom of the antenna and surface of measured media should not have barrier ,so when installing,do best to keep away of facilities in vessel,just like:ladder,limit switch,heating equipment,and bracket.when it is unable to keep away,when installing,we should do false echo saving.we should note that microwave and filling flow can not intersect.the Max. level of the media should not enter into dead zone,there is certain distance between the level meter and vessel wall.when installing,the best is to make the emission direction of the antenna is vertical to surface of measured media.when installing in the area of anti-explosion,we must abide by national installation stipulation,the housing material of the intrinsic safety type level meter is aluminum,it is suitable to install in the anti-explosion area,the housing of the meter should connect to ground.
the area from measured reference plane to the bottom of the antenna is the dead zone of the level meter(reference plane is the seal surface of thread or flange)

Power supply cable can use normal two core cable,the outside diameter should be 5...9mm to make sure to seal the inlet port of cable.if there is electromagnetic interference,use shield cable.

 

4...20mA/HART(two wire) Power supply cable can use normal two core cable
4...20mA/HART(four wire) 

 

CMAXS60 has 3 debugging methods:
1,display/debug module(programmer)
2,upper computer debugging GDPFSOFTWARE
3,HART handheld programmer
display/debug module(programmer)
Programmer is pluggable debugging tool,to debug by 4 keys,after bebugging,it is easy to read measured datas through the display screen of the programmer and display window on the meter cover.

Q:Which is good between pneumatic tools or power tools?
The use of pneumatic tools:1., the air is easy to obtain, and the work pressure is low, the used air can be discharged locally, without the need to recover the pipeline2. gas viscosity is small, flow resistance loss is small, easy to central gas supply and long-distance transportation3. pneumatic actuator, high movement speed4. the pneumatic system has a strong adaptability to the environment. It can work reliably in a wide temperature range, humid and dusty environment, with a slight leakage, no pollution to the environment, no fire and explosion hazards, and safe use5., simple structure, convenient maintenance and low cost6. long life of pneumatic components7. pneumatic actuators of the hydraulic output than small, fast, strong adaptability, can exercise in the flammable, explosive, heavy, damp, the impact of the harsh environment, no environmental pollution, long service life, simple structure, easy maintenance, low price.
Q:What safety problems should we pay attention to when using electric drills and hand-held power tools?
The motor inlet shall be provided with a ground or zero connection device.(4) wearing shoes must be worn while wearing protective gloves such as insulating gloves.(5) each use of tools must be strictly checked.
Q:How are hand powered tools classified into class I, class II, class III?
Nowadays, class I hand held power tools are virtually discontinued. The class II hand-held electric tools are widely used. Class II hand held electric tools are generally used on special occasions such as wet environments, metal containers, etc..
Q:What's the role of carbon brushes in electric tools?
Changing the direction of the current (in the commutator motor brush, also plays a role reversal)
Q:What are the common rotors of power tools?
Electric drill: the main specifications are 4, 6, 8, 10, 16, 19, 23, 25, 32, 38, 13, 49mm and so on. Figures refer to the maximum diameter of the drill drilled on the steel whose tensile strength is 390N/mm. For non-ferrous metals, plastics and other materials, the maximum drilling diameter is comparable to the original specifications of 30 to 50%.Electric grinding machine: a tool for grinding with a grinding wheel or millstone. A vertical electric wheel and electric angle grinder.Electric wrench and electric screwdriver: used for loading and unloading threaded fittings. The driving mechanism of the electric wrench is composed of a planetary gear and a ball screw groove impact mechanism. Specifications are M8, M12, M16, M20, M24, M30 and so on. The electric screwdriver adopts the embedded clutch, transmission mechanism or gear drive mechanism. The specifications include M1, M2, M3, M4, M6 and so on.
Q:Is there an electric tool for screwing bolts? It's bolts, not screws?
Yes, I use it every day. The electric wrench is specially used to tighten the bolts. It has a sleeve with a bolt size at the front, and different sleeves can be changed to screw the bolts of different sizes. It's very convenient and quick to use.
Q:What is the difference between a flashlight and an electric screwdriver?
As the mechanical component, the electric screw driver can work without the electric batch power supply, and the batch power supply provides the energy and the related control function for the electric screwdriver. Drive the motor. Since the parameters of the motor are different, the speed will be different when the power of the batch power supply is the same.
Q:Power tools are power tools?
General refers to power tools, and in some cases pneumatic tools are used.
Q:How are the I, II, and III classes of power tools classified?
In accordance with the electric shock protection methods, electrical equipment is divided into the following 4 categories:0 category. The device relies solely on basic insulation to prevent electric shocks. There are no ground terminals on the live conductors of the 0 types of equipment.
Q:What kind of power tools are hand drills? 1, 2 or 3?
I class: in the prevention of electric shock protection, in addition to relying on basic insulation, but also the need for zero protection.Class II: the tool itself has double insulation or insulation without the need to protect the ground.Class III: Powered by a secure, ultra low voltage power supply, no voltage higher than the safety supply voltage is generated within the tool.The above is the classification of insulation categories.
