It is national standard measuring method to dry weight method, and precision is high, but measuring speed is slow, a small amount of sample moisture content can only be tested, no
Online quick test can be used for, and only reflect the water content of sample, because material moisture is typically not uniform, sample is aqueous
The average moisture content of amount and true material there may be deviation, therefore reflect that the average moisture content needs of true material repeatedly take
Sample measurement carries out statistical analysis, and test period is long, and efficiency is low.Infrared reflectivity aquametry is to spy using different moisture content sample
The difference of the long infrared reflection rate of standing wave, by measuring infrared reflectivity come inverting sample moisture content, can be used for on-line testing,
But reflected because infrared ray is main in surface of material, the penetration depth to material is small, therefore be mainly used in measurement material top layer and contained
Water, it is difficult to carry out the accurate survey water of material body water content.
Microwave radar type detecting system is to obtain measured medium to the saturating of specific standard electromagnetic wave using radar detection technique
Penetrate or reflect (or being rescattering) and propagate information to determine the detecting system about moisture size in medium, be to have
Good measuring accuracy and the average body water cut test technology of the non-contact type of stronger versatility, Quick material.But existing microwave

The limitation of itself, improves diversity and flexibility that it is used.
The antenna house scribbles waterproof coating with rear cap surface, and this equipment may be long-term exposed to outdoor, therefore entirely sets
Standby system has rainproof function.
The bonnet and peace turn to be provided with fan between bottom plate, and after cover and offer heat emission hole, equipment is due to having one
Fixed heating, therefore add the operation reliably and with long-term that fan carries out radiating guarantee equipment.
The bottom of the bonnet is connected with fixed component, and the fixed component, which is used to fix MOISTURE MEASUREMENT SYSTEM, avoids it
Generation activity is stolen, and when the system needs to be placed on outdoor carry out moisture content detection for a long time, passes through fixed component
The system is connected with other outdoor retaining elements, can avoid being damaged and being stolen.
Also include being arranged on the temperature-adjusting device below antenna house, the temperature-adjusting device includes refrigeration and heated,
Can be according to the temperature in outdoor environment adjusting device.
The present invention compared with prior art, has the following advantages and advantages：
1st, a kind of radar type MOISTURE MEASUREMENT SYSTEM of the invention, test system is integrated in all-in-one, not only with good
Measuring accuracy and stronger versatility, while mobility is strong, can carry anywhere or environment carries out the detection of moisture, no
The limitation of examined equipment in itself, improves diversity and flexibility that it is used；
2nd, a kind of radar type MOISTURE MEASUREMENT SYSTEM of the invention, the antenna house scribbles waterproof coating with rear cap surface, originally sets
It is standby exposed for a long time to arrive outdoor, therefore whole equipment system has rainproof function, the bonnet and peace turn setting between bottom plate
