Whenever there is an unclear problem with our surveillance signals, we may all consider whether it is an interference problem. It is true that in our era of "wireless" today, it is not an easy task to completely get rid of interference, and external interference will affect our wireless transmission effects more or less. So how do we avoid interference?
Similar equipment interference
Avoid signal interference from similar devices in the surrounding area or the same equipment. The signal source of this interference signal may be a normal signal source in our system, and may be due to the same frequency or similar, resulting in the receiving terminal receiving no or receiving the same signal, making the receiving terminal difficult to identify. For this situation, we can adjust the frequency of the wireless device, select a clean channel, or change the position of the wireless device transmitter or receiver, and pull the distance between the devices.
Construction disturbance
Buildings have a debilitating effect on the transmission of wireless signals. When the wireless signal passes through any object, its electrical signal will be refracted to a certain degree, causing its transmission direction to undergo a certain change, and will cause reflection and attenuation of the signal. If you encounter a metal object in the transmission, it will increase the attenuation of the signal. Therefore, when selecting the installation position of the wireless device, the middle of the wireless device can be shielded as much as possible and visible from the middle of the transmitting end to the receiving end. This avoids the attenuation of microwave signals and the monitoring center can receive high-intensity wireless signals, thereby improving Monitor effect.
It is not a device that interferes with wireless, such as mobile, Unicom towers, walkie-talkies, wireless phones, etc. These have no effect on wireless microwave equipment. In the case of interference sources, we can adjust the frequency of the equipment or choose a location that is farther from the source of the interference. This will greatly reduce the interference to wireless microwave equipment.

Stainless steel Flanges are essential accessories for pipeline connections. According to the standards, they are divided into JIS BS DIN ANSI GOST Italian standards. Among them, DIN, JIS, BS standard non-Carbon Steel Flanges are the most common, popular and widely used. flange. Stainless steel flanges are divided into two processes: forging and casting. Among them, cast stainless steel flanges have low price and stable performance, and are widely used in Europe and South Korea
The biggest features of stainless steel flanges are good stability, strong corrosion resistance, acid and alkali resistance, and are widely used in pipeline systems in chemical, pharmaceutical, food, pharmaceutical and other special industries.
When in use, the flange is evenly welded to one end of the pipeline with a special electrode, and then fastened with bolts to effectively connect the pipeline, valve, pump and other equipment accessories, so that the entire pipeline is integrated and starts to work normally.
It is an indispensable pipe fitting that must be used in pipeline systems and equipment such as machinery, petroleum, chemical industry, water conservancy, medicine, food, and papermaking. It provides convenience for the cleaning, inspection and maintenance of the pipeline and reduces the engineering cost.
Types of stainless steel flanges:
According to the shape can be divided into: FF, RF, BLIND, SLIP-ON, Welding Neck
, Threaded , Socket Weld
According to the pressure can be divided into: PN10, PN16, PN25, PN40, PN63, PN100,
15OLBS.300LBS
According to the process, it can be divided into: forging flange, precision casting flange, steel plate flange
According to the material can be divided into: SUS304 SUS304L SUS316 SUS316L 321 201
According to the production process, it can be divided into: a: forged flange b: stainless steel plate flange c: precision casting stainless steel flange
