1. The lightning protection of wireless monitoring equipment must be done. The lightning protection engineering in the wireless monitoring system is indispensable, including the two major parts of lightning protection and wireless monitoring equipment surge protection. When a lightning strike occurs, the lightning discharge induces a lightning strike overvoltage and overcurrent of the electromagnetic pulse. The power monitoring system, the signal transmission, the grounding system, and the building direct lightning protection system can damage the wireless monitoring equipment and other weak electrical equipment through conduction and induction.
Found in many wireless monitoring projects, many customers with a lightning arrester, but also installed and used, but did not do a good deal of grounding, lightning protection, if not grounded, there is no lightning protection as do the same. Therefore, lightning protection must be done to prevent lightning.
2. Waterproof Waterproofing of Wireless Monitoring Equipment Most of the wireless monitoring equipments produced by Shenzhen Leian Technology belong to the waterproof type. For a small part of non-waterproof equipment, the wireless monitoring equipment must be well waterproofed. Although the wireless monitoring equipment is waterproof, waterproofing at the adapter is the easiest place for everyone to ignore. Although the connector is at the bottom of the device, the rain cannot enter from the front, but for a long time the rain will fall back into the device along with the cable. Therefore, waterproofing at the head of wireless monitoring equipment is essential. It is also necessary to make the power supply waterproof, so that the wireless monitoring equipment is not stable due to unstable power supply.
Many customers will worry that wireless monitoring equipment will produce rain failure in rainy days, leading to unstable signals. This can be assured when you use it. Manufacturers have already taken into consideration the external factors such as rain failure when designing for you. The stable transmission of your wireless monitoring system.
Nitrile rubber (NBR) o-rings, also known as Buna N, are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds.
Acrylonitrile Content
The acrylonitrile (ACN) content of the polymer chains can vary from 18% to 50%. Lower ACN content gives better low-temperature properties but inferior resistance to fuels and polar lubricants. Higher ACN content gives lesser quality low-temperature properties but improved fuels and polar lubricants resistance. Standard NBRs typically have 34% ACN content.
Standard Nitrile o-rings are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high temperatures. Peroxide-cured nitrile o-rings have better heat resistance and lower compression sets but are more expensive and more difficult to process.
Buna O-rings, Nitrile O-rings, NBR O-rings offer excellent sealing and mechanical properties at low cost. Buna Nitrile O-rings have resistance to common lubricants and are recommended for crude oil, gasoline, propane, petroleum oils and water. Nitrile Buna O-rings are used in engines, gearboxes, aircraft pumps, and water applications.
