Explosion-proof Wireless Vibration Sensor "conanair" | Zero Wiring Work in Hazardous Areas

The explosion-proof conanair (CNA-WLVS-02E) is a fully wireless vibration sensor developed for hazardous locations (explosion-proof areas) such as chemical plants and oil refineries.

When introducing conventional wired sensors into explosion-proof areas, "explosion-proof wiring work," which requires enormous costs and time, was absolutely necessary. By utilizing a Wi-Fi network, the explosion-proof conanair completely eliminates this wiring work, allowing you to build a predictive maintenance system in hazardous areas at an overwhelmingly low cost.

Received the "Excellence Award" at the 36th Excellent New Technology/Product Awards for SMEs

The explosion-proof conanair was highly evaluated for its innovation and reliability, receiving the "Excellence Award" at the 36th Excellent New Technology and New Product Awards for SMEs.

This award is sponsored by the Resona Foundation for Small and Medium Enterprise Promotion and the Nikkan Kogyo Shimbun, and is known as one of the largest technology awards in Japan, where excellent new products and technologies are selected through rigorous screening. Its solid technological capability, recognized even by public institutions, supports safety and efficiency at many manufacturing sites.

Reducing Enormous Explosion-proof Wiring Costs to "Zero": Advantages of Fully Wireless

The greatest advantage of implementation is the significant reduction in costs and construction period. It is not uncommon for wired installation work in explosion-proof areas to cost millions of yen, but since conanair is fully wireless, it can be installed with zero construction costs.

• Utilization in manual measurement: Using explosion-proof tablets or explosion-proof notebook PCs, patrol and spot vibration measurements within hazardous areas can be easily performed.
• Utilization in automatic measurement: As long as there is a Wi-Fi environment, automatic continuous monitoring starts simply by retrofitting it to the equipment without any wiring work.
• Partial explosion-proof support: Because it can be used in a mixed manner within the same system as the standard conanair for non-explosion-proof areas, it is possible to provide explosion-proof support only for pinpointed hazardous areas within the plant.

Explosion-proof Performance and Specification Details of conanair (CNA-WLVS-02E)

The pressure-resistant explosion-proof case is developed and manufactured by Nakamura Electric Mfg. Co., Ltd., a specialized manufacturer of explosion-proof equipment. It boasts extremely high safety performance that clears not only domestic certifications but also global explosion-proof standards (ATEX, IECEx).

The acquired explosion-proof specifications are as follows:

The specific performance and applicable scope indicated by these symbols are as follows:

• Flameproof (d/db): Even if an explosion occurs inside the case, it has a robust structure that will not ignite the surrounding explosive atmosphere.
• Hydrogen/Acetylene support (IIC): Can be used in all target gas environments, including hydrogen and acetylene, which are considered to have the highest risk of explosion.
• Temperature class (T6): The maximum surface temperature of the electrical equipment is suppressed to 85°C, making it safe even in gas environments with a low ignition point.
• Dust explosion-proof (tb IIIC): Supports not only flammable gases but also harsh dust environments where conductive dust scatters (Zone 21, 22, etc.).

Target Audience and Expected Installation Sites

 

Because it achieves both explosion-proof and dust explosion-proof support, as well as "hydrogen support," it plays an active role in a wide range of sites with hazardous areas, regardless of the industry.

• Chemical plants, oil refineries, gas facilities (including hydrogen-related facilities)
• Facilities that store and supply fuel (airports, port terminals, etc.)
• LNG/LPG receiving terminals, coal-fired power plants
• Painting factories handling flammable solvents
• Food factories (chocolate factories, etc.), pharmaceutical factories, and cement factories with a risk of dust explosion

Differences from the Standard Model and Basic Specs

The explosion-proof conanair is clad in a robust explosion-proof case, but the internal board and communication performance are exactly the same as the standard ultra-long life model (CNA-WLVS-02X). Therefore, it is possible to acquire raw data using the patented "under-sampling" technology just like the standard model.

• Mounted board/communication performance: Identical to CNA-WLVS-02X (ultra-long life model).
• Usable battery: CR123A (1,550mAh). *Due to strict explosion-proof certification regulations, Panasonic batteries are specified. Please note that CR123A batteries from other manufacturers cannot be used.
• Housing: Special case with pressure-resistant explosion-proof and dust explosion-proof specifications (manufactured by Nakamura Electric Mfg. Co., Ltd.)

Estimated Lead Time and Price

To deliver safety and predictive maintenance to our customers' sites as quickly as possible, we maintain a system of keeping "approximately 50 units" constantly in stock for all models, including the explosion-proof model.

• Orders of less than 10 units: Can be shipped within a minimum of 3 days.
• Orders of about 50 to 100 units: Can be delivered within about 1 month. (Estimate based on numerous delivery records)
• Orders of 100 units or more: Treated as build-to-order, with a lead time of about 2 to 3 months.

In terms of price, in addition to the advantage of eliminating the need for enormous wired construction costs, the total cost of the sensor unit and peripheral equipment is kept at an overwhelmingly low price range compared to similar explosion-proof wireless sensor systems from other companies. It is possible to increase the number of equipment subject to monitoring within the limited budget of the site.
