UL and cUL Listed and CSA Certified
This hazardous location strobe light provides 80 high intensity flashes per minute. This warning light is available in 12-24VDC, 24VDC, 120VAC and 240VAC.
The warning light has been certified by UL as meeting Type 4X watertight and corrosion-resistant requirements and is constructed to IP66 (in dome up orientation). This hazardous location warning light has a black polyurethane coated base and the inner fresnel lens is available in five colors. The clear polycarbonate outer dome can be quickly removed for easy access to inspect the unit or change the lamp. It produces 240 effective candela and a 580,000 peak candela.
It also features a voltage in-rush limiting PCB design that provides greater compatibility with factory automation control systems and less electrical interference with in-rush sensitive devices. It is UL Listed and CSA Certified for Class I, Division 2, Groups A, B, C and D; Class II, Division 2, Groups F and G; and Class III. It is ideal for wet, corrosive atmospheres like those found in food processing industries, or anywhere a visual signal is needed.
An affordable Strobe Warning Light is specifically designed for use in hazardous locations or where corrosive materials are present.
Available on our Series N Flow Switch – these units are furnished with a slip-on steel cover. This .062 thick housing is NEMA 4X weather proof, by utilizing a special “O” ring seal fitted into a mechanical groove in the body; a standard on all of the non-explosion proof models. The housing & cover are both made of heat treated aluminum T-356 and are epoxy coated (for extra protection). Each of the four basic styles shown are adaptable to many other fittings and configurations.
Available on our Series E Flow Switch – All explosion proof models are rugged, heavy duty units exceeding all UL Code requirements. Each of the four basic styles are adaptable to many other fittings and configurations. Utilizing 1/4″ thick Heat treated aluminum cover (shown at right) with 5 fully engaged threads, these units are designed to encapsulate any internal explosion. All explosion proof models meet Class 1, Group D requirements for use in hazardous locations; all NEMA classifications available. The housing & cover are both made of heat treated aluminum T-356 and are epoxy coated (for extra protection). Other classes and groups are available. Conduit outlet: 1/2″ NPT on all models; 3/4″ and metric sizing available.
Available on our Series H Flow Switch – Utilizing ¼” thick Heat Treated aluminum cover with 5 fully engaged threads, all units are designed to encapsulate any internal explosion. In lieu of a bellows assembly a solid rod extends through a flexure tube brazed or welded into a S.S. ball fixture. Unit has been successfully field tested up to 10,000 psi. Wall thickness of the flexure tube will vary with pressure requirements. This model is recommended for all pressures over 600 psi. Each of the four basic styles shown are adaptable to many other fittings and configurations.
