Larson Electronics has released an explosion proof, magnetically operated, leak proof float switch that allows operators to control tanks by starting and stopping pumps, opening and closing valves and actuating level alarm signals. This float switch is NEC, CEC, ATEX and IECEx certified with NEMA 4 weather-proofing.
The company says that the EPSW-FLS-1KPS-10A float switch is highly reliable since it contains no bellows, springs or seals that might fail under rugged long-term use. Instead, this unit has a free-swinging float switch which attracts the magnet located inside the switch’s metal body. Once this happens, a snap switch with a lever arm is actuated.
External protection is provided by an ATEX and IECEx certified housing with weather proof, explosion proof and NEMA 4 ratings. Built from durable brass, the float switch can withstand up to 1000 psig of pressure.
Single pole and double pole snap switch models are available, both with a three-quarter inch deadband requiring minimum specific gravity of 0.7. Options for electrical connection are also available, which include a 6-inch cord and flying leads for NEC/CEC models only, or terminal strips for ATEX/IECEx models, both providing safe and efficient electrical connection in hazardous locations. This explosion proof float switch operates on 125/250 volts AC at 10 amps and provides a three-quarter inch conduit connection as well as a 2-1/2” male process connection. Operators can easily install this magnetically operated float switch directly inside the tank with a wall-mount.
“Standard float switches contain parts that increase the chance of mechanical issues or total failure,” said Rob Bresnahan, CEO of Larson Electronics LLC. “Operators can benefit from this explosion proof float switch because it is magnetically operated, meaning it doesn’t contain any of those extra bits and pieces. Combine that with its certifications and it’s easy to see how reliable and safe it is for operations in dangerous environments.”
