1500 Series mechanical switch

SOR® Flameproof Products Can Offer the Most Cost Effective Application Solution 

Lenexa, Kan. – SOR Inc. announced today that key products in the company’s 1500 series(PDF) of mechanical level switches have been certified as Flameproof. SOR is one of very few monitoring and control companies that offer the Flameproof rating.

The right choice in a protection standard can help save money, time and the cost of modifications to the product in the future, so SOR offers multiple certification options to provide the best fit for the application and location.

The Flameproof protection standard certifies that the instrumentation will withstand an internal flame or explosion. According to the ATEX directive, this equipment is intended for medium-risk hazardous areas where an explosive atmosphere may occur under normal operating conditions. Hazardous Areas are those areas of a plant or facility that have a likely presence of explosive mixtures of gas, vapor or dust according to SOR Engineer, Sara Roos.

The Flameproof rating is part of the ATEX Directive 94/9/EC. The 1500 series is a less expensive alternative to the traditional chambered switch. The 1500s are suitable for most any point level application. This certification will expand on the OEMs ability to sell the SOR 1510, 1520 and 1550 model mechanical level switches worldwide. The 1500 Series of products currently have a CSA Explosion Proof Certification and an ATEX Intrinsic Safety listing.

“As a global company with significant sales outside of North America, SOR is meeting the needs of countries around the world that require or prefer a Flameproof listing”, says Jason Aldrich, SOR Product Manager.

The SOR lines of pressure and level switches are rugged field-mounted instruments. Nearly every SOR product can be designed to meet the demands of the process and engineered-to-order. SOR offers quick delivery that matches or exceeds off-the-shelf suppliers.
