SOR Mini-Hermet pressure switches are robust field-mounted instruments with an ATEX flame proof, UL and CSA explosion proof rating.
The pressure sensing assembly is similar to a conventional SOR type pressure switch, except the switching element assembly is hermetically sealed and the product is in an explosion proof stainless steel or aluminum housing. The diaphragm o-ring provides initial protection backed by a hermetically sealed snap switch for a second line of protection – dual seal standard ANSI/ISA -12.27.01-2003.
“Mini-Hermet pressure switches are recommended for a variety of process applications in hazardous locations and hostile environments where stainless steel and aluminum exterior parts are required and where space is limited.”
says SOR Product Manager, Michael Lian,
“A few examples of places you might see this product would be panels for offshore platforms, and lube oil systems.”
The Mini-Hermet is very price competitive within the market. A simple, fast installation without special tools and long service life make it a very cost-effective product.
