Measuring principle
/Net111Edit/UploadFile/20091111103510242.swf   The pressure sensing element of the UE Pressure Switch is a force-balance, piston-actuated assembly. The sensing element is sealed by a flexible diaphragm and a static o-ring. There are only three wetted parts in this arrangement: a pressure port, a diaphragm and an o-ring. A wide selection of wetted parts materials for media compatibility and containment is available. A metal diaphragm may be welded to the pressure port for certain applications, thereby eliminating the o-ring Media pressure on the piston counteracts the force of the range spring (adjustable by the adjusting nut) which moves the piston shaft only a few thousandths of an inch to directly actuate the electrical snap-action switching element that is enclosed in the hermetically sealed steel capsule. This design results in low friction and virtually no wear. The electrical switching element is isolated from corrosive atmosphere

Product list
  • 24series UE Pressure Switches

  • 120 Series UE Press.switch

    As safety requirements become more stringent, the determining factor in specifying an industrial pressure, differential pressure and/ or temperature switch rests upon that switch protecting equipment, processes and personnel. Meeting hazardous location requirements through adherence to UL, CSA, and ATEX standards, UE¡¯s 120 Series is the choice where potentially explosive or highly corrosive atmospheres exist.

  • The UE 100 Series Pressure Switch

  • 400 Series the UE mechanical pressure switch The 400 Series is a versatile family of vacuum, pressure, differential<BR>pressure and temperature switches for applications that require single or multiple switching capabilities. Dual and triple switch versions provide multi-output for alarm and shutdown, pre-alarm and alarm,<BR>high/low limit or level staging functions.

  • J6 Series UE Pressure Switches

  • 117series UE Pressure Switches

  • The UE 10 Series Pressure Switch the 10 Series is designed to meet most requirements for a variety of OEM and industrial applications. Just 1-1/4 inches in diameter and as small as 3 inches high, this compact, cylindrical switch mounts wherever space is at a premium. A reliable and cost-effective switch, the 10 Series is ideal for applications with high settings and surges. Among the tough applications in which the product has proven itself are: mobile hydraulic units, compactors, balers and lube oil systems.
