Dual Hi-Lo Pressure Switch

Dual Hi-Lo Pressure Switches are rugged, field-mounted instruments.

The pressure sensing assemblies are conventional Static “O” Ring type.

The main difference is that two sensing assemblies share a common process pressure port, housing and electrical conduit connection. 

Two discrete sensing assemblies provide independently adjustable, fine resolution Set Points that can be calibrated to the same actuation point, or split to the full span of the adjustable  range without interaction.

• Robust Construction - High cycle rate tolerance, long life, not critical to vibration.
• Instrument Quality - High resolution of Set Points, high repeatability, narrow dead band, negligible temperature effect, high overrange and proof pressures, exceptionally long service life.
• Field Adjustable Set Points - Full range adjustability. No-charge factory calibration.
• Cost Effective - Simple, fast installation without special tools, long service life, no required periodic service or spare parts. Installation of one Dual Hi-Lo provides two pressure switches in the time normally required for the installation 
  of one pressure switch.
• Safety Certified to IEC 61508 (SIL) -  SOR products are certified to IEC 61508 for non-redundant use in SIL1 and SIL2 Safety Instrumented Systems for most models. For more details or values applicable to a specific product.
