Product Announcement from Honeywell Sensing and Internet of Things

These pressure switches can help reduce total cost of ownership and protect operators and critical equipment subsystems. Choose from:

  • High Pressure - Honeywell Pressure Switch - HP Series and HE Series
    • Factory set 150 psi to 4500 psi [10,34 bar to 310,26 bar]
  • Medium Pressure – Honeywell Pressure Switch – ME Series and MH Series (NEW)
    • ME Series: Factory set or field adjustable 25 psi to 350 psi [1,72 bar to 24,13 bar
    • MH Series: Factory set or field adjustable 40 psi to 500 psi [2,76 bar to 34,5 bar]
  • Low Pressure - Honeywell Pressure Switch - LP Series* and LE Series
    • Factory set or field adjustable 3.5 psi to 150 psi [0,24 bar to 10,34 bar]

A wide selection of ports, electrical terminations and compatibility with a variety of media allows use in most industrial and transportation applications, simplifies the design-in process, helps eliminates tooling costs, and helps reduce manufacturing labor costs. Their life cycle rating of up to 2 million, IP67 sealing, and high burst pressures make them one of the most durable pressure switches in the industry.
