  • 120 Series Models
  • UE Series 120 for differential pressure measurement
  • UE 822 Series for temperature measurement
  • UE 120 Series

The 120 Series consist of pressure, differential pressure and/or temperature switches. Meeting hazardous location requirements through worldwide approvals and certifications, UE’s 120 Series is the choice where potentially explosive or highly corrosive atmospheres exist.

Because of its wide variety of sensor materials (adjustable set point ranges and wetted parts materials) the 120 Series is one of the most popular UEC's products.
