400 Series Overview
Pressure, Vacuum,
Differential Pressure and Temperature Switches
The 400 Series is a
versatile family of vacuum, pressure, differential 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, high/low limit or level staging functions.
A wide variety of
microswitch and process connection options, along with a weather-tight
enclosure, make the 400 Series an ideal choice for most ordinary location
applications. Its worldwide use is assured with approvals and certifications to
agency standards.
Widely used
throughout the process industries, the 400 Series provides threshold protection
and control for many critical functions. Typical installations are found in
industrial gas production, energy generation including pumps, turbines and
compressors, pulp and paper, and water and wastewater treatment
