ExBin-P pressure/differential low pressure switch (pressostat)

Binary pressure/differential pressure switch ΔP
Low pressure sensor (Pressostat)

NEW: Binary differential pressure switch ExBin-P-100 with adjustable switch activation delay, for low pressure from 0-100 Pa
Measurements ..Bin-P Sensor: L × B × H = 177 × 107 × 66 mm

Measurements in mm

Description – Binary digital differential pressure switch (Pressostat) ExBin-P..

  • Binary electric digital pressure switches (Pressostats) for HVAC systems, e.g. for differential pressure control for filter- or fan belt monitoring
  • No additional module in the panel required!
  • No intrinsically safe wiring required!
  • All parameters adjustable on site w/o additional tools/meas. devices
  • Pressostat ExBin-P-100 with differential pressure range from 0 - 100 Pa allows an achievement of new applications with a smaller differential pressure range
  • Additionally the ExBin-P-100 has an adjustable switch activation delay contact for applications which require a time-delayed fault indication, for example short opening of doors in clean room environment
