Product overview

Application-focused measurement and switching.

The DXBLZALM20 monitors filter restriction with two fixed outputs: an early warning at 75% of the selected set point and a full alarm at 100%. The sensing design is intended to provide reliable contamination indication without false signaling caused by startup or transient flow changes.

Configuration note

Ratings, materials, interfaces, and approvals can vary by ordered configuration. CASCED US confirms the controlled specification before order acceptance.

Key features

  • Independent 75% pre-alarm and 100% full-alarm outputs
  • 1-8 bar selectable set-point range with +/-10% tolerance
  • Designed to resist nuisance indications during startup and flow transients
  • Compact M20 x 1.5 pressure interface and M12 x 1 electrical connection
  • IP67 enclosure for demanding industrial installations
