SQ-4 Series - Safety Liquid Leak Sensors - Category 4 Rated

SQ-4 Series - Safety Liquid Leak Sensors - Category 4 Rated

Safety Leak Sensor for Water & Caustic Chemicals

  • Category 4 Rated - when used in combination, the SQ4-A sensor and SQ4-C11 controller meet Category 4/PLE/SIL3 requirements under ISO 13849-1:2008
  • Two-Stage Detection - dual sensing outputs provide both a warning and safety-critical output for differentiation of leak severity
  • Multiple Sensor Inputs - Up to four sensors can be connected to each controller
  • Independent Operation - Sensor heads can be used independently of the controller, meeting a Category 1 rating
  • Safety Input Function - Allows daisy chaining of multiple controllers along with safety peripherals such as e-stop and door switches

The SQ-4 Series is one of the first leak sensors in the industry to earn safety certification, demonstrating that it delivers safety performance of the highest caliber. Featuring a two-stage detection system for improved productivity, the SQ-4 simplifies preventative maintenance and maintenance planning.
