Model: LD-450/SD sensor

LD-450/SD sensor

  • Flexible setup layout. The oxygen sensor and low-profile converter are separated, greatly relaxing limitations on where the device can be installed.
  • Space saving. The newly developed low-profile wall mounted converter eliminates concerns about the device’s depth.
  • Ultra-high-speed response. The separated sensor provides the fastest response speed.
  • Highly durable sensor. A special coating is used for even greater durability.
  • Applicable Standards
    CE Marking: EN 61010-1, EN 61326-1
    RoHS Directive: EN 63000
    Applications
    Sputtering systems; equipment gas purity management; factory piping argon (Ar) welding management; experimental equipment; and testing equipment.
  • Sensors are compatible with NW flanges (16, 25, 40) for vacuum and screw-in units (3/8R).Select the appropriate type for use condition.

Installation example (SD sensor and LD-450 converter work in pairs.)
