Explosion-proof distance meters and sensors for precise distance measurements

The explosion-proof distance meters and laser distance sensors of the LDx, LTG and TDD product families - measurements accurate to the millimetre and micrometre for Ex zones 0, 1, 2, 20, 21, 22

Laser Distance Sensor

LDx
Laser Distance Sensor (LDH)
  • Exact, precise and millimetre-accurate measurement using time-of-flight measurement 
  • Ranges up to 30000 mm with a resolution of 1 mm
  • Suitable for matt, glossy and different coloured - even black - objects
  • Explosion-proof, robust stainless steel housing M42 in flameproof Ex "d" enclosure
  • Approved for Ex zones 1, 2, 21, 22 (gas and dust Ex)
  • Optical power limitation - sensors may radiate in zones 0 and 20
  • New! Devices with front panel heating and selectable laser timing
  • Protection class IP67

Laser Triangulation Sensor

LTG
Laser Triangulation Sensor
  • explosion-proof, flameproof encapsulated, laser triangulation based on Micro-Epsilon sensors
  • Micrometer-accurate distance measurement
  • Repeatability < 10 µm
  • Mounting directly in Ex zones 1, 2, 21, 22, measurement by optical power limitation into Ex zones 0 and 20
  • Measuring ranges with lengths from 10 mm to 500 mm
  • Output via digital RS422 interface and configurable analog interface 4–20 mA
  • Precise distance measurement with a repeatability of < 10 µm
  • High measuring rate up to 2 kHz
  • Stable measuring values independent of the color and brightness of the target object
  • Easy alignment due to visible laser light
  • Aluminium housing, degree of protection IP65, Ex “d”

Infrared distance sensor

TDD
Infrared distance sensor
  • Precise and centimetre-accurate time-of-flight measurement (according to the time-of-flight principle)
  • Infrared light 860nm with a measuring range from 100 mm to 1000 mm
  • Works independently of the reflectivity of the object being measured
  • Explosion-proof, robust and compact M30 metal housing in flameproof Ex "d" enclosure
  • Approved for operation in Ex zones 1, 2, 21, 22 (gas and dust Ex)
  • Optical power limitation - sensors may radiate in zones 0 and 20
  • Versions with switching function and analogue
  • output 4-20 mA
  • Protection class IP 67

Optical distance sensors

TMD
  • Distance measurement through direct time-of-flight (direct ToF)
  • Directly usable in Ex zones 1, 2, 21, 22; allowed to emit into Ex zones 0 and 20
  • Typical distance measurement up to 2 m, up to 4 m with a suitable target surface
  • Adjustable beam angle
  • Measurement output via RS-485 interface and configurable current interface 4–20 mA.
  • Switching output activates when a freely configurable distance is exceeded or falls below the set threshold
  • Laser class 1
  • Infrared light
  • Explosion-proof housing made of aluminum
  • Protection class IP65
  • Simple configuration via menu system (RS-485) or from a control system (PLC)
