Extensive investment in research and development by Leuze has resulted in a range of opto-electronic sensors capable of reliable detection while simultaneously meeting intrinsically safe specifications.
The Leuze 92 Ex Series are suitable for use in Zones 1 (gases and vapours) and 21 (dust). These devices are available as diffuse reflection light scanners, retro-reflective photoelectric sensors or through-beam photoelectric sensors and are capable detecting objects at distances of between 300 mm and 12 metres.
The compact Leuze 55 Series stainless steel sensors are ideal for areas where explosive risk is minimal, such as Zones 2 (gases and vapours) and 22 (dust). These sensors are developed for all category 3G and 3D applications and with small dimensions they are able to fit into constrained spaces. The stainless steel sensors and their protective housings are designed for resistance to corros-ion and chemicals, making them suitable for use in demanding operating conditions.
The high performance Leuze 46B Series sensors with Zones 2 and 22 certification are used for reliable detection in category 3G and 3D applications. Providing accurate operation even where heavy soiling is present, the sensors are available in a number of variants including through-beam photoelectric sensor, retro-reflective photoelectric sensor or scanner with background suppression.
Leuze 96 long range sensors for Zones 2 and 22 were specially designed for applications that require large ranges of 0,85 to 120 metres in categories 3G and 3D. The product spectrum encompasses all operating principles, including a category 2 protective photoelectric sensor.
Conductivity sensing as a cornerstone of South Africa’s water smart industry ifm - South Africa
Editor's Choice Sensors & Transducers
South Africa’s engineers operate at the intersection of resource constraint and industrial ambition. Few parameters illustrate this balancing act as clearly as water quality. Whether in municipal treatment works, food and beverage plants or mining operations, the ability to measure water quality accurately and continuously has become non-negotiable.
