New solutions for safe electrostatic grounding in hazardous areas
Thanks to continuous monitoring of the earthing connection, grounding monitoring devices ensure safety in hazardous areas
The grounding monitoring devices are suitable for outdoor installation and can even be used in extreme climates (-50 °C to +60 °C). Both types are equipped with an IP65 housing. 8485 devices are designed for use in zone 1, while the 7485 series has been optimised for installation in zone 2 as well as zone 21 and 22 hazardous dust atmospheres. A two-channel version, i.e. a model with two earthing clamps, allows for efficient monitoring of combined loading units, e.g. trains and trucks. In that case, the monitoring mode can be individually adapted to the application for each of the two clamps. In addition to the corrosion-resistant earthing clamp with good contact pressure, the solution includes a robust, oil-resistant cable. The clamps are available with simple cables, spiral cables or an automatic retractor suitable for use in zone 1.

Energy-efficient LED beacons from R. STAHL
In addition to tried-and-tested models with halogen and xenon flash lamps, R. STAHL's 6162 line of signal beacons now also includes energy-saving LED-based continuous beacons and rotating beacons. With little self-heating, these new models are suitable for use in Ex zones 1, 2, 21, and 22. They fulfill the requirements of temperature class T6 and surface temperature for dust explosions protection T80 °C, and come with an integrated "increased safety"
Completely wireless switching devices for ATEX zones 1, 2, 21 and 22
R. STAHL's new 8074 F series position switches and 8040 F series command devices are truly, completely wireless solutions for radio signal communication. Requiring neither signal lines nor external energy supply connections, the units can be freely installed in zone 1, 2, 21, or 22 hazardous areas. Users therefore need not worry about any wiring when e.g. retrofitting the command devices into difficult-to-access machines or plants. Since there is no
Modular UPS solutions for hazardous areas
R. STAHL provides uninterruptible power supplies for hazardous areas which ensure the safe operation of systems that require 100% availability. The UPS units are assembled from a modular design kit and can be optimally adapted to specific applications. They can be used to safely bridge complete blackouts or malfunctions in the mains power supply, such as frequency fluctuations or overvoltages caused by lightning strikes which can result in plant downtime.
