15. th its technical data fits to the bulk of the object you want to supervise The sensor is sensitive to shock A downfall out lower height to a hard substratum can destroy the sensor The assembling place and the execution of the assembling of the sensor determine decisively the quality of the sensor signal The assembling may only happen through qualified and instructed persons The electrical hook up is to be done by instructed persons A mistake by the connection can entail to faulty functions outfall or ruination of the sensor and electronics The ESW LowCost should not be used on machines with a very energetic high frequency solid borne Through resonance apparitions in the sensor the device can indicate a much too great or too small value Powerful noise sources for instance inverters in direct closeness of the sensor electronics or cabling can result in faulty behaving of the apparatus Potential differences and balance currents in the mass guidance can result in faulty behaving too The connection cable is resistant against many but not every type of chemicals Through a damaged cable chemicals could get inside the unit and destroy the electronic Then the unit would loose their function Therefore the conditions from the mounting surrounding must be checked Then the cover material from the cable have to be proofed if it resists these requirements You can get an overview from the chemical resistance of the cover material fr
