In places classified as a potential explosion hazard, it is compulsory to use suitable equipment to the area of use, that is bearing the ATEX certification.
EUROSafe Italia S.r.l. offers a range of carefully selected devices from high end equipment manufacturers to meet the most varied demands of the market also for the cases which are more difficult to manage.
In particular, EUROSafe Italia S.r.l. markets the following control systems:
The pressure sensor continuously measures the absolute pressure inside the sensor tube. The sensor signals are mathematically analysed by the microprocessor and can therefore be used for calculations and to realise the differential behaviour. If the pressure increases to the software-defined speed (mbar/s), the ADW511A signals a "differential alarm". Disturbance variables, such as slow pressure changes or or pressure blows (as a result of weather-related temperature fluctuations, high volumes of vehicle traffic in tunnels) are "filtered" out according to their temporal behaviour, so as not to trigger an alarm. The sensitivity of the detector can be set with the software.
The maximum behaviour of the ADW511A is designed so that the pressure value corresponding to a determined maximum temperature triggers the alarm. The slow and steady growth of the pressure over a long period is not enough cause for the differential function to intervene (e.g., ΔT=40°C/h; overheating of an oven) is then interpreted as a "maximum alarm" when it reaches a certain threshold. A temperature sensor in the detector box continually measures the current ambient temperature and derives the reference value for the maximum evaluation value. In addition, when it exceeds a temperature of 70 °C within the detector box, this temperature sensor transmits a "temperature sensor alarm".
