Patol 11-1000001-01P ADW 535-1HDx ADW 535-1HDx Line Type Heat Detector - 1 Sensor

The ADW 535HDx is an integrating line type heat detector that consists of the evaluation unit and one or two sensing tubes. The sensing tube is made of copper (Cu), stainless steel (St) or Teflon (PTFE).The ADW 535HDx is suitable for operational use in explosion hazardous areas of zone 2 and 22 in accordance with VDE 0165 and IEC 60079-10.

The intelligent line-type heat detector works perfectly, even under the most difficult conditions. Whether the fully automatic monitoring of large areas, resisting corrosive gases, extreme humidity and high temperatures, or differentiating between false alarms and real danger – the list of requirements for a state-of-the- art line-type heat detector is both long and detailed.

The integrated ADW 535 line-type heat detector combines a proven functional principle with the latest developments in sensor and processor technology.

A sensing tube filled with normal air is installed in the area to be monitored. A fully electronic pressure sensor permanently records the pressure in the sensing tube. This is monitored constantly in the processing electronics and compared with the alarm criteria. Diverse setting options are offered directly on the device via EasyConfig or using the comfortable ADW Config tool for perfect adaptation to existing environmental conditions. The Dynamic Heat Watch (DHW) technology ensures that a brief temperature increase caused by the ambient conditions does not result in a false alarm.

The system is optimally protected against failures: if there is suspicion of a leak in the sensing tube, a monitoring device generates a defined overpressure in the sensing tube at specific intervals. If the registered pressure deviates from the saved default value (e. g. due to a leak or crushed tube), then the computer immediately triggers a fault.

Thanks to the extremely tough sensing tube, the SecuriSens ADW 535 can be deployed in many applications where conventional fire detectors do not work. With its long service life and maintenance-free design, the ADW 535 is also ideal in applications where the detection properties must remain constant over the entire product service life.
