LNZ 450 series
for noxious environments
LNZ 450 series dust explosion protected compact sensors are built to control, monitor and record air flows in Ex zone 22. These devices are needed by Timber industry as they have to strictly maintain explosion protection standards since 2006. Thus air flow controllers are needed to monitor and control exhaust systems closely It is equipped with an one switching output and an integrated LED display that triggers of an alarm on occurrence of flow change in the exhaust system. A freely adjustable alarm threshold with detection range of 0.5...30 m/s. Suited for temperature range between -10 and +60 °C these controllers are obtainable in different fitting lengths which make possible installation with wide variety pipes.
