Thermal flow switch LNZ 450 series

for aircompactfor 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. EGE offers thermodynamic flow controllers without moveable parts, which means they are robust and resistant to soiling. Controllers for fluids such as water, glycol mixtures or chemicals are as much part of the product range as sensors for gases such as air and carbon dioxide. Intrinsically safe sensors based on ATEX for explosive and hazardous areas are also available. Additional variations consist of high temperature sensors up to 160 °C, special sensors made from such materials as Hastelloy, Monel, titanium and tantalum with high resistance to chemicals, and programmable flow sensors with digital displays. The flow controllers are either screwed into the side of the pipe or added to the line itself in the form of inline sensors.
