According to the new, stricter provisions of the German Ordinance on Hazardous Substances, laboratories, schools and industrial facilities which work with aggressive chemical materials must be equipped with special exhaust air systems. In accordance with the DIN 1946-7/7-2009 standard the air fl ow must be monitored directly and electronically. Monitoring the ventilating fans is not enough, because blockage or malfunctions cannot be detected in this way
A company, which specialises in air technology, equipment and environmental technology as well as plastic processing, needed air fl ow sensors for their exhaust systems. Because the exhaust systems were to be used with chemically aggressive materials in particular, air fl ow sensors which are resistant to these aggressive materials were needed. They also had to be robust and easy to install in the exhaust duct.
On account of the technical specifi cations of the sensor, which also had to be resistant to sulphur-containing exhaust from galvanic baths, the company chose the Proxitron FKM 130.83 air fl ow sensor. Unlike mechanical sensors, where sensing elements (membranes or wind vanes) move and become unusable due to dirt, grease or emulsions, Proxitron air fl ow sensors are protected from wear thanks to their calorimetric functioning principle and the integrated electronics into the plastic housing.
All Proxitron air fl ow sensors feature easy installation and maintenance-free function. The 230 V AC voltage used in the system is used directly for operation and as a switching signal. An additional DC auxiliary voltage or an external evaluation device is not necessary. If the fl ow rate falls below the minimum level, the sensor interrupts the output signal. The adjustable set fl ow rate can thus give an early warning if the fl ow rate is dropping below the minimum fl ow and initiate the timely servicing of the exhaust system.
An assembly fl ange is included in the scope of supply. Alternatively suitable clamps or a M32-cable screw connection can be used for pressure-resistant assembly.
