TECNOCONTROL AN401EN2 Suction detection unit for nitrogen dioxide 30ppm

Suction detection unit for nitrogen dioxide 30ppm

Unit designed to provide a control and prevention system for dangers deriving from the presence of toxic atmospheres in all applications where due to the effect of forced ventilation or temperatures different from those typically environmental, such as ovens, refrigerated rooms, combustion chambers, not it is possible to perform a traditional implant. Necessary for the protection of many work environments due to the risk of toxicity, it is often used for industrial process controls. Depending on the gas to be detected, the sensors used can be of the catalytic combustion, electrochemical or infrared type, housed in a CESI Ex-d-IIC-T6 certified explosion-proof sintered filter. The system is also equipped with a solenoid valve and a timer, configured to allow the sensors to be washed with pure air at the end of each analysis cycle. The models available are with one, two, three or four sensors, all of which are different from each other. The suction units of the AN400 family are equipped with advanced programming electronics, which can be used via the keyboard on the front and a large display that indicates sensor readings in real time. Programming allows you to obtain the necessary alarms at the complete discretion of the user, to perfectly adapt to the needs of the systems. The alarm outputs consist of freely programmable potential-free relays and a 4-20mA output for each sensor installed
