1 DrägerSensor EC Electrochemical Sensors Sensor for Fixed Gas Detectors Faster response higher accuracy greater stability longer life. Dräger electrochemical sensors offer all these benefits. The robust and longlife sensors are used for the selective measurement of the smallest concentrations of toxic gases and oxygen in ambient air. ST

Dräger electrochemical sensors offer all these benefits.

2 02 DrägerSensor EC Electrochemical Sensors Benefits Long life time The use of resistant plastics, such as PTFE, and the purest catalysts make it possible to achieve a long, wear-free measurement function over long periods. A patented internal pressure compensation mechanism compensates adverse environmental influences from changes in humidity, temperature expansion and weatherrelated variations in air pressure. A large electrolytic reservoir and large electrode areas provide sufficient reserves for a long life time, even in industrial environments. Ready for use immediately All sensors are factory calibrated, and these values are saved in the internal, electronic memory. This means that sensors in the field can be used immediately. The high-quality technical construction guarantees a long stability and low, age-related drift. Comprehensive range of applications All sensors have an internal temperature sensor. Between -40 C and +65 C, the temperature influence is compensated to zero, and the sensitivity is automatically adjusted. The internal pressure compensation allows the transmitters to be used during extreme low pressure, and high atmospheric pressure. In combination with exchangeable, selective filters, it is possible to reduce the influence of disruptive cross-sensitivities. Performance Low detection limits Optimised selectivity Excellent accuracy of measurements Fast response High stability Wide range of applicational areas Long life time Comprehensive self-diagnosis options No position dependency Advanced sensor technology It is possible to choose between oxygen sensors for partial pressure measurement or volume percent measurement. Acid gas sensor AC with unlimited life time, due to refillable electrolyte. Sensors with organic electrolyte for detection limits in lower ppb range
