DrägerSensor EC Electrochemical Sensors
Faster response – higher accuracy – greater stability – longer life.
Dräger electrochemical sensors offer all these benefits. The robust and
long-life sensors are used for the selective measurement of the smallest
concentrations of toxic gases and oxygen in ambient air.
Long life timeThe 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 weather-related variations in air pressure. A large electrolytic
reservoir and large electrode areas provide sufficient reserves for a
long life time, even in industrial environments.
Comprehensive range of applicationsAll 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.
Ready for use immediatelyAll 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.
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
