Highlights

The DrägerSensor® ... DQ detects flammable gases and vapours such as hydrogen. Due to the double-detector compensation method, the catalytic sensor is particularly long-term stable. The wire mesh at the gas inlet serves as a flame barrier. So it ensures explosion protection at the same time short response time.

The catalytic bead principle

The DrägerSensors ... DQ are based on the catalytic bead detection principle. The most important component are the hot, catalytically active pearls on platinum coils (pellistors). These pellistors burn the gas and additional heat of reaction is creat … More information

DrägerSensor® PR M DQ

PR stands for poison resistant. The pellistors of the DrägerSensor PR M DQ have a longer service life under the influence of poisonous substances. The sensor has a metric thread (M) on the back.

DrägerSensor® PR NPT DQ

The DrägerSensor PR NPT DQ also withstands poisoning substances for a long time. This sensor is equipped with a NPT thread on the back.

DrägerSensor® HT M DQ

The DrägerSensor HT M DQ can be used at ambient temperatures of up to 155 ° C and is also approved accordingly (HT = high temperature). This sensor also has a metric thread.

DrägerSensor® LC M

​LC stands for >low concentration<. The DrägerSensor LC M detects very low gas concentrations in the measuring range from 0 to 10% LEL. This is possible by a special arrangement of the PR pellistors, as well as an amplifier electronics. The sensor ha … More information

DrägerSensor® LC NPT

​The LC NPT sensor also detects gas concentrations in the measuring range of 0 to 10% LEL. It is equipped with a NPT thread.
