The ExDetector HC 150 detector is used to measure the current concentration of explosive gases and vapors.
The ExDetector HC 150 can be used to detect explosive gases and vapors in the measuring range from 0 to 100 % LEL. The measuring principle is based on catalytic combustion (heat tinting). This measuring principle can be used to monitor a large number of gases, e.g. hydrogen and hydrocarbons.
It also meets all the criteria for use in Ex zone 2 and in areas of functional safety in accordance with SIL-1.
Variant for duct installation and high ambient temperatures:
The ExDetector HC 150-K detector was specifically designed for installation in ducts and features a transmitter that is separate from the sensing head.
This special combination is used to measure the current concentration of explosive gases and vapors in a pipe network.
| Measuring head | gas | Measuring range |
| Pellistor sensors | ||
| Flammable gases – of which tested | 0 – 100% LEL | |
| Tested gases (in air) | ||
| Methane | 0 – 100% LEL | |
| Ethane | 0 – 100% LEL | |
| Propane | 0 – 100% LEL | |
| Hydrogen | 0–100% LEL | |
| n-pentane | 0 – 100% LEL | |
| n-hexane | 0 – 100% LEL | |
The following gases can be monitored with the ExDetector HC 150.
This detector is not suitable for monitoring solvent vapors.

The ExDetector HC 150-K detector was specifically designed for installation in ventilation ducts and features a transmitter that is separate from the sensing head. It can be mounted on ventilation duct shafts using a mounting flange to detect hazardous gas concentrations inside the ducts.
This special combination is also used to measure the current concentration of explosive gases and vapors in a pipe network.
A particularly unique feature of this combination: the remote sensor in the measuring head of the HC 150 K sensor module, our “duct sensor”, can be used in an environment up to max. 80 degrees Celsius inside the duct, while the more temperature-sensitive components (up to 55 degrees Celsius) perform their duties outside these critical temperatures. A unique solution for problematic temperatures and atmospheres.
