ExDetector HC 100 / HC 100 K
The ExDetector HC 100 sensor measures the current concentration of explosive gases and vapors.
The ExDetector HC 100 detects flammable 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 (other gases on request).
The ExDetector HC 100 is a versatile sensor and is designed in particular for use in Ex zone 1 and in overall safety systems that are classified according to SIL-1.
A type examination certificate for the measuring function in accordance with Directive 2014/34/EU is available. A measuring function certificate BAM 03 ATEX 0003 X is also available.
Variant for duct installation and high ambient temperatures:

Description
The ExDetector HC 100 sensor measures the current concentration of explosive gases and vapors.
The ExDetector HC 100 detects flammable gases and vapors in the measuring range from 0 to 100 % LEL. The measuring principle is based on catalytic combustion (heat tinting/pellistor). This measuring principle can be used to monitor a large number of gases, e.g. hydrogen and hydrocarbons.
The ExDetector HC 100 is a versatile sensor and is designed in particular for use in Ex zone 1 and in overall safety systems that are classified according to SIL-1.
A type examination certificate for the measuring function in accordance with Directive 2014/34/EU is available. A measuring function certificate BAM 03 ATEX 0003 X is also available. The standard device goes by the name of ExDetector HC 100 M.
ExDetector HC 100 T+K – especially for duct installation. Suitable for high temperatures.
The sensor combination ExDetector HC 100-T (sensor electronics) and HC 100-K (sensor module) has been specially developed for machine and duct installation. The ExDetector HC 100 K has a gas measuring head that is separate from the sensor module and can be mounted on duct shafts using a mounting flange in order to detect hazardous gas concentrations inside.
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 100 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 and type-tested solution for problematic temperatures and atmospheres.
Functionality of the ExDetector HC 100 within a gas warning system:
The ExDetector HC100 series sensors in combination with evaluation systems have the following functions:
- Measurement and display of the current concentration of explosive gases and vapors
- Monitoring or warning of these gases
- Triggering of protective measures:
– Technical: The increase in concentration is counteracted (fans; shutdowns….)
– Organizational: Visual and acoustic messages - A gas warning system consists of the following components:
– Sensor
– Evaluation system
– Controllable devices such as fans, warning signs and solenoid valves
Accessories for the ExDetector HC 100:
- Test gas set
- Calibration gases
- Control unit type Calibrationbox-i
- Evaluation devices
- Mounting bracket
- Remote gassing adapter FBA2018
