The Set consists of the following components which can be selected as options:
The basic version includes the FIDAMAT 6 in a purged sheet-steel protective housing for use in hazardous areas of Zone 2. The monitoring unit for monitoring the volume flow of the purging air and observation of the pressure limits in the protective housing is included in the delivery.

In a further version, the basic system can be ordered completely assembled on a mounting plate with dimensions 1 000 x 2 000 mm (W x H). This version additionally provides the complete combustion air preparation device, and is supplied with complete wiring and piping for installation in an analysis cabinet or standard protective cabinet.

The system can be optionally ordered completely ready for connection in a standard protective cabinet made of sheet-steel or FRP.
With all versions, the gas connections on the process side can be ordered with metric or Imperial dimensions.
The combustion gas supply can be ordered optional to the various versions.
The components are fitted on a mounting plate, and include:
The pressure of the combustion gas cylinder is monitored by a pressure switch. If the set limit is fallen below, automatic switchover to the replacement cylinder is carried out. An alarm is triggered at the same time to signal that it is necessary to replace the cylinder. The continuous supply with combustion gas means that interruption-free operation of the equipment is guaranteed.
Combustion and calibration gases do not belong to the scope of delivery. These must be ordered separately as required.
The sample gas is supplied to the FIDAMAT 6 at pressure, and passes via an anti-clogging fused silicone restrictor to the flame ionization detector.
Hydrogen (H2) is used as combustion gas. In the basic version, the FIDAMAT 6 is installed in an IP54 housing suitable for EEx(p) which is permanently purged with instrument air.
Purging prevents the formation of an explosive atmosphere in the housing should large leaks occur or if the combustion gas line breaks. To this end, any combustion gas released must be diluted down to a concentration < 25 % of the LEL. This requirement in accordance with DIN EN 60079-2 is achieved by permanent purging with instrument air at a flow rate of approx. 1 200 l/h.
The purging results in an overpressure in the protective housing. Therefore, any gas vapors which might occur occasionally cannot penetrate into the housing. The overpressure in the protective housing has a setpoint of 10 mbar. The monitored limits are between 0.8 and 15 mbar.
The purging flow rate for the protective housing and the set pressure limits are monitored.
In the event of a fault:
The pressure of the combustion air supply for the FIDAMAT 6 is monitored by a pressure switch whose switching point is set to approx. 200 mbar below the supply pressure. If the pressure drops as a result of a leak or a break in the combustion gas line, the combustion air supply is switched off by a solenoid valve outside the housing.
Gases or gas mixtures that are frequently or continuously flammable must not be introduced into the FIDAMAT 6 gas analyzer.
The exhaust air and exhaust gas of the FIDAMAT 6 must be routed into the non-hazardous area.
Following installation and maintenance work affecting the gas paths, a leak test must be carried out as described in the manual.
