Extracting the benefits of remote mounting
The SERVOTOUGH FluegasExact 2700 is designed to measure oxygen and combustibles in the most demanding combustion environments, including process boilers, thermal crackers, incinerators and furnaces.
Sensor head mounting is a critical design consideration on any process, with implications for long-term measurement performance and maintenance requirements. Direct mounting – with the sensor head mounted on the measurement point and secured to a process flange – is seen as the standard approach.
However, remote mounting offers many benefits, particularly in situations where the flange mount is too hot for equipment, or the location is difficult to access or dangerous for personnel.
In remote mounting, the sensor head is situated on a panel or cabinet away from the process, and is connected to the sample point via an insulated sample line.
The sample-in and exhaust lines are heated to minimize the risk of sample gas condensation. This makes maintenance much easier, with no need for a technician to climb high up a furnace to carry out repairs or basic troubleshooting checks.
The ease of access saves on downtime and overheads. Technicians do not have to worry about heat fatigue or the unit being in a hazardous area, since everything is at ground level in an area with reduced health and safety risks.
