These pressure sensors have either a portable or permanent configuration Portable systems consist of pressure sensors that are connected to sensing lines running to some or all of the combustors Similar to the portable systems permanent systems provide sensors mounted outside the turbine enclosure The sensors are then connected through sensing lines tubing to each combustor Because of the long sensing lines involved the ability to purge condensation is required There are advantages to this simple Low Cost approach Because the sensors are mounted outside the turbine enclosure the conditions the sensors must endure are relatively mild thus allowing for the use of less expensive sensors with longer life expectancy In addition these sensors can be serviced while the turbine is online Remote Sensors Energy Power Generation ICP Pressure Sensor Model 121A44 n Sensitivity 14 5 mV kPa n Measurement range 345 kPa n 316 stainless steel diaphragm n 1 4 NPT fitting See page 130 for more information ICP Pressure Sensor Model 102M205 n Sensitivity 7 5 mV kPa n Measurement range 690 kPa n 316 stainless steel diaphragm n 3 8 24 UNF fitting See page 130 for more information IECEx IECEx IECEx IECEx IECEx IECEx IECEx IECEx Sensor Enclosure Pressure Sensor or Series 121 Infinite Coil Tube Length approx 10 m visit us online at www imi sensors com 1 716 684 0003 23 Combustion Dynamics Instrumentation
