4.32 Pressure/Temperature Sensor
4.32.1 Pressure/Temperature Sensor Function
The suction, interstage, and discharge pressure/temperature sensors are used to inform the compressor of the
operating pressures and temperatures at their respective locations. These values are used to calculate pressure
ratios, saturated temperatures, superheat and the location within the operating envelope where the compressor is
running.
Figure 4-270 Pressure/Temperature Sensor
4.32.2 Pressure/Temperature Sensor Connections
The suction pressure/temperature sensor is secured to the IGV, above the suction port.
The discharge pressure/temperature sensor is secured to the compressor housing, above the discharge port.
The interstage pressure/temperature sensor is secured to the Interstage Pipe.
Refer to Figure 4-271 Pressure/Temperature Sensor Connections (All TTS/TGS Compressors) and Figure 4-272
Pressure/Temperature Sensor Locations (TTH/TGH) on page 246 for the location of the sensors.
