摘要： A premixing fuel injector for a turbine engine includes easily replaceable means for monitoring temperature or other conditions of interest in the interior of the injector. The fuel injector includes a guide conduit (70) that penetrates into the injector's interior and has an externally accessible opening (74) for receiving a sensor probe (88) . The probe carries at least one sensor, such as a thermocouple junction (106) , for monitoring temperature or other conditions inside the injector. In one embodiment, the guide conduit has a nonlinear shape and the probe shank (92) is sufficiently flexible to follow the contour of the conduit and sufficiently rigid to overcome any insertion resistance that the conduit might offer. The flexibility of the shank (92) may vary longitudinally to enhance insertability of the probe into the conduit. The probe is longitudinally oversized relative to the conduit so that when the probe is correctly installed, a sensor element positioned at the probe tip (93) contacts the closed, distal end (84) of the conduit to improve the sensor's responsiveness to changing conditions inside the injector. The probe shank may also buckle slightly and press against the internal sidewall of the conduit to prevent excessive shank vibration.

摘要翻译： 用于涡轮发动机的预混燃料喷射器包括用于监测喷射器内部的温度或其他感兴趣条件的易于替换的装置。 燃料喷射器包括穿入喷射器内部的导向管道（70）并具有用于接收传感器探头（88）的外部可接近的开口（74）。 探针携带至少一个传感器，例如热电偶接点（106），用于监测喷射器内部的温度或其他状况。 在一个实施例中，引导导管具有非线性形状并且探针柄（92）具有足够的柔性以遵循导管的轮廓并且具有足够的刚性以克服导管可能提供的任何插入阻力。 杆（92）的柔性可以纵向变化以增强探针对导管的可插入性。 探针相对于导管纵向过大，使得当探针正确安装时，位于探针尖端（93）处的传感器元件接触导管的封闭远端（84），以改善传感器对内部条件变化的响应 注射器。 探头柄也可以轻微弯曲并压靠导管的内侧壁以防止过度的柄振动。
