OPTICAL PRESSURE SENSOR WITH REDUCED MECHANICAL STRESSES

There is described an optical pressure sensor comprising a sensor housing and an optical pressure cell mounted within the sensor housing and dividing the sensor housing into a first fluid space and asecond fluid space. The optical pressure cell comprises a front side exposed to a pressure in the first fluid space and a back side exposed to a pressure in the second fluid space. The optical pressure sensor further comprises a fluid communication arrangement allowing pressure equalization between the pressure in the first fluid space on the front side and the pressure in the second fluid space on the back side of the optical pressure cell. 描述了种光学压力传感器，包括传感壳体和光学压力单元，该光学压力单元安装在传感器壳体内并将传感器壳体分成第流体空间和第二流体空间。光学压力单元包括暴露于第流体空间中的压力的前侧和暴露于第二流体空间中的压力的后侧。光学压力传感器还包括流体连通装置，该流体连通装置允许在光学压力单元的前侧上的第流体空间中的压力与后侧上的第二流体空间中的压力之间的压力均衡。
