Optical dissolved oxygen sensor for safeguarding sensor membrane

摘要

sensor film can be prevented or destroyed by the impact of foreign objects attached the proposed optical dissolved oxygen sensor that protects the membrane sensor. The sensor of claim 1 for generating a purple , and blue light emitting unit , the sensor generates a signal light and a fluorescent body comprising a light-receiving portions receiving a second light-emitting portion and the fluorescent signal generated by the red and the support frame for receiving the sensor film is made of a fluorescent dye and a sensor comprising a film portion , and a sensor cap sensor film portion is inserted . ;
