Probe-Type Online Biomass Detection Apparatus Capable of Being Subjected to High-Temperature Sterilization

A probe-type online biomass detection apparatus capable of being subjected to high-temperature sterilization, comprising an optical fiber probe, a light source and light receiving sensor module, and a signal processing module, wherein

• the light source and light receiving sensor module comprises a light source, and a light receiving sensor;
• and
• measuring light is emitted from the light source to a measurement area through the optical fiber probe, cells in the measurement area has a reflection action to the light, the reflected light returns to the optical fiber probe, and reaches the light receiving sensor through the optical fiber probe, a light intensity signal received by the light receiving sensor directly reflects the cell concentration, and the signal processing module calculates the cell concentration according to the light intensity signal received by the light receiving sensor.
