A low cost optical on‐line biomass sensing system for fermentation processes is presented in this paper. The calibration curve of the sensor obtained by using cell cultures in tap water revealed a linear profile in the range 0.1–4.0 g/L. The sensor was shown to have a fast response time and was insensitive to the natural light. A good reproducibility was obtained between the optical sensor and cell dry‐weight method values.
