Table type bioreactor controller

Abstract

The invention discloses a table type bioreactor control instrument, belongs to the technical field of control instruments, and aims to solve the problems that a certain deviation exists between the rotating speed of a pump shaft and a set rotating speed after the table type bioreactor control instrument is used for a certain time, and equipment for accurately controlling the rotating speed of the pump shaft so as to control the material pumping speed does not exist in the current market. Comprising a control circuit, a motor driving circuit and a peristaltic pump, the output end of the control circuit is connected with the input end of the motor driving circuit, the output end of the motor driving circuit is connected with the input end of the peristaltic pump, and a pump shaft of the peristaltic pump is provided with a data collector for collecting rotating speed data of the pump shaft. The rotating speed of the pump shaft of the peristaltic pump is detected through the data collector, the control circuit compares detected data with set data, and therefore the motor driving circuit is controlled, the rotating speed of the pump shaft of the peristaltic pump is made to be the same as the set rotating speed, and the pumping precision is guaranteed.
