    摘要： A sensor used to control a peristaltic pump includes a housing, a tubing channel extending through the housing, a pressure sensor adjacent the tubing channel to measure an internal pressure of a tubing set inserted into the tubing channel, and a temperature sensor adjacent the tubing channel to measure a temperature of a wall of the tubing set. The sensor can also include a bubble sensor adjacent the tubing channel to detect bubbles within a fluid flowing through the tubing set. The sensor can be used to control a peristaltic pump. For instance, the peristaltic pump can include a microprocessor that can determine the internal pressure of the tubing set from an output of the pressure sensor and compute therefrom a pump factor required to maintain a given flow rate of the fluid flowing through the tubing set. It can then adjust a pump factor of the pump head to the computed pump factor.
