Abstract
A peristaltic pump has a sealed pumphead housing a and a pressure transducer 26 which is responsive to the pressure within the pumphead housing 8. The output 28 of the transducer 26 is processed to provide an indication of the condition of the hose 18 of the pump.
Claims15
A method of monitoring performance of a peristaltic pump comprising a pumphead in which a hose is subjected to a peristaltic action in a housing, the method comprising monitoring pressure fluctuations in a fluid within the housing externally of the hose.
A method of predicting hose failure in a peristaltic pump, comprising a pumphead in which a hose is subjected to a peristaltic action in a housing, the method comprising monitoring pressure fluctuations in a fluid within the housing externally of the hose, analyzing the pressure fluctuations and providing an output representative of the condition of the hose.
A peristaltic pump comprising:
- a pumphead having a housing;
- a hose disposed at least partially within the housing;
- means for subjecting the hose to a peristaltic action in the housing;
- and
- means for monitoring pressure fluctuations within the housing externally of said hoses.
