Abstract
A device for monitoring a pneumatically-actuated alternating linear displacement pump is provided, and a system for monitoring a pneumatically-actuated alternating linear displacement pump is provided, which include elements for sensing pneumatic pressure, elements for transmitting a signal representative of the sensed pneumatic pressure, and elements for managing the pneumatically-actuated alternating linear displacement pump in accordance with the transmitted signal representative of the sensed pneumatic pressure.
Claims10
A monitoring device for monitoring a pump for pumping a liquid or pasty product, for malfunctions in the pump, the pump being actuated by a reciprocating linear displacement pneumatic motor having a piston and two chambers, whereby pressurized air is alternatingly directed into one of the chambers in order to raise or lower the piston, while exhausting air expelled from the other chamber, the monitoring device comprising:
- a sensor sensing a pneumatic pressure over time within one of the chambers of the reciprocating linear displacement pneumatic motor;
- a transmitter transmitting a signal representative of the pneumatic pressure sensed by said sensor to a managing device;
- and
- the managing device comprising a clock or counter that generates a timing chart covering at least one piston cycle based on the signal transmitted by said transmitter, the timing chart being representative of a change in the pneumatic pressure sensed by said sensor, and thus representative of a frequency of the piston, the timing chart indicating either that the pump is working in a regular periodic manner or that it is working in a non-periodic manner signifying a defect in an operation of the pump.
