Abstract

A pressure sensor (21') measuring the static pressure in the fluid pumped, produces a signal (x21) representing movements of the pump displacer. An electronic unit (22) evaluates the sensor signal. An independent claim is included for the method of monitoring the unit, in which an operational status signal is derived from the fluctuating pressure signal.
