Abstract

The invention relates to a system for producing a test pressure for pressure-sensing devices, in particular for pressure gauges, measuring transducers and pressure monitors, consisting of a pressure pump and a pressure-regulating valve, attached to this pressure pump, as well as a test connection, attached to the outlet of the pressure-regulating valve, for the respective pressure-sensing device, in which arrangement a pressure transducer (9) is attached between the outlet of the regulating valve (3) and the test connection (8) for converting the pressure value received at the outlet of the regulating valve into an electrical actual-value signal, and the actual-value signal is fed to a comparator together with an electrical desired-value signal corresponding to a certain pressure value, and the desired/actual value differential signal controls the pressure-regulating valve in such a way that the desired/actual value difference becomes zero. <IMAGE>
