Measure pressure pulses on actuators, valves and fittings
Pressure pulses on actuators, valves and fittings are extremely important for monitoring and optimizing the functionality and performance of systems. By measuring these pulses, conclusions can be drawn about the pressure curve, the flow rate and the reaction time of the system. This enables engineers and technicians to detect and rectify potential faults at an early stage. In addition, regular measurements allow maintenance and repair intervals to be better planned, resulting in increased operational reliability and system longevity.
Gases and liquids are moved in piping systems and containers. Pressure peaks can occur due to processes or unauthorized conditions (blockages, quick-closing valves, etc.). The abruptly decelerated medium releases high impulse energies. This energy acts on valves, gate valves and other actuating and control elements and can damage them. Manufacturers of these valves are often required to provide evidence. As the pulse peaks often last only "ms", PLC controls cannot detect either the time or the absolute level of a pressure pulse.
Delphin measuring devices are used here as they have been specially developed for recording and evaluating pressure pulses. They are characterized by their high accuracy, robust design and easy handling. Thanks to their versatile connection options, they can be connected to various actuators, valves and fittings. In addition, Delphin measuring devices Extensive analysis and evaluation options to clearly display the data obtained and provide prepared information. This enables users to react quickly and efficiently to potential problems and optimize their systems effectively
Application highlights of pressure pulse measurement
- Fast and autonomous measured value acquisition for detecting pulse peaks
- Long-term storage with high temporal resolution in the event of an incident
- Connection of any sensors
- Fast and independent evaluation of measurement results with ProfiSignal
- Simple device configuration
Practical example of a pressure pulse measurement
Pressure pulse measurement on control valves
A medium-sized manufacturer of valves has equipped a plant abroad with gate valves. The end customer complains about the valves due to frequent damage. Pressure peaks far outside the specification of the valves are suspected. However, the recordings of the installed pressure sensor with the PLC system do not show these pressure peaks. The manufacturer's service department installs a Delphin LogMessage system parallel to the PLC on the system's pressure sensor. The independent LogMessage recordings over several days were able to prove that the permissible pressures and peak values far outside the specification were significantly exceeded. As a result of the measurement results, the process was adapted with damping elements.
