Advantages of in-situ calibration using the example of pressure switches
Jing Lyu | ApplicationsIn-situ calibration of measuring instruments is carried out in numerous industrial processes. The advantages are obvious: The instruments remain installed, so the process does not have to be opened. In this way, plant operators reduce the time and costs involved in …
Time settings in a pressure switch and their purpose
Imane Nahid | Know-howTime settings can be made for each electronic pressure switch. Through these, users clean the measurement of the pressure profile in the application and the display of the measured value of any insignificant “outliers”. As a result, you receive a smoothed result …
Pressure switch for safe operation of food silos
Jing Lyu | ApplicationsPressure switches in food silos make a significant contribution to detecting overpressure in good time and safely preventing it. A manufacturer of such elevated vessels uses the model MA mechanical pressure switch for this task. One special property tipped the scales …
Differential pressure switches ensure safe filter operation
Jing Lyu | ApplicationsDifferential pressure switches take on central tasks within monitoring and control. A manufacturer of filter systems for the process industry uses the WIKA model DE switches with an attached valve manifold for these functions. The decision in favour of this solution …
