A hydrostatic pressure test is used as a proof of strength and leak tightness of containers and pipelines that hold liquids and gases. The procedure and documentation of such a test can be increased in efficiency by using digital pressure gauges. This is particularly …
Applications
Valve actuators: Pressure switch combines control and alarm function
Jing Lyu | ApplicationsHydraulic valve actuators require pressure switches for safe operation. In control cabinets, usually two of these measuring instruments are installed. One switch is used to control the pump for the hydraulic pressure, while the second triggers an alarm if the pressure …
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 …
Injectables: Pressure measurement without risk of contamination
Jing Lyu | ApplicationsInjectables are among the most sensitive products in the pharmaceutical industry. Sterility is essential during production. This is because the active ingredient enters the patient's body directly, bypassing the patient's natural defences. It is therefore important to …
Calculate the flow rate correctly
Michael Lutz | Applications, FlowMillions of cubic metres of liquids or gases flow through the pipes of industrial processes every day. In order to be able to transport, control and monitor these correctly, the flow rate must be calculated beforehand. The flow rate, also called volume flow, is a …
