Hydrostatic pressure test with a digital pressure gauge
| Jing Lyu | Applications, PressureA 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 …
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 …
Ignition protection type Ex i for pressure measuring instruments with battery operation
| Jing Lyu | Pressure, ProductsWhich ignition protection type is suitable for battery-operated pressure measuring instruments, which are increasingly being used in combination with a radio unit? WIKA has clearly answered this question for its portfolio: “Ex i”, i.e. intrinsic safety. This …
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 …
