Tuning Fork Level Switch
This tuning fork level switch detects liquid or solid material level via vibration damping when the fork contacts the medium. It provides relay DPDT/SPDT, PNP/NPN, NAMUR and 8/16 mA outputs, with fork temperature from -30 to 150 °C and working pressure up to 2 MPa. Typical applications include level alarm and control in tanks, pipelines and aseptic processes, requiring no adjustment and having no mechanical moving parts.
- Signal output
- Relay DPDT/SPDT, PNP/NPN, NAMUR, 8/16 mA
