CG568 Tuning-Fork Liquid Level Switch – G1 Thread, 316 SS Fork, DPDT Relay, 24 VDC

Description

Vibrating tuning-fork point level switch for liquids. Piezo crystals drive the fork at its natural frequency; when liquid covers the fork the frequency changes and the relay switches. No moving floats, so it is not stopped by turbulence, foam or buildup the way a float can be. This listing is the standard G1-thread version with 24 VDC supply.

Typical uses in oil and gas

• High-level alarm on produced-water, oil and chemical tanks, wired to the RTU or a pump stop
• Low-level / run-dry protection for transfer and injection pumps
• Sump and containment liquid detection

Fail-safe mode (high or low) is set on the unit. Check that the liquid density is above 0.6 g/cm³ and that the process pressure stays below 1 MPa. This is the standard version, not an explosion-proof version.
