Ultrasonic, Tuning Fork & RF Capacitance

Vibrating tuning fork level switch for liquids and solids. No moving parts — the fork vibrates at its natural frequency; when submerged, the frequency shifts and triggers the output. Unsurpassed reliability where mechanical linkages and moving parts are not acceptable.

Approvals: FM, UL, CSA

Miniature direct load vibrating tuning fork level switch. Compact design for tight installations. Suitable for liquids and solids in tanks and vessels.

Approvals: FM, UL, CSA

Ultrasonic gap level switch for liquids. Transmitter and receiver are mounted across a small gap; liquid presence in the gap interrupts the ultrasonic beam and triggers the output. No moving parts, no contact with the process fluid.

Approvals: FM, UL, CSA

Vibrating probe level switch for bulk solid measurement. The probe vibrates at its natural frequency; when buried in solids, the vibration is damped and the output switches. Suitable for powders, granules, and bulk solids.

Approvals: FM, UL, CSA

RF capacitance point level switch with driven shield circuitry that ignores conductive material build-up on the probe. For conductive and non-conductive liquids, granular materials, foams, pastes, slurries, and interface applications.

Adjustable RF capacitance level switch with field-selectable low or high level failsafe modes. Adjustable relay time delay to prevent chattering in turbulent applications.

Continuous RF capacitance level transmitter providing a 4–20 mA output. Compatible with any Jerguson insulated or driven shield level sensing probe.
