Accurate Detection provides a wide range of Hycontrol vibrating probe level switches for liquid and solids applications. The operating principle is the same for all Hycontrol vibrating probe level switches.
A piezo-electric crystal is used to force a blade to oscillate at its fundamental frequency. When the blade comes into contact with the process medium, the oscillation changes – the electronics sense this and causes the unit to switch.
Hycontrol produce two series of vibrating level switches:
Hycontrol Tuning fork Vibrating level switches for liquids
The TF and MTF tuning fork series are of rugged and compact design. Wetted parts are 316 St/St with options for special coatings for extremely corrosive applications. Process connections are threaded, flanged or Tri-Clover sanitary depending on the application.
All Hycontrol tuning fork level switches have a visual indication of switch status and onboard sensitivity adjustment. EEx and I.S options are available.
Hycontrol Vibrating Level Switches for Solids
The Diamond single blade design is specifically for dry products ranging from stone aggregates and heavy materials such as cement, to very low density materials like cornflakes and fine powders like flour.
A single blade diamond design provides strength, sensitivity and prevents build up on the blade. Process connections include threaded or flanged options. All Hycontrol Diamond level switches have a visual indication of switch status and onboard sensitivity adjustment.
Dust approval option for zone 20/21 and 22. SIL 2 approval.
