Ansi Engineers

• Vibronic (Tuning Fork) Level Switches – Detect level in liquids reliably and maintenance-free using vibrating fork technology — not influenced by foam, turbulence or media changes.

• Conductive Level Switches – Compact switches suitable for conductive liquids, where electrical conductivity changes indicate level points.

• Rotary Paddle (Paddle Switch) – Robust mechanical switches ideal for bulk solids and powders, detecting material presence by paddle blockage.

• Float / Electromechanical Switches – Simple and cost-effective switches using float action for basic liquid level alarms.

✔ Point Level Detection: Detects high, low or overflow conditions with reliable switch outputs.
✔ No Calibration / Maintenance-Free Designs: Many models operate without calibration and contain no moving parts (vibronic) for long service life.
✔ Wide Process Conditions: Designed to work over wide temperature and pressure ranges depending on model and media.
✔ Robust Construction: Materials like 316 L stainless steel resist corrosion and are suitable for hygienic and industrial environments.
✔ Easy Installation: Simple mounting options (threads, flanges, hygienic connections) and plug-and-play operation on many units.
✔ Enhanced Diagnostics: Some switches support digital communication and continuous diagnostics for safety and process insights.
