Silo Level Monitor Breakdown Repairs & Electrical Fault Finding

Dense airborne dust clouds during pneumatic tanker filling scatter acoustic sound waves, causing ultrasonic sensors to register false high-level echoes or lose their signal entirely. We solve this by adjusting signal damping filters or upgrading dusty bulk silos to high-frequency non-contact 80GHz radar transmitters that penetrate dust clouds effortlessly.

Overfill systems use an independent high-high level switch (such as a vibrating tuning fork or rotating paddle) wired directly into a fail-safe pneumatic pinch valve on the fill line. If the silo reaches maximum capacity, the valve snaps shut and triggers an audible siren, preventing over-pressurisation. We test and certify these emergency loops.

Paddle switches fail when abrasive bulk material wears out the shaft seal, allowing dust into the small gearbox, or when dense falling material bends the paddle shaft. We install heavy-duty, torque-adjustable paddle units with protective deflector shields and reinforced shafts.

Yes, we install, wire, and maintain intrinsically safe and explosion-proof (Ex d / Ex t) level transmitters, ensuring full compliance with Australian hazardous area standards for grain, flour, and coal storage.
