Diaphragm Level Switches

Diaphragm point level sensors detect material levels through mechanical deflection of a flexible diaphragm caused by pressure from solids, powders, or granular media. When the media reaches the sensor diaphragm, the pressure-induced deflection triggers a microswitch, activating alarms or control systems. Particularly effective in handling abrasive, sticky, or heavy bulk materials, diaphragm sensors are widely used in bins, silos, hoppers, and chutes across cement, aggregate, mining, agricultural, chemical, and food industries. Rugged construction using robust materials like stainless steel, rubber, or abrasion-resistant polymers ensures long-term reliability and durability under severe environmental conditions. Diaphragm sensors provide reliable level indication, require minimal maintenance, offer easy installation, and effectively integrate into automated industrial control systems.
