Diaphragm

The instruments in this category utilize a flexible diaphragm to detect pressure changes that correspond directly to fluid levels. This mechanical method allows for accurate monitoring of substance depth by measuring the force exerted against the diaphragm surface without the need for complex electronic probes to be submerged in the material.

The primary product available in this collection is the Ultra-Mag™ Explosion-proof Level Switch. This robust device is engineered to provide reliable level detection in hazardous environments where explosive gases or dust may be present, ensuring safety and precision in critical industrial applications.

Diaphragm level sensors are specifically designed for materials that would typically cause traditional sensors to fail, such as abrasive slurries, viscous liquids, or aggressive chemicals. Because the sensor provides consistent feedback without direct internal contact between the sensing mechanism and the medium, it avoids the clogging or corrosion common with other sensor types.

These sensors excel in harsh environments, including chemical storage vessels, slurry tanks, and heavy industrial processing plants. Their sealed design makes them a reliable choice for monitoring levels in outdoor silos or underground tanks where moisture and contaminants are prevalent.

Yes, HK Calibrations offers expert calibration and measurement services to ensure your level switches operate with maximum accuracy and traceability. Our team can help you maintain operational confidence by verifying that your sensors meet industry standards and reduce the risk of overflows or equipment dry-running.

The Ultra-Mag™ model in this collection is specifically rated as explosion-proof, making it suitable for high-risk zones. This rating ensures that the electrical components are contained in a way that prevents them from igniting surrounding flammable atmospheres, which is essential for petrochemical and mining operations.
