Industrial Applications

1. Hazardous Area Position Monitoring in Chemical Processing

This sensor is ideal for reliable, non-contact position detection of metallic components, such as valve positions or gate closures, within chemical processing plants. Its NAMUR output ensures intrinsic safety when paired with an approved switch amplifier, preventing ignition in environments with flammable gases or dusts. The stainless steel housing and IP66/67 rating offer high resistance to corrosive substances and frequent washdowns.

Problem Solved

Prevents ignition hazards in potentially explosive atmospheres by providing intrinsically safe position sensing for critical equipment, while its robust construction ensures durability in harsh chemical environments.
