Product Highlights
- Universal media compatibility for seamless operation with both liquids and dry bulk solids, regardless of conductivity, including adhesives, oils, slurries, and powders
- Wide electrode selection offering rod or rope-style electrodes up to 6 meters in length, with options for uncoated, FEP, or PFA-coated variants to suit a range of materials and tank geometries
- Available in high-temperature (up to 572°F / 300°C) and explosion-proof configurations (ATEX Zone 0 and Zone 20 certified), making it suitable for chemical plants, fuel storage, and mining operations
- Flexible mounting options supports vertical, horizontal, or slanted installations with threaded (NPT, G), or tri-clamp connections for sanitary and industrial applications
- Supports NPN, PNP, and NAMUR open collector outputs, allowing integration with standard and safety-rated control systems across industries
- Integrated green and orange LEDs offer real-time visual feedback for operational status, diagnostics, and setup verification
- All wetted parts made from stainless steel (AISI 304/316L), with industrial-grade insulation options such as PTFE and PPS + GF40 for high resistance to chemicals and heat
- No tools or software required—sensor sensitivity, switching mode, and hysteresis can all be configured using the included magnetic pen
- Depending on electrical connection type, the P420 provides IP67 or IP68 protection against water and dust ingress, making it suitable for both indoor and outdoor use
- NAMUR outputs and explosion-proof ratings ensure safe use in hazardous areas, compliant with EN 60079 standards and ATEX 0140X certification
