Product Overview

The HeavyDuty-LVDT-500 is a high-reliability industrial linear sensor engineered for demanding process automation and safety-critical environments. As a precision linear probe, it delivers robust, contactless position measurement across a full 0–500 mm stroke range with exceptional linearity (<±0.25% FS) and long-term stability. Designed specifically for hazardous areas, this ATEX certified linear probe meets EN 60079-0 and EN 60079-11 standards for Zone 1 (gas) applications — making it ideal for oil & gas, chemical processing, and pharmaceutical manufacturing where intrinsic safety is non-negotiable.

Unlike conventional potentiometric or Hall-effect sensors, the LVDT-500 leverages transformer-based electromagnetic principles to ensure infinite mechanical life, zero hysteresis, and immunity to vibration, shock, and EMI. Its 4–20mA analog output provides noise-resistant, industry-standard signal transmission over extended cable runs — eliminating the need for additional signal conditioning in distributed control systems (DCS) or PLC integrations.

Key Features

• True contactless measurement — no wear, no friction, >100 million cycle lifespan
• Integrated 4–20mA current loop output with 24 VDC supply (2-wire)
• Temperature-compensated electronics (-40°C to +85°C operating range)
• Stainless steel core rod and reinforced PTFE-coated guide bushing for harsh environments

Technical Specifications

Applications

This industrial linear sensor is widely deployed in critical infrastructure requiring precise, fail-safe position feedback: hydraulic cylinder monitoring in offshore drilling rigs; valve stem positioning in ATEX-compliant petrochemical plants; actuator feedback in explosion-proof conveyor systems; and level sensing in pressurized reactor vessels. As a ruggedized 4-20mA position sensor, the HeavyDuty-LVDT-500 ensures continuous, drift-free operation where reliability directly impacts personnel safety and regulatory compliance — reinforcing its role as a cornerstone component in mission-critical industrial automation.
