Performance highlights E101 Intrinsically safe linear position sensor

The E101 is a non-contact linear position sensor designed for intrinsically safe applications in explosive gas or dust environments. Using robust inductive technology, it provides a linear analog output (0.5–4.5 V ratiometric) proportional to the calibrated travel, customizable from 5 mm to 800 mm. The stainless steel body and push rod ensure reliable performance even in harsh environments, with infinite resolution and high EMC immunity.

Usage conditions

Certified for use in hazardous zones (Ex II 1GD, Ex ia IIC T4 Ga, Ex ia IIIC T135°C Da), the E101 sensor withstands temperatures from -40 °C to +80 °C in operation. Sealing options ensure IP67 protection, and installation options include M5 rod eye bearings and body clamps.

Possible applications:

• Valve position monitoring in chemical plants
• Piston stroke feedback in hydraulic systems
• Position tracking in hazardous zone robotics
• Oil and gas pipeline control systems
• Intrinsically safe OEM sensor integration

Advantages

With its long service life, flexibility in configuration, and resistance to harsh conditions, the E101 sensor is ideal for OEM and industrial applications requiring precise and safe position measurement. The unit includes full EMC protection and is supported by Althen’s expert engineering services and galvanic isolation amplifier options (X005).

Other important features:

• ATEX/IECEx/UKEX certified
• Customizable cable/connector options (3- or 5-wire)
• Spring-loaded push rod (extend/retract) options available
• Independent linearity: ±0.25% (up to 450 mm) or ±0.5% (up to 800 mm)
• MTBF: 350,000 hours at 40 °C
