Performance highlights

The G133 is a rugged and intrinsically safe linear position sensor optimized for mid-stroke measurement ranges in explosive environments. Using wear-free inductive technology and the EX08 electronics module, it ensures stable performance and long sensor life. It provides a linear analogue output (0.5–4.5 V ratiometric) across calibrated travel lengths between 51 and 100 mm.

Usage conditions

Ideal for OEMs, automation integrators, and process engineers working in hazardous gas areas (Zones 0, 1, 2), the G133 is certified to CSA standards and operates from -40°C to +80°C. The sensor is sealed to IP65 or IP67 depending on the selected connector or cable configuration.

Typical applications:

• Valve position feedback in ATEX areas
• Petrochemical test rigs
• Hazardous area actuator control
• Oil & gas automation
• Short-to-mid-range EX displacement feedback
• OEM systems with limited space

Benefits and differentiators

With a short overall body length and compact Ø35 mm housing, the G133 offers high-accuracy sensing with minimal installation footprint. It can be supplied with a wide range of mounting (flange, rod eye, clamps) and tip options (spring, dome, magnetic) for full mechanical flexibility.

Technical highlights:

• Independent linearity: ±0.25% FSO (±0.1% on request)
• Resolution: Infinite
• Frequency response: >10 kHz
• EMC compliant: EN 61000-6-2, -6-3
• Shock: 40 g | Vibration: 10 g
• MTBF: 350,000 hours @ 40°C
• Output: 0.5–4.5 V ratiometric (EX08 electronics)
• Supply: 5 V (10 mA nominal)
• Load resistance: ≥5 kΩ
