Datasheet

Product info

Explosion-proof inclinometer based on Vigor’s patented tilt technology and special EX protections delivers highly accurate tilt data with high safety and durability.
It features robust cast aluminum housing and professional connector/cable/protection/grounding assemblies according to ATEX/IECEx.

Key capabilities

±0.02%FS linearity
±0.005° Offset
Performance verified for offset, repeatability, hysteresis, and turn-on repeatability
Advanced algorithms drastically reduce cross-axis error and improve true tilt accuracy
Greatly reduced errors when the real tilt direction differs from the sensor’s sensitive axis
Short-circuit, transient voltage, overheat, and transposition protection for industrial environments

Applications

Level measurement in harsh environments (petroleum, chemical industry, natural gas, flammable and explosive), precision angle measurement, and industry & lab equipment leveling.
Attitude monitoring, angle measurement and alarming of buildings and structures in gas explosion-proof zone 1 & 2 and dust explosion-proof zone 21 & 22.
Attitude monitoring in harsh environments such as offshore drilling platforms, large flammable/explosive storage, complex geology, and dangerous vehicles/vessels; also for monitoring detection equipment in dangerous areas.
