L12J0101 I.S Inclinometer Module IECEx TSA 23.0005X with Marking Ex ib I Mb

Type L12J Ex ib I Mb Machine Mounted Inclinometer is an industrialized module designed for the rigors of underground mobile mining machinery.

Designed to exacting requirements of IEC 60079.0 and IEC 60079.11 and MSHA CFR 30, this Ex I inclinometer module is designed and approved under certificate number IECEx TSA 23.0005X for worldwide explosive atmosphere regulatory approval allowing it to be installed into any underground environment after certification assessment.


The L12J I.S. Inclinometer is a high-performance inclinometer component featuring a three-axis inclinometer sensor with angle output based on capacitive 3D-MEMS technology. It is designed to be used on mining machines such as continuous miners, bolter miners, road headers, loaders, trucks, etc.

  • The L12J provides high stability, reliability, and quality and has extremely stable output over a wide range of temperatures and vibrations that guarantee reliable operation over the product’s lifetime.
  • Designed to interface with Pempek Systems L12E barrier to integrate with non-I.S. systems using RS422 communication interface, the Type L12J I.S. Inclinometer can be integrated into almost any control system with relative ease.
  • Highly ruggedized, industrial design using all brass and PTFE industrial-grade components.
  • Three-axis inclinometer sensor with angle output based on capacitive 3D-MEMS technology.
  • A nominal operating temperature range spanning -20°C to +40°C with an IP66/67 ingress protection rating.
  • Simplifies machine installation.
