Description

The OTIS OI-6750-NXP is the non-explosion-proof 2-wire loop-powered gas detector — the simplest way to add a gas detection point to an existing 4–20 mA loop in a general-purpose area. Two wires carry both power and the gas reading back to the controller, PLC, or DCS — no separate power wiring.

Choose from 24 gas and range combinations, including specialty gases like arsine, phosphine, ethylene oxide, and methyl mercaptan. The loop-powered design makes it a natural fit for retrofits — it drops onto existing 2-wire infrastructure in warehouses, mechanical rooms, and other non-classified spaces.

  • 2-wire loop-powered — power and signal over a single twisted pair
  • 4–20 mA output integrates with PLCs, DCS, and gas controllers
  • 24 gas/range combinations incl. ASH3, PH3, ETO, CH3SH
  • Ideal for retrofits — reuses existing 2-wire loop wiring
  • Magnetic non-intrusive calibration interface
