Description

The Honeywell 2106B1201 is a Sensepoint 0-100% LEL flammable gas sensor featuring an M25 mounting thread size designed for industrial flammable gas monitoring. Built with poison-resistant catalytic bead sensor technology, this detector provides a 3-wire mV bridge circuit output signal for connection to Honeywell Analytics controllers or third-party DCS/PLC systems. Installation in potentially explosive atmospheres is accomplished using a suitable Ex d or Ex e approved junction box.

Features

  • Employs poison-resistant catalytic bead sensor technology.
  • Provides an industry-standard 3-wire mV bridge circuit signal output.
  • Features an M25 mounting thread connection.
  • Constructed with Polyphenylene Sulphide (PPS) body material.
  • Delivers IP65 ingress protection as standard, and IP67 when fitted with weather protection.
  • Factory-set operation designed for simple replacement.

Applications

  • Industrial gas monitoring in hazardous and explosive atmospheres.
  • Flammable gas detection for new and retrofit plant installations.
  • Integration with industrial control systems, DCS, and PLC equipment.
