Storage & Installation Guidelines
Storage Requirements
- Store in dry, temperature-controlled warehouse (10°C ~ 30°C), low humidity <70% RH
- Keep sealed in original factory packaging; avoid vibration, dust, corrosive vapors, direct sunlight
- Do not store alongside solvents or reactive chemicals that can poison catalytic bead elements
Installation Instructions
- Isolate power supply to the gas transmitter before sensor replacement
- Carefully remove old sensor probe, avoid damage to wiring terminals
- Thread 2106B2310 M20 sensor into transmitter housing, torque to manufacturer recommended value (do not over-tighten)
- Complete wiring connections following Honeywell Sensepoint HT wiring diagram
- Perform gas calibration and functional test after installation
- Only certified technicians should install and calibrate in ATEX hazardous zones
FAQ
Q: What transmitter does 2106B2310 fit? A: It is designed exclusively for Honeywell Sensepoint HT high temperature flammable gas detector units.
Q: Can this sensor work for hydrogen detection? A: Yes, catalytic bead sensor responds to hydrogen and most combustible hydrocarbon gases, calibration required for target gas.
Q: What is the typical service life? A: Expected lifespan is 3–5 years under normal clean industrial conditions; catalytic bead can be poisoned by silicones, lead or sulphur compounds, shortening service life.
Q: Is this an ATEX certified sensor? A: Yes, 2106B2310 carries ATEX certification for use in explosive hazardous areas.
Q: Does it ship factory pre-calibrated? A: Factory baseline calibration is completed, but site gas calibration is mandatory after field installation.
