SPXCDALMHX – Honeywell Sensepoint XCD Gas Detector
The Honeywell SPXCDALMHX transmitter is an explosion-proof, fixed gas detector designed for continuous monitoring of Hydrogen Sulfide (H2S) in hazardous industrial areas. Engineered with Honeywell’s patented Surecell electrochemical sensor technology, this ATEX and IECEx certified transmitter delivers real-time H2S concentration readings (0-50 ppm) through an intuitive tri-color backlit LCD. Widely deployed across offshore oil rigs, petrochemical refineries, wastewater treatment plants, and gas processing facilities throughout Dubai, Riyadh, Singapore, and Jakarta, it features a rugged LM25 aluminum alloy housing for reliable operation in extreme environments.
Key Features & Product Highlights
-
Tri-Color Backlit Display: Intuitive LCD clearly shows operational status from a distance (Green = Normal, Yellow = Fault, Red = Alarm).
-
Non-Intrusive Calibration: One-man calibration and configuration via magnetic switches without opening the enclosure, ensuring hot-work permits are unnecessary.
-
Surecell Electrochemical Sensor: Delivers fast, accurate H2S detection with exceptional poison resistance and long operational life.
-
Integrated Relays & Outputs: Features industry-standard 4-20mA analog output along with two programmable alarm relays and one fault relay.
-
Explosion-Proof Housing: Robust LM25 painted aluminum enclosure rated for IP66, designed for harsh onshore and offshore environments.
-
Global Certifications: ATEX, IECEx, and Asian approvals ensure compliance with stringent international hazardous area standards.
