Honeywell SPXCDXSHXSS Gas Detector

Honeywell SPXCDXSHXSS Gas Detector (Sensepoint XCD H₂S Sensor Cartridge)

 

 

The Honeywell SPXCDXSHXSS is a replacement gas sensor cartridge (H₂S hydrogen sulfide sensor) used in the Honeywell Sensepoint XCD fixed gas detection system.

It is a critical safety detection component, designed to measure toxic hydrogen sulfide gas (H₂S) in industrial environments.

What it actually is

This is not a controller or transmitter by itself.

It is a sensor head / cartridge, meaning:

• It detects gas concentration in the air
• It sends signal to the XCD transmitter system
• It is part of a fixed gas safety monitoring system

It does NOT:

• Control machinery ❌
• Act as PLC or relay ❌
• Perform logic functions ❌

System Role (Simple)

Air in industrial area
→ SPXCDXSHXSS sensor (this unit)
→ XCD transmitter/display unit
→ PLC / alarm system
→ safety actions (alarm / shutdown / ventilation)

So it acts like a “toxic gas detection sensor head.”

Key Features

• Detects toxic H₂S gas (highly hazardous gas)
• Plug-in replacement sensor cartridge design
• High accuracy electrochemical sensing
• IP66 protection for harsh environments
• Designed for hazardous area certification systems (ATEX/IECEx depending model)
• Works with Sensepoint XCD fixed gas detector system

Typical Applications

• Oil & gas plants
• Refineries
• Chemical processing facilities
• Wastewater treatment plants
• Confined space monitoring systems
• Industrial safety gas detection networks

Advantages

• Fast detection of toxic gas leaks
• Replaceable sensor cartridge (easy maintenance)
• Designed for harsh industrial environments
• High reliability safety monitoring
• Integrates into fixed plant safety systems

Important Notes

• Not a PLC ❌
• Not a relay ❌
• Not a control module ❌
• Not a standalone transmitter ❌
• It is a gas sensor cartridge for Honeywell XCD detector system ✔

Precautions

• Must be calibrated after installation
• Must match correct XCD system version
• Do not install without compatible transmitter
• Handle carefully (sensor element is sensitive)
• Requires periodic replacement (consumable part)
