The Honeywell Sensepoint XCD Gas Detector & Transmitter range provides comprehensive monitoring of flammable, toxic and oxygen gas hazards in potentially explosive atmospheres, both indoors and outdoors.

The standard XCD is an Ex-d gas detector suitable for use in Zone 1 environments and is available in 3 versions: flammable, oxygen and toxic. Each is supplied with a pre-installed stainless steel sensor cartridge and fully tested and calibrated ready for installation. Replacement sensor cartridges are available. Configuration and control of the unit is achieved through the use of a magnet removing the need to open the unit, while the tri-colour backlit display provides instant indication of the detector status at a glance.

The XCD catalytic sensor can be used to detect flammable gases in the range of 0 to 100% LEL while the infrared (IR) sensor versions are available for the detection of methane in the range of 0 to 100% LEL, propane (with cross sensitivities to ethylene and butane) and Carbon Dioxide (CO2). Both sensors are used in conjunction with the flammable version of the transmitter.

The electrochemical cell (EC) sensors are available for the detection of oxygen and toxic gases: Carbon Monoxide (CO), Hydrogen Sulphide (H2S), Nitrogen Dioxide (NO2) and Hydrogen (H2). Each detector is supplied with a pre-fitted sensor, nylon weather protection, a stainless-steel blanking plug, a magnetic wand, and hex keys. All transmitters are also available with Modbus interface as an option.

Users can modify detector operation using the LCD and magnet switches without ever needing to open the unit. This enables one-man, non-intrusive operation and reduces routine maintenance time and costs.

A tri-colour backlit LCD indicates the unit’s status at a glance, even from a distance. A steady green backlight indicates normal operation, flashing yellow indicates fault and flashing red indicates an alarm.

All detectors are supplied pre-configured and include 2 programmable alarm relays, 1 programmable fault relay as well as an industry-standard 4-20mA output (sink or source selectable) and Modbus.

The scale, range, relay operation, alarm set point and electronic tag number of the detector can be adjusted using the transmitter’s LCD and non-intrusive magnetic switches. Outputs are automatically inhibited during adjustment, thereby reducing the risk of false alarms at the control panel during maintenance.

Sensepoint XCD has an integral mounting plate for surface mounting or can be mounted to a horizontal or vertical pipe using the optional pipe mounting bracket. Electrical installation can be made using either a conduit or cable with suitable mechanical protection. Two M20 or ¾”NPT entries are provided (depending on certification). A weatherproof cap is also included for use in the harshest outdoor conditions. Other optional accessories include a sunshade/deluge protection, duct mounting kit and collecting cone.

Sensepoint XCD ensures easy installation and the fastest routine operation by removing the need for hot work permits in hazardous areas. Using easy-to-replace plug-in sensors, downtime is also reduced and ongoing costs are minimised through the use of poison-resistant flammable sensors, poison-immune infrared Hydrocarbon sensors patented Surecell toxic sensors and Reflex sensor health checks.
