Honeywell Sensepoint XCD

Flammable, toxic and Oxygen gas detector for industrial applications

The Sensepoint XCD range provides comprehensive monitoring of flammable,

toxic and Oxygen gas hazards in potentially explosive atmospheres, both

indoors and outdoors. 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 clearly 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 alarm 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 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 on-going costs are minimised

through the use of poison resistant flammable sensors and patented

Surecell™ toxic sensors.

Sensepoint XCD Overview

There are three different types of the XCD transmitter for use with three different

families of sensors.

The mV type transmitter is for use with the mV family of XCD sensors including

catalytic sensors to detect flammable gases in the range 0-100%LEL and infrared

(IR) sensors for detection of Hydrocarbon gases in the range 0-100%LEL.

Two IR Hydrocarbon sensors are available; one linearised to Methane and one

linearised to Propane. The Propane version has linear cross sensitivities factors for

Ethylene, Butane and Pentane. There is also an IR CO2 sensor available in the range

0-2%Vol.

The EC type transmitter is for use with the EC family of XCD sensors including

Carbon Monoxide (CO), Hydrogen Sulphide, (H2S), Nitrogen Dioxide (NO2)

and Hydrogen (H2).

The Oxygen transmitter is for use with the Oxygen (O2) XCD sensors.

A transmitter can auto-recognise any sensor from within its sensor family.

The sensor simply plugs into the bottom of the transmitter and the transmitter

automatically configures itself accordingly.
