The CXT Wireless gas detection sensors are easily and economically deployable in both permanent and temporary installations. This low-power sensor assembly utilises infrared technology for combustible hydrocarbons. All component parts are rated for Class I, Division 1, Groups C and D hazardous areas.
This advanced field device consists of a Model CXT low-power infrared gas-detection sensor and a wireless transceiver, packaged in a single enclosure.
An internal battery pack powers the device using disposable “D” cell (3.6V) batteries, enabling continuous operation for up to 9 months. An optional lithium-ion rechargeable battery pack allows for five months of operation (not available with ATEX or IECEx approvals). Solar panels can charge battery packs in safe areas.
Reliable wireless technology
The proprietary “self-healing mesh” technology operates at 2.4 GHz and complies with worldwide use of unlicensed radio-frequency appliances. Wireless network integrity and security are accomplished using direct sequence spread spectrum DSSS programming topology.
Wireless applications can be as simple as a single field device communicating with a host display, or as complex as any number of field devices forming a network of subscribers. Each device in the network is assigned a unique device identifier, or UID. Every device in the network can act as a router and repeater for all other devices in the network. This means that subscribers can “hop” through neighbouring devices to communicate with each other, thereby widening network access points.
This technology creates a robust network that automatically routes around congestion and line-of-sight obstacles, improving throughput as subscriber device density increases.
