Detcon CXT DM-H2S – Hydrogen Sulfide Gas Detection Sensor

Detcon CXT DM-H2S - Hydrogen Sulfide Gas Detection Sensor

Detcon Model CXT-DM-H2S SmartWireless® hydrogen sulfide gas detection sensors are easily and economically deployable in both permanent and temporary installations. These low power sensors assemblies utilize electrochemical technology for a long list of toxic gases. All component parts are rated for Class 1; Division 1, Group C, D hazardous areas. These advanced field devices consist of a Detcon Model Series CXT low power gas detection sensor, and wireless transceiver packaged in a single enclosure. Power is provided by an internal battery pack with disposable “C” cell (3.6V) batteries capable of continuous operation for greater than 60 days. An optional lithium ion rechargeable battery pack allows for 5 months operation. Solar power options allow for indefinite operation. An optional battery pack with
disposable “D” cell (3.6V) batteries is capable of delivering up to 9 months operation.

Detcon’s proprietary “Self Healing Mesh” technology operates at 2.4 GHZ and conforms to non licensed radio frequency appliance usage around the world. Wireless network integrity and security is 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 any number of field devices forming a network of subscribers. Each device in the network is assigned its unique device identification or a 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 neighboring devices to communicate with each other thereby widening network access points. This unique and innovative technology is designed to create
a robust network that automatically routes around congestion and line-of-sight obstacles while improving throughput as subscriber device density increases.

Standard network configuration is of the master/slave mesh type (320 Transceiver). An optional and proprietary technology referred to as “Fault Tolerant Safety Network” (300Transceiver) is also available which guarantees that no single point of failure will interrupt communications between devices on the rest of the network, including loss of HMI. Processing power is, in a sense, shared among all devices. There is no controller dependence. Each device in the network is capable of acting as the network master, processing real time data and issuing commands to other devices in the network.
