New Control For Gas Detection: Oldham introduces WX Series of gas detection alarm controllers
Industrial Scientific company Oldham, a supplier of fixed gas detection equipment and services, has introduced the WX Series of gas detection alarm controllers. The new line includes the WX4 four-channel, WX16 16-channel and WX64 64-channel controllers, targeting the oil and gas, offshore drilling, and utility and power industries. The WX4 is designed for continuous monitoring of up to four analog or digital gas measurements. Its optional wireless technology can receive and transmit gas readings, providing wiring cost savings and application flexibility, said Oldham. The WX4 accepts four 4 to 20 mA, bridge or wireless inputs and provides 4 to 20 mA, Modbus RTU or wireless outputs. An option for solar power is also available. Information can be
viewed via the main screen view, bar graph screen or trend screen.
Four types of wall-mounted enclosures are offered: nonmetallic, painted steel, stainless-steel wall mount and explosion-proof aluminum. The WX16, designed for the continuous monitoring of up to 16 analog or digital gas measurements, comes standard with two RS-485 ports and can be configured to receive and transmit wirelessly. The WX16 can be configured to accept up to 16, 4 to 20 mA, bridge sensor, Modbus RTU and wireless ModBus RTU inputs. The WX16 has four standard 5 Amp SPDT relay configured for two common alarms, one common fault and one common horn. Additional discrete relays may be added in groups of eight.
Other features include programmable relays, a backlit LCD screen and 24-hour data logging. LCD displays include bar graph, trend chart and a combination screen. Enclosure options are panel/rack mount, nonmetallic mount, stainless-steel wall mount and explosion-proof wall mount. The WX64 is designed for the continuous monitoring of up to 64 analog or digital gas measurements. It features a color display, data logging via 2GB SD Card to store up to one year of data, zoning, dual RS-485 ports and programmable relays. The WX64 also has an embedded Web page that enables remote viewing and configuration of all 64 channels via a standard Web browser.
The WX64 accepts 4 to 20 mA, bridge sensor, Modbus RTU, Modbus TCP and wireless channels. Multiple display screens present information, including the main data screen, bar graph, 24-hour trend, combo and zone screens. Available enclosures include panel/rack mount, nonmetallic wall mount and explosion-proof aluminum wall mount. In addition to the individual features, the WX Series controllers are designed to communicate with each other via their analog, digital or wireless signals. Oldham said this provides the flexibility to enable local area controllers to report their readings back to a primary alarm controller. Indoor operating range is 900 m and outdoor range is up to 16 km. Operating temperature range is -25° to 60°C.
