Banner has battery-powered wireless transceiver

Banner Engineering announced a new way to collect analogue, digital and temperature information in hazardous areas at the 2008 ISA show.

Banner's method moves the intrinsically safe power supply from the control room to a wireless transceiver.

The DX99 battery-powered node is a combination of three key technologies combined in a single housing: battery-based power supply; robust wireless technology for mission critical data; and intrinsically safe operation.

The DX99 uses a liquid lithium battery to produce an intrinsically safe power source for the transceiver and an external third-party sensor.

When combined with low-power consumption sampling electronics, the standalone unit can operate for up to 10 years on a single battery.

The DX99 wireless technology is a highly tuned subsystem designed with industrial process applications in mind.

It was designed to be reliable, secure and provide diagnostic information about the status of the wireless link.

It can transmit and receive up to three miles (150mw with 2dBi antenna) while consuming very little power.

Every DX99 has a built-in site survey mode that allows the installer to determine the quality of the wireless link.

The DX99 can provide intrinsically safe power to the sensor directly within the hazardous area.

The node can be added to an existing system with no need to run new conduit or pull new wires.

It can be installed in a matter of a few hours; simply 'peel and stick' where you need it.

As the DX99 is battery powered, it works best in applications that have low sensor power requirements, including thermocouple, digital, and RTD, loop powered sensors.

The DX99 uses a sampling technology to reduce power consumption and can be configured to sample each second.

If sampling every 16 seconds, the battery will last 16 times as long.

The DX99 can also be configured to report on change of sensor state, or in an alarm-only condition.

This further conserves power and extends battery life.

Proper sampling will provide 10-year battery life.

The DX99 will work in mobile situations and can eliminate umbilical cords running back to the control panel.

The DX99 was designed to run not only the radio system but also power a certified Class I sensor.

It is available in rugged polycarbonate housing or metal housing; both options are intrinsically safe and rated IP67.

Rugged polycarbonate housing models are certified for use in Class I, Division 1, Groups A, B, C, D; Class I, Zone 0, Group IIC; and Group IIC, Zone 0.

Metal housing models are certified for use in Class I, Division 1, Groups A, B, C, D; Class II, Division 1, Groups E, F, G; Class III, Division 1; Class I, Zone 0, Group IIC; Group IIC, Zone 0; and Dust, Zone 20.

Rugged polycarbonate housing works with external battery power to support all RF communications and provides supply power for third party 4-20mA and Namur process sensors.

Metal housing includes internal battery power for all RF communications and also provides supply power for third party 4-20mA and Namur process sensors.

Rugged polycarbonate housing offers internal or external antenna options and the metal housing offers external antenna only to support a range of mounting requirements.

Both housings allow simple DIP switch configuration.
