Mactek has announced the release of two wireless adapter solutions that it claims provide options and alternatives for users to access information from their intelligent Hart-enabled field devices.

The company’s one-port wireless adapter and the two-port wireless adapter are for use in WirelessHart networks and will allow wireless access to Hart data in existing Hart-enabled field devices.

The one-port wireless adapter – 1-Port WA – enables existing wired Hart field devices to communicate with host applications by means of WirelessHart technology.

The 1-Port WA is installed permanently by screwing it into an available spare port of Hart field device.

Other installation options are possible anywhere on the loop using a junction box or ‘T’-fitting.

A wired Hart field device retrofitted with a 1-Port WA communicates its PV over the existing wire pair to the DCS and simultaneously communicates diagnostic and alarm data over the WirelessHart network to process management, asset management and engineering applications.

The 1-Port WA has options for power scavenging (loop powered) or local power.

Power from the loop saves the long-term cost of battery maintenance, replacement and disposal programmes.

Local power can be used when available; for example, when the field device is also direct powered.

The 1-Port WA will be ATEX/IS and XP-certified for use in hazardous areas.

The two-port wireless adapter (2-Port WA) enables existing wired Hart field devices to communicate with host applications by means of WirelessHart technology.

The 2-Port WA is installed permanently at any convenient location along the loop.

Mactek Passthrough technology makes installation easy and quick by passing two wires from the DCS and two wires from the Hart field device into the cavity of the 2-Port WA and connecting the four wires to terminal blocks.

A wired Hart field device retrofitted with a 2-Port WA communicates its PV over the existing wire to the DCS and simultaneously communicates device diagnostic and alarm data over the WirelessHart network to process management, asset management and engineering applications.

The 2-Port WA has options for power scavenging (loop powered) or local power.

Power drawn from the two-wire loop saves the long-term cost of battery maintenance, replacement and disposal programmes.

Local power can be used when available; for example, when the field device is also direct powered.

The 2-Port WA will be ATEX/IS and XP-certified for use in hazardous areas.
