WirelessHART Adapter Communicates Process Variables

April 20, 2010
MACTek Corporation recently announced the release of its WirelessHART adapter, a universalcommunication device for use with both analog and HART-enabled devices. As the

newest member to the family of MACTek HART-enabled products, the Bullet provides a cost-effective means to access process measurements and communicate process variables and other valuable information to the control room without wires. The Bullet WirelessHART Adapter is now available for sale in a general purpose model for use in non-hazardous areas with deliveries starting in May. The IS and Ex-proof models will be available early in the 3rd quarter of 2010.

The Bullet can also be installed on a non-smart (analog only) device and will transmit a digital representation of the analog 4-20mA PV to the control room over the WirelessHART network which can save labor cost by eliminating manual recording of data.

The Bullet enables existing wired HART field devices from any supplier to communicate with host applications by means of WirelessHART technology. The Bullet is installed permanently by wiring it directly to a standard HART field device, or connecting it anywhere on the 4-20mA current loop with a junction box. A wired HART field device retrofitted with the Bullet communicates its analog process variable over the existing wiring to the existing DCS with no wiring changes. The Bullet simultaneously communicates the digital PV and device diagnostic information over the WirelessHART network.
