Bullet adapter can be added to analog transmitters to increase communication options, including diagnostic data transmission.The Bullet WirelessHART adapter is a straightforward solution to add a wireless interface to conventional analog and HART-enabled wired field instruments. Bullet manufacturer MACTek Corporation has now joined forces with Moore Industries to market and supply the device jointly Moore Industries’ worldwide sales network.

A Bullet can send process signals from a single device or up to eight multi-dropped HART transmitters on a WirelessHART link. Download a datasheet. In addition, it can work with Moore Industries’ TCS Temperature Concentrator System to send up to 16 temperature measurements across a WirelessHART network. Given its price, this offers a low-cost approach to connect HART devices to a wireless network. As an interface solutions provider, Moore Industries will work with customers on custom multi-drop applications to add new measurement points to the network at a cost below traditional wiring and individual wireless transmitters.

The full line of GP (general purpose), IS (intrinsically safe), and XP-rated Bullet products allow users to get the most out of all smart HART devices made any manufacturer.

“Moore Industries and MACTek worked together to provide a product that enhances the capabilities of our current line of smart HART products,” said Moore Industries founder and president Leonard W. Moore. “The Bullet WirelessHART Adapter solves the challenge of connecting new or existing smart HART or analog devices to a wireless network without incurring extensive additional costs. It’s a rugged solution suitable for all industrial locations that boasts a package of features unavailable in other products.”

Supporting both mesh and star network configurations, the Bullet can be connected directly to a HART device or at any junction box along the HART 4-20 mA loop. It sends process signals including first, second, third, and fourth measurement variables, custom diagnostic and alarm data, and custom commands. It also accepts analog signals such as 4-20 mA, so it can interface legacy analog instruments to WirelessHART networks.

The rugged XP-rated model can be powered either by an external dc power supply or by scavenging from existing loop-power. When using loop-power, it utilizes the patented StepVolt technology to manage the balance between power demands and wireless communication bandwidth. By setting insertion voltage in steps from 1 to 2.5 volts, StepVolt allows the transmitter to draw the power it needs without unnecessarily sacrificing available bandwidth.

“This joint marketing relationship brings together two recognized leaders in the field of HART-enabled products – MACTek with our full line of HART modems and Moore Industries with its HART loop interfaces and other HART products,” said Thomas Holmes, president of MACTek Corporation. “The Bullet WirelessHART Adapter allows Moore Industries to provide an exciting addition to their existing smart HART solutions along with a standalone product that can be used with any registered third-party smart HART device.”
