WirelessHART adapter from MacTek
MacTek Corp., provider of HART PC Modems, completed development of its wireless adapter for use with HART-enabled devices. MacTek Bullet provides a cost-effective means of access to real-time information from installed intelligent HART-enabled field devices. The Bullet is the latest addition to the MacTek Viator line of PC modems. The adapter will be available in a general purpose non-certified model for use in non-hazardous areas in October 2009, company says.
Certified IS and Ex-proof model will be available after obtaining international agency approvals with shipment expected to start early first quarter 2010.
The Bullet enables existing wired HART field devices to communicate with host applications by means of HART Communications Foundation wiring to the existing DCS and simultaneously communicates diagnostic and device information over the WirelessHART network to process and asset management applications.
The Bullet has options for power scavenging or local/direct power . When powered by the current loop, it saves users the long term cost of battery maintenance, replacement and disposal programs. Local/direct power option can be used when the field device is powered either by a power supply or an external battery/solar system. In the case of external battery power, the Bullet provides battery power management by cycling the field device power and taking periodic readings.
Thomas Holmes, MacTek president, says because the device connects to existing installed HART-enabled devices, it “provides a huge benefit to users as they continue to lower their operating cost by providing access to the stranded valuable information sitting in their measurement and control assets.”
MACTek’s is submitting the device to required international agencies and the HART Communication Foundation for testing, certification and registration. Compliant with the HART communication specifications, the product family of wired and wireless solutions is easy to use– no configuration required – reliable and work with any HART-enabled device.
