I need to know what are the HART 7 Input and Output devices available in the market today that can be purchased. If anyone is aware, please provide some vendors which support HART 7 devices.
Honeywell, Emerson, ABB, Siemens, Endress+Hauser, and many more make Hart 7 devices. All IEC62591-WirelessHART devices are Hart 7 and there are about 20 vendors supplying those.
Hart 7 is for both wired and wireless HART transmitters.
I Googled the site and got these:
MACTek Corporation Bullet
Fluid Components International ST100
ABB Automation Products GmbH NHU200-WL
PR Electronics A/S PR6337
Azbil Corporation GASCVD
Analog Devices Inc. DEMO-AD5700D2Z
Analog Devices, Inc. DEMO-AD5700D1Z
Yokogawa Electric Corporation YTA70-J
Yokogawa Electric Corporation EJA-NEXT
Rosemount Inc. 2160
Yokogawa Electric Corporation DYF
ESP Safety, Inc. SGOES
Rosemount Analytical Inc. Model 56
HACH - LANGE Inductive Conductivity Sensor Module, sc200
HACH - LANGE Sensor Module, pH/ORP/DO, sc200
Endress+Hauser SWA70 / WirelessHARTR Adapter
Endress + Hauser Liquiline CM44x
Note that HART7 devices are only compatible with HART7 systems. So if you have a HART5 system, make sure to use devices that also support HART5.
Emerson's HART7 devices are configurable to use either HART5 or HART7 so they work on any system
Like Walt said, the big deal with HART7 is WirelessHART. No significant change for 4-20 mA devices. HART5 still does the job
