Siemens Sitrans AW210 WirelessHART adapter has received an explosion-proof rating for intrinsically safe (Ex ia), nonincendive (Ex nA) and explosion-proof (Ex d).

siemens0618With more than 35 million devices installed worldwide, HART technology is the most widely used field communication protocol for intelligent process instrumentation. The Sitrans AW210 adapter allows up to eight standard wired HART devices or one 4-20 mA to be connected to a WirelessHART network.  The integrated power management enables efficient usage of external batteries or energy harvesting components like solar panels, according to Siemens.

By installing the SITRANS AW210 on an existing analog-wired HART device, users can utilize all diagnostic information at the maintenance station without the risk of impaired operation.  In this case, the adapter is powered by the loop. WirelessHART devices, such as the Sitrans AW210, can offer plant operators increased plant transparency, productivity and performance, with common applications including processing monitoring and control, asset management, health, safety and environmental monitoring and temporary measurement
