Pepperl+Fuchs extends its WirelessHART portfolio with the “BULLET\u201d. This loop-powered WirelessHART adapter enables new and existing wired 4 mA \u2026 20 mA and HART field devices to communicate measurement, diagnostic, and parameterization data wirelessly. It is the only WirelessHART adapter on the market with an explosion proof Ex d housing and is suitable for use in explosion hazardous areas up to Zone 1\/21, Class I, Div. 1 (also available as an intrinscally safe version for use in Zone 0 and a general purpose version).<\/p>\n

Rugged housing for challenging industrial environments<\/strong><\/p>\n

An extremely rugged aluminum housing contains all electronic components, including the antenna \u2013 the unit is built to withstand harsh environmental conditions in process plants. The BULLET is permanently installed by attaching it directly or via conduit fitting to an Ex d field device or by being mounted on a junction box. Additionally, the Ex i version of the BULLET is also suitable for use with intrinsically safe field devices.<\/p>\n

StepVolt technology optimizes available loop power<\/strong><\/p>\n

When using the BULLET, no additional battery is needed. Connection of HART devices is possible as well as connection of 4 mA \u2026 20 mA devices, enabling flexible adaptation to changing application requirements.<\/p>\n

The BULLET supplies itself with energy from the 4 mA \u2026 20 mA current loop, using a special technology called \u201cStepVolt\u201d. This technology allows users to set insertion voltage from 1 V to 2.5 V in order to optimize the usage of available loop power and wireless communication bandwidth.<\/p>\n

The BULLET provides reliable performance even under worst case low-current conditions, where there is very little power available \u2013 when using transmitters on very long cable runs or with intrinsically safe barriers. In scenarios where more power is available, the BULLET provides a higher amount of WirelessHART packets per second, leading to an increased performance of the overall WirelessHART network.<\/p>\n

Multidrop of up to eight devices with one WirelessHART adapter<\/strong><\/p>\n

The BULLET is equipped with a powerful multidrop feature that significantly lowers the cost of adding devices to an existing WirelessHART network. With a single BULLET, up to eight field devices can be multidropped. This is especially useful for monitoring tank farms and pipelines.<\/p>\n
