Pepperl+Fuchs extends its WirelessHART portfolio with the "BULLET”. This loop-powered WirelessHART adapter enables new and existing wired 4 mA … 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 (also available as an intrinscally safe version for use in Zone 0 and a general purpose version).
Rugged housing for challenging industrial environments:
An extremely rugged aluminum housing contains all electronic components, including the antenna – 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.
StepVolt technology optimizes available loop power:
When using the BULLET, no additional battery is needed. Connection of HART devices is possible as well as connection of 4 mA … 20 mA devices, enabling flexible adaptation to changing application requirements.
The BULLET supplies itself with energy from the 4 mA … 20 mA current loop, using a special technology called “StepVolt”. 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.
The BULLET provides reliable performance even under worst case low-current conditions, where there is very little power available – 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.
Multidrop of up to eight devices with one WirelessHART adapter:
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.
Highlights at a glance:
- Only Ex d certified loop-powered WirelessHART adapter on the market, suitable for use in explosion-hazardous areas up to Zone 1
- Rugged Ex d aluminum housing with fully encased antenna for harsh environments
- Handles both 4 mA … 20 mA and HART field devices, giving flexibility in applications
- StepVolt technology makes very low voltage drop possible
- Multidrop of up to eight field devices with a single BULLET saves network extension costs
