SWA70-CA2A2A1 概述
A WirelessHART Adapter is an industrial wireless interface module that bridges legacy wired HART field instruments onto a WirelessHART mesh network. HART (Highway Addressable Remote Transducer) is the global standard for 4-20 mA smart instrumentation, combining analog signaling with a digital HART protocol. WirelessHART extends this standard to IEC 62591 (HART over IEEE 802.15.4 radio at 2.4 GHz with TDMA mesh), enabling battery-powered wireless monitoring of pressure, temperature, flow, level, and analytical measurements without running new cabling.
Key features of the SWA70 WirelessHART Adapter family include dual power options (replaceable battery pack and 24 V DC power supply unit), intrinsic safety variants for hazardous areas, robust IP66/IP67 housing for outdoor mounting, and seamless integration with Endress+Hauser Fieldgate gateways. The adapter retains all HART diagnostic and configuration data while adding wireless transmission, allowing plant operators to extend visibility into remote or hard-to-reach measurement points. Radio output is 10 dBm EIRP typical on the 2.4 GHz ISM band with mesh self-healing routing.
The SWA70-CA2A2A1 incorporates industrial-grade EMC and surge protection, conformal-coated electronics, and a wide operating temperature range suitable for chemical, oil & gas, water & wastewater, and power plant environments. Its internal mesh radio (IEEE 802.15.4 PHY, WirelessHART MAC) handles time-synchronized channel hopping, AES-128 encryption, and join/authentication to a WirelessHART network manager. Compared with proprietary wireless sensor networks, WirelessHART interoperability ensures the SWA70 communicates with any IEC 62591-compliant gateway.
Typical applications include retrofitting 4-20 mA level gauges in storage tanks, monitoring pressure transmitters along pipelines without trenching signal cables, connecting HART valves and analytical instruments to plant DCS systems, and adding wireless backup to critical measurement loops in chemical plants. Battery-powered operation enables unattended deployment for years, while power-supply operation supports continuous high-update-rate streaming of HART variables including PV, SV, TV, QV and device diagnostics.
Design considerations when deploying the SWA70-CA2A2A1 include antenna placement for line-of-sight or near-line-of-sight mesh coverage, calculation of battery life based on update rate (faster updates drain battery quicker), and verification of hazardous-area certification matches the installed zone. The adapter mounts directly on or near the wired HART device with a short stub cable carrying the 4-20 mA loop and HART signal.
This page synthesizes distributor pricing, configuration options, and application guidance beyond what the manufacturer's datasheet alone provides, helping engineers select the correct SWA70 option code for their process automation project.

典型应用
SWA70-CA2A2A1 适用于 6 应用s: Wireless Tank Level Monitoring, Pipeline Pressure Transmitter Retrofit, Chemical Plant HART Valve Diagnostics, Water & Wastewater Treatment Monitoring, Power Plant Steam and Emissions Monitoring, Tank Farm and Terminal Inventory Automation.
Wireless Tank Level Monitoring
The SWA70-CA2A2A1 attaches to a wired 4-20 mA/HART level transmitter on a storage tank and wirelessly relays level readings to a WirelessHART Fieldgate. With IEC 62591 mesh networking, the SWA70 operates unattended on battery power for years, enabling tank-farm monitoring without trenching signal cables. Its IP66/IP67 housing tolerates outdoor weather and wash-down environments, and AES-128 encryption ensures measurement data integrity across the mesh.
推荐
Pipeline Pressure Transmitter Retrofit
Pipeline operators retrofit existing 4-20 mA/HART pressure transmitters with the SWA70-CA2A2A1 to add wireless monitoring along long right-of-way runs where cable trenching is impractical. The SWA70's 2.4 GHz IEEE 802.15.4 radio hops measurements across neighboring adapters via self-healing mesh, providing redundant communication paths. Battery or 24 V DC powering suits remote wellhead and compressor-station deployments in oil & gas fields.
推荐
Chemical Plant HART Valve Diagnostics
The SWA70-CA2A2A1 brings wireless HART diagnostics from smart valve positioners and analytical instruments into the plant DCS, eliminating manual walk-around data collection. Intrinsic-safety variants allow installation in Zone 1 hazardous areas common in chemical reactors. Each SWA70 streams PV, SV, TV, QV variables plus device diagnostics over WirelessHART, integrating with asset management software for predictive maintenance.
推荐
Water & Wastewater Treatment Monitoring
Municipal water utilities deploy the SWA70-CA2A2A1 to add wireless connectivity to flow, pH, and turbidity meters in distributed well fields and lift stations. Battery-powered operation eliminates the need for utility power at remote sites, while mesh networking extends coverage across large treatment plant footprints. SWA70 IP66/IP67 protection handles outdoor and wet-environment installations typical of wastewater aeration basins.
推荐
Power Plant Steam and Emissions Monitoring
Power-generation operators use the SWA70-CA2A2A1 to retrofit steam flow, drum-level, and emissions analyzers onto wireless mesh networks, supporting condition-based maintenance and emissions compliance reporting. Wide operating temperature tolerance suits boiler-house environments. HART diagnostic data (device alert logs, calibration status) flows wirelessly to control rooms without dedicated signal cabling runs.
推荐
Tank Farm and Terminal Inventory Automation
Bulk-storage terminal operators attach the SWA70-CA2A2A1 to legacy 4-20 mA/HART level gauges to feed automated inventory management systems via WirelessHART. Each tank's level, temperature, and HART diagnostics stream through the mesh to the gateway, then into ERP systems for real-time volume reconciliation. Battery operation with multi-year life minimizes maintenance visits to remote tank farms.

设计说明
Confirm the SWA70-CA2A2A1 option-code string matches the target hazardous-area classification before ordering. Different position codes select non-IS, Ex i (intrinsically safe), or explosion-proof variants; selecting the wrong code can result in equipment that cannot be legally installed in Zone 1 areas. Cross-reference with the TI00026SEN datasheet approval matrix.
Place the SWA70 antenna with clear line-of-sight to neighboring WirelessHART nodes wherever possible. Metal obstructions (vessels, pipe racks, cable trays) attenuate the 2.4 GHz signal significantly. Mount the adapter vertically with the antenna pointing upward, and avoid mounting directly against large metal surfaces which create RF shadows. Plan mesh redundancy with at least two neighboring routers.
Battery life is dominated by the configured update rate. According to the Endress+Hauser datasheet, update rates of 1 second can reduce battery life to months, while 4-8 second rates typically yield multi-year operation. For continuous high-rate streaming, choose the external power supply option to avoid premature battery replacement. Calculate expected battery life using the E+H sizing tool before deployment.
