AE200Field Analysis Transmitter

Harsh chemical plants expose transmitters to corrosive atmospheres, moisture, electrical noise, and potential explosion hazards. The AE200 field transmitter features a two-wire intrinsically safe design with isolated transmission outputs to prevent ground loop interference in petrochemical environments. For multi-parameter field sites, the AU400 provides IP66 protection, an AC/DC power supply, and UL94V-0 flame retardancy. Transmitters must be paired with appropriate chemical-resistant pH, conductivity, or DO sensors. Since mounting arrangements and safety certifications vary by site region, specific explosion-proof compliance must be confirmed for the selected configuration. Please inform our engineering team of your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output.

Selecting the communication protocol depends on control system architecture and data requirements. Standard isolated 4-20mA current loops provide reliable noise-immune transmission for primary process parameters over long cable distances. Digital RS485 Modbus RTU interfaces, available on transmitters like the AU400 and B Series DIN Rail units, allow digital PLCs to read primary values, secondary temperature data, diagnostic status, and execute remote calibrations. Wireless options like NB-IoT are also available on selected models. Electrical isolation and power loop requirements vary, so exact field wiring compatibility must be confirmed for the selected configuration. Share your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output with our application engineers.

The AE200 field transmitter is specifically designed for safe operation in hazardous industrial environments such as refineries and chemical processing units. Operating on 24VDC (+/-10%) power with low 2W consumption, its two-wire intrinsically safe circuit prevents spark ignition in flammable atmospheres. The unit processes pH or ORP inputs with high loop accuracy (+/-0.02 pH) and features isolated dual 4-20mA current outputs with HART 7 protocol support. Display options include a 2.8-inch monochrome LCD with bilingual Chinese/English menus inside an IP65 housing. Exact explosion-proof hazardous area classification ratings must be confirmed for the selected configuration.
