B SeriesDIN Rail Analysis Transmitter

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.

Designed for OEM bioreactor control cabinets, the B Series DIN Rail transmitter optimizes panel space while meeting strict bioprocess batch logging requirements. It incorporates 3-terminal isolation to eliminate signal noise and ground loop interference. Specifically tailored for fermentation systems, its 3-in-1 software design enables electrodes without integrated temperature sensors (such as S8 or AK9 connector pH probes) to utilize a separate vessel PT100 probe for automatic temperature compensation of pH and DO measurements. Operating on 24VDC (<2W), it outputs 4-20mA (NAMUR NE43 compliant) and RS485 Modbus RTU for remote PLC calibration. PLC programming libraries must be confirmed for the selected configuration. Provide your medium, flow range, pressure, temperature, viscosity, tube size, process connection, and required output.

Medical and laboratory equipment OEMs require compact, reliable instrumentation with standardized digital communications. For gas delivery in analyzers or bioreactor sparging, the FS-600 MEMS thermal gas flow meter provides 1:100 turndown and fast response (50-1000 ms) in a compact block with a rotatable screen. Liquid reagent dosing uses the FS-910 inline ultrasonic meter for micro-flows down to 120 ml/min. Analytical sensor integration is simplified by the B Series DIN Rail transmitter, which offers 24VDC power, isolated Modbus RTU, and compact mounting inside analyzer cabinets. Custom OEM mounting interfaces must be confirmed for the selected configuration.
