Burkert 418982N 8225-AA-C1 Conductivity Transmitter

The Burkert 418982N 8225-AA-C1 Conductivity Transmitter is a panel- or wall-mounted solution that combines a replaceable conductivity sensor with a compact transducer and an integrated display in a durable polycarbonate housing, delivering a standard 4-20 mA conductivity signal for process control. It is designed to pair with Burkert’s 8220 remote conductivity sensor, with sensor cell constants and electrode materials varying by version: 0.01 and 0.1 cm⁻¹ variants use stainless steel electrodes, while 1.0 and 10 cm⁻¹ variants use graphite electrodes, and a Pt1000 temperature sensor is embedded for automatic temperature compensation, with compensation managed through Burkert’s multiCELL transmitter/controller 8619. The transmitter supports two wiring schemes depending on version—two-wire operation with the 4-20 mA signal carried on the power wires, or a three-wire arrangement with a separate output lead—and can be powered from an external supply of 12-30 VDC or 115/230 VAC. Conductivity measurement ranges from 0.05 µS/cm to 200 mS/cm, with typical accuracy around 3% of reading and a maximum of 5%, and temperature-related performance is tied to the chosen mounting hardware and fittings (e.g., S020 options) that determine fluid and temperature ranges, including PVC up to 0–50 °C, PP up to 0–80 °C, PVDF variants up to 0–100 °C, and immersion configurations up to 0–80 °C, making this transmitter suitable for water-treatment, pharmaceutical, and food-and-beverage applications requiring reliable conductivity monitoring and robust signal transmission.
