Overview

The EX2000RS Toroidal Conductivity Transmitter from Sensorex is an industrial‑grade conductivity transmitter designed for use with toroidal (inductive) conductivity sensors such as the TCS3020 series. It provides reliable measurement and monitoring of conductivity, total dissolved solids (TDS), salinity, and percent concentration. The instrument features a 4‑20 mA analog output and an RS‑485 serial interface supporting Modbus RTU or ASCII communication, enabling easy integration with automation systems. It is suitable for harsh environments and applications where minimal sensor maintenance and corrosion resistance are important, including wastewater, cooling towers, brine measurement, and chemical processing. The transmitter supports wall or panel mounting and offers versatile display and calibration features.
