SX-PTCB Series

The SX-PTCB Series direct-mount process pressure transmitter provides high-accuracy measurement of gauge and absolute pressure in liquids, gases, and steam, and can also be used for tank and vessel level, density, and interface measurement. Depending on the selected configuration, it provides a 4–20 mA/HART, RS-485 Modbus RTU, or Profibus PA output. With excellent long-term stability, multiple display and process-connection options, IP67 ingress protection, and optional ATEX intrinsically safe or flameproof approvals, it is suitable for oil and gas, petrochemical and chemical processing, power generation, water and wastewater, food and beverage, pharmaceutical, pulp and paper, metal smelting, and marine and offshore applications.
