PT1 – Pressure Transmitter

The PT1 – Pressure Transmitter accepts an input from one pressure sensor, load cell, or transducer. The PT1 has a built-in calibration curve that linearizes the connected sensors for better accuracy and outputs the corrected answer though current loops or Modbus (RS-485). The calibration changes per application and is set by Custom Sensors and Technology, however, the calibration curve can be changed by the user through Modbus. For pressure applications, the default ranges are 0-10psi, 0-30psi, 0-60psi, while the full range is -10-100psi.  The default values can be changed through Modbus, or defined when ordering the PT1 and will be set by Custom Sensors and Technology. A standard M12 connector integrates directly to the PT1 Pressure Transmitter that includes 4-20 mA, Modbus RTU, and optional remote display.
