PTL – Pressure Transmitter
The PTL – Pressure Transmitter accepts an input from one to four Wheatstone bridge sensors, typically pressure sensors or load cells. The PTL 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 PTL Pressure Transmitter that includes 4-20 mA, Modbus RTU, TMP outputs, and integrated color touch-screen display for benchtop lab settings.
The PT series is designed with auto-sensor detection to automatically interface with a wide variety of industry-leading pressure sensors available on the market including the CST Process Pressure Sensors. CST recognized the need to create a plug-and-play system to work with other sensor brands and created the PT series that automatically detects which type of sensor is plugged in and calibrates itself accordingly. Sensor interfacing is supported through standardized M12 connections and configurable transmitter parameters, allowing users to adapt the PT series to different sensor ranges, outputs, and calibration requirements.
