Aplisens APC-2000ALW Series Smart Pressure Transmitter is designed for precise measurement of pressure, underpressure, and absolute pressure of gases, vapors, and liquids. The transmitter features a piezoresistant silicon sensor that is isolated from the medium by a diaphragm and a specially selected manometric liquid. The casing is made of either aluminium alloy cast or 316SS stainless steel, providing robust protection with IP66/IP67 ratings. Aplisens APC-2000ALW Series Smart Pressure Transmitter is an advanced and versatile tool for accurate pressure measurement and control in various industrial applications, offering robust construction, flexible installation options, and comprehensive configuration capabilities.


  • Pressure Measurement: Suitable for measuring pressure, underpressure, and absolute pressure of gases, vapors, and liquids.
  • Versatile Installation: Ideal for various industrial applications requiring precise pressure measurement and control.

Technical Characteristics

  • Active Sensing Element: Piezoresistant silicon sensor separated from the medium by a diaphragm and manometric liquid.
  • Casing Material: Available in aluminium alloy cast or 316SS stainless steel.
  • Protection Degree: IP66/IP67, ensuring durability and resistance to harsh environmental conditions.
  • Display and Casing Rotation: Allows the use of a local display, rotation of the display, rotation of the casing by 0–340° relative to the sensor, and a choice of cable direction.

Data Interchange and Configuration

  • Identify the Transmitter: Easily identify the transmitter for maintenance and configuration purposes.
  • Configure Output Parameters:
    • Measurement units and the values of the start and end points of the measurement range.
    • Damping time constant.
    • Conversion characteristic (inversion, user’s non-linear characteristic).
  • Read Current Values: Access the currently measured pressure value, output current, and the percentage output control level.
  • Force Output Current: Set a specific output current value for testing and calibration.
  • Calibration: Calibrate the transmitter in relation to a model pressure for accurate measurement.
