The APRE-2000G is a smart differential pressure transmitter designed for low-range measurements, capable of measuring pressure, underpressure, and differential pressure in gases. It features programmable range, zero shift, damping ratio, and characteristic, supporting the HART communication protocol. With an accuracy of up to 0.1%, it is suitable for applications such as measuring blast pressure, chimney draughts, and pressure/underpressure in furnace chambers. The transmitter is available in different versions (PZ, PD, N) with varying features like IP ratings, materials, and mounting options. It can withstand overpressure up to 1 bar and has a housing with protection ratings of IP65, IP66, or IP67. The device can be configured for various units of pressure, start and end points of the measuring range, damping time constant, and conversion characteristics. It supports calibration with a standard pressure reference and can be communicated with using a KAP-03 communicator, other HART communicators, or a PC with an HART/USB converter and RAPORT 2 configuration software.

Use Cases

  • Measurement of blast pressure
  • Measurement of chimney draughts
  • Measurement of pressure / underpressure in furnace chambers
  • Gas-flow measurement systems using reducing pipes or other impeding elements

Capabilities

  • Programmable range, zero shift, damping ratio and characteristic
  • 4...20 mA output signal + HART protocol
  • Accuracy from 0.1%
  • ATEX Intrinsic safety (only APRE-2000G/PD, APRE-2000G/PZ)
  • Calibration with reference to a standard pressure
  • Communication with KAP-03 communicator, other Hart communicators, or a PC with HART/USB converter and RAPORT 2 configuration software
  • Data interchange to identify the transmitter, read the currently measured pressure difference value, output current and percentage of measuring range
APLISENS S.A. APLISENS S.A. is a Polish manufacturer of process instrumentation, including pressure transmitters, differential pressure transmitters, level transmitters, and related sensors used broadly across industrial process control. While the company's public product range is general-purpose rather than hydrogen-specific, its pressure and level measurement instrumentation is applicable to gas handling processes, including those found in hydrogen production and storage facilities. APLISENS distributes its products through a sales network spanning many countries, supplying valves, digital indicators, power supplies, separators, and gauges alongside its core transmitter lines.
