Smart Differential Pressure Transmitter For Low Ranges – Aplisens APRE-2000G Series


  • 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)

The APRE-2000G transmitter is applicable to gases, to the measurements of their pressure, underpressure and differential pressure. Typical applications include the measurement of blast pressure, chimney draughts or pressure / underpressure in furnace chambers. The ability to select the radical conversion characteristics enables the transmitter to be used in gas-flow measurement systems using reducing pipes or other impeding elements. The transmitter can withstand overpressure up to 1 bar. The housing of the electronic circuit has the degree of protection
IP65, IP66 , IP67.
