Inquire now
  • Our new tool for dew point measurement resp. pressure dew point measurement in potentially explosive atmospheres. The FA 515 Ex can be used in many non-aggressive gases.

  • Typical applications: Air / Compressed air, Argon, Nitrogen, Biogas, Natural gas, Hydrogen, etc.


Dew point sensor FA 515 Ex complies with the following industry approvals:
  • ATEX II 2G Ex ib IIC T4 Gb Zone 1, gas, intrinsically safe, Temp. 135°C

  • ATEX II 2D Ex ib IIIC T80°C Db Zone 21, dust, intrinsically safe, Temp. 80°C

Please note: The FA 515 Ex may only be used in connection with approved Ex-rated power supplies or safety barriers or galvanic separating elements. Thereby the following maximum values must be observed:

  • U2 = 28 V max.

  • I2 = 93 mA max.

  • P2 = 0,65 W max.

Special features of the sensor FA 515 Ex
  • Robust design

  • Pressure resistant up to 500 bar

  • Long-term stable humidity sensor, approved for years

  • 4...20 mA analogue output in 2-wire system

  • Further parameters adjustable via software: % RH, g/m³, mg/m³, ppm, V/V, g/kg

  • NEW: Higher resolution of the sensor signal due to improved evaluation electronics
