Dew Point Sensor FA 515 Ex

Introducing our new instrument for dew point or pressure dew point measurement in potentially explosive atmospheres – the FA 515 Ex. This device can be used in numerous non-aggressive gases.

Typical applications include Air/Compressed air, Argon, Nitrogen, Biogas, Natural gas, Hydrogen, and more.

Our dew point sensor, the FA 515 Ex, meets the following industry approval standards:

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 must be used only in conjunction with approved Ex-rated power supplies, safety barriers, or galvanic isolation devices, while ensuring the following maximum values:

Ui = 28 V max.

Ii = 95 mA max.

Pi = 0,65 W max.
