Dew Point Sensor with ATEX approval for explosive areas
The new FA 515 Ex dew point sensors provide reliable, long term stable dew point measurement in industrial, potentially explosive atmospheres or hazardous area. The sensor comes ready to use and simple to install with your choice of 4-20 mA outputs and can be used in many non-aggressive gases.
FA 515 Ex may only be used in connection with approved Ex-rated power supplies or safety barriers or galvanic separating elements with max.:
U2 = 28 V max.
I2 = 93 mA max.
P2 = 0.65 W max.
