General Function:

For pressure measurement in potentially explosive locations, the pressure transmitter series HDA 3700 is also available in a version for intrinsically safe circuits.
Like the industrial version of the HDA 3700, the ATEX version is also based on a very accurate and robust pressure sensor. With an accuracy level of typically ≤± 0.25% FS and outstanding data in relation to temperature effect, this series of instruments is very well suited to use in potentially explosive atmospheres
