AO-AD/A Pressure Transducer for Atmospheric / Barometric Pressure

The pressure transducer AO-AD/A registers the atmospheric or barometric pressure in the range of 500...1150 mbar and converts this measured value into a linear output signal 0-10V or 4-20 mA.

As an option the pressure transmitter has a potential-free changeover (changer) contact and a backlit display.

The display content can be rotated in 90° steps using a menu and the actual value, the switching threshold set, the state of the relay, the MIN/MAX measured values for the selected intervals(1 h / 6 h / 12 h / 24 h) etc., can be read out.

On the display version the altitude above sea level can be entered and switched between atmospheric and barometric air pressure.

The atmospheric air pressure is defined by the weather conditions and the altitude above sea level. The barometric air pressure is defined by the weather conditions and normalised according to the altitude above sea level.
If required the pressure transducer can be finely calibrated in situ using an SPAN controller.
