PREMASGARD
PREMASGARD ® ALD measures the atmospheric pressure within a range of 850 - 1150 mbar and converts it into a standard signal
of 0 -10 V or 4 ... 20 mA respectively. The sensor system is designed for measurements in clean air and other non-aggressive,
non-condensing gaseous media. Applications of this pressure sensor are for example in ventilation and air conditioning technology,
air pressure dependent control systems, meteorological measurement stations and climate observation units. The pressure sensor
excels by its high accuracy, long-term stability and reliability. A device variant with additional display for pressure reading is available.
