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. Areas
of application for this pressure sensor include ventilation and air conditioning technology, air-pressure-dependent control systems, meteorological
measurement stations and climate observation units. The pressure sensor excels thanks to its high accuracy, long-term stability and reliability. A
variant with an additional display for pressure reading is available.
