Pressure measuring transducer for atmo­spheric pressure


The PREMASGARD® ALD measures the atmospheric pressure in the 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 suitable for measurements in clean air and 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 is characterised by its high level of accuracy, long-term stability and reliability. A variant with an additional display for pressure reading is available.

Pressure: 850-1150mbar / 750-1250mbar
Output: 0-10V or 4...20mA
