Media resistant differential pressure sensor ME800
The medium comes into contact with a Parylene coating on one side and with the Al2O3 of the membrane with excellent chemical resistance on the other side. Using o-rings the sensor can be easily integrated into valve blocks or similar housings. Thus for differential pressure measurements only one differential pressure sensor is needed instead of two relative sensors. Therefore only one single error has to be considered, which improves the overall accuracy of the system and makes the sensor special.
A more sophisticated variant is the ceramic differential pressure sensor ME821 with integrated signal conditioning. This version provides a calibrated output signal of 4 - 20 mA for current loop inputs. The ME821 offers a wide supply voltage range from 9 V to 35 V and can be operated in a temperature range from -25 C to +85 C.
Because of its high chemical compatibility, the ceramic sensor ME800 is the preferred choice for applications in medical technology as well as chemical or gas/oil industry. However, this ceramic sensor is also suitable for hydraulics, compressor control or level measurement in closed tanks due to its accuracy and wide temperature range. AMSYS also provides the pressure sensor ME800 with an optional additional PTC for temperature measurement, ideal for external temperature compensation.

AMSYS GmbH located in Mainz, Germany offers a full line of innovative pressure sensors. The portfolio extends from pressure measurement cells made from silicon and ceramic, compensated OEM sensors up to packaged, ready-to-use pressure transmitters with analog and/or digital outputs. The product spectrum ranges from ultra-low 125 Pa pressure sensors (1.25 mbar) to high-pressure sensors of 800 bar including all types of pressure (absolute, gauge and differential pressure).
Particular emphasis is on media-resistant OEM pressure sensors and transmitters with novelties in the field of wireless sensor solutions.
Besides from pressure sensors and multi-functional sensors (pressure, humidity and/or temperature), AMSYS also offers calibrated humidity, temperature and inclination sensors. In addition to detailed product descriptions, the AMSYS homepage (www.amsys-sensor.com) offers numerous development modules and many illustrated application examples.
