ME800: Ceramic Differential Pressure Sensor for Challenging Media
ME800 ceramic wet-wet pressure sensor ( (C) AMSYS GmbH & Co. KG)
The sensing element consists of a base plate and a flush diaphragm made of 96% alumina ceramic. Due to the high chemical resistance of Al?O?, one side of the sensor requires no additional protective coating. The opposite side can optionally be coated with Parylene, allowing it to be exposed directly to water or other liquid media.
The Wheatstone bridge is applied directly to the ceramic diaphragm. The ME800 provides an analog, unamplified output signal, allowing application-specific external signal conditioning. With a response time of no more than one millisecond, the sensor is also suitable for dynamic pressure measurements. The supply voltage range extends from 2 to 30 VDC, while current consumption is limited to 1.5 mA at 10 V.
Differential Pressure Ranges up to 40 bar
The ME800 is available for pressure ranges from 0 to 4, 10, 16, 25, and 40 bar. Typical accuracy across all versions is ?0.4% of full scale, with a maximum specified accuracy of ?1.0% FS. Depending on the pressure range, the sensor withstands overload pressures from 6 to 80 bar and burst pressures from 8 to 120 bar. The operating temperature range extends from -20 to +105?C.
An optional screen-printed PTC is available. It detects changes in the temperature of the medium and can be used for external compensation of the Wheatstone bridge's temperature behavior. This supports accurate evaluation under changing media temperatures.
Typical applications can be found in medical technology, hydraulics, process and chemical engineering, as well as in the monitoring of pumps, filters, compressors, and closed tanks. Thanks to its compact design, the sensor can be integrated directly into custom housings, valve blocks, and fluidic systems using suitable seals.
AMSYS supports customers in selecting the appropriate pressure range, coating, and external signal conditioning, as well as in the mechanical integration of the ME800 into the respective application.

J+MEMS Series: Piezoresistive Pressure Dies for Low Pressure
AMSYS is expanding its range of piezoresistive pressure dies with the new J+MEMS Series. Measuring just 2.0 x 2.0 x 0.9 mm, these sensor dies enable precise measurement of low and very low pressures. With measuring ranges from 2 to 100 kPa, high sensitivity and compact dimensions, they are particularly well suited for demanding sensor solutions and high-volume applications.
The new J+MEMS Series was developed for measuring absolute and differential pressure…
AMS 4710: Rugged, Miniature Pressure Transmitter
AMSYS offers the AMS 4710, a proven pressure transmitter that shows reliable pressure measurement does not require much space. About the size of a matchbox, the sensor comes ready to connect and provides an analog 0-10 V output. This allows pressure signals to be integrated into suitable measurement and control systems without additional signal conditioning.
Whether in ventilation systems, gas flow measurement or medical equipment, different applications require different pressure types…
Pressure Sensing Die, OEM Sensor or Transmitter? Understanding the Differences
Not all pressure sensors are created equal. There are significant differences between a tiny pressure sensing die and a ready-to-connect pressure transmitter - even though both measure pressure. The key question is how much of the measurement task is already handled by the sensor solution and what the device developer still needs to take care of. AMSYS explains how the different sensor solutions differ in design and functionality.
From the Sensing…
Filter Monitoring with Differential Pressure: Reliably Detecting Contamination
An air filter may look clean from the outside while already restricting airflow. As particles accumulate in the filter medium, the flow resistance increases and, under comparable operating conditions, so does the pressure drop. This difference can be measured with a differential pressure sensor and used for filter monitoring.
Pressure Drop as a Condition Indicator
Pressure is measured upstream and downstream of the filter. The differential pressure Dp is the difference between…
