Over - and underpressure measuring with one sensor using the example of AMS 5812 Most of the standard differential pressure sensors can only measure pressure differences, whose ratio of the two pressures is predefined. By using bidirectional differential sensors any pressure ratios can be measured. (Article is also valid analogously for pressure sensor series AMS 5105 and AMS 5915.)	aan510.pdf
Precise altimetry (24 bit) with the pressure sensor MS5607 This article describes how the altitude can be measured in a very precise way with a miniaturized pressure sensor on the basis of silicium.	aan509.pdf
Media compatibility of silicon pressure sensors using the example of the AMS 5812 Pressure sensors with silicium measuring cells are sensitive to liquids and a multitude of aggressive substances. The article describes which arrangements can be made to reduce the feared media sensitivity of relative- respectively difference pressure sensors dramatically. (Article is also valid analogously for pressure sensor series AMS 5105 and AMS 5915.)	aan508.pdf
Precision level sensing with low pressure module MS5536-60 Precision level sensing in terms of the modern process automation means more than ”tank is half-full” or “tank is quarter-full“ .The article shows how to measure the precision level as well as inflows and outflows with the aid of the precision pressure sensor. In this manner valuable information regarding the process dynamic can be gained.	aan506.pdf
What to know about differential pressure sensing by means of the AMS 4712 In pressure sensor applications several terms have come into use which describe different physical methods of pressure measurement (e.g. absolute, relative and differential pressure sensing) Especially the term "differential pressure sensing" covers a number of different concepts. Taking piezoresistive sensors as an example the following article attempts to explain the diverse terminology. In particular a frequently needed version shall be outlined: the bidirectional differential pressure sensor".	aan505.pdf
Description how to amplify and calibrate ceramic measurement cells e.g. ME501/505 and ME561. This article describes in detail a simple electronic circuit based on a suitable IC and few external components to amplify and to calibrate the offset- and full span-signal of ceramic sensing elements. The aim is to create a ready-to-mount sensor system with a ratiometric output signal and a suitable level of precision without temperature compensation.	aan504.pdf
Pressure sensors with a 0,5…4,5V output for industrial 3 wires current loop applications. The following article gives an example for a circuit using a pressure transmitter and one single additional IC with very few components, providing an inexpensive solution. We aim to show how a sensor with a standardized current output of 4...20mA can be easily realized as a 3-wire device based on an 0.5...4.5V pressure transmitter in combination with an IC (AM462) from Analog Microelectronics GmbH.	aan503.pdf
