AMS6832/36

AMS 6836 small analog low pressure sensor

With a footprint of only 7.6 x 7.2 mm², the AMS 6836 sensors housed in a DIL-6 package are among the smallest differential pressure sensors on a robust ceramic substrate. The tiny pressure sensors are designed for precision pressure measurements in the low and very low pressure range and are available for pressure ranges from 125 Pa to 2000 mbar. AMSYS thus offers a pressure sensor with a precise ratiometric analog output in an extremely small package.

The pressure sensors are extensively calibrated and compensated, featuring extremely small measurement errors at room temperature as well as a very low total error in the compensated temperature range of -25 to 85 °C of only 0.5 to 2 %FS (depending on the pressure range).

Pressure variants and ranges of the AMS 6836

Ultra low pressure differential / relative: 0 .. 250; 0 .. 500, 0 .. 1,000, and 0 .. 1,250 Pa
Ultra low pressure bidirectional differential: ±125; ±250; ±500, ±1,000, and ±1,250 Pa

Low pressure differential / relative: 0 .. 20, 0 .. 35, 0 .. 50, and 0 .. 100 mbar
Low pressure bidirectional differential: ±20, ±35, ±50, and ±100 mbar

Medium pressure differential / relative: 0 .. 200, 0 .. 350, 0 .. 500, 0 .. 1,000, and 0 .. 2,000 mbar
Medium pressure bidirectional differential: ±200, ±350, ±500, and ±1,000 mbar

Absolute pressure: 0 .. 500, 0 .. 1,000, 0 .. 1,500, 0 .. 2,000 mbar

Barometric: 700 .. 1,200 mbar

Compared with the analog/digital AMS 5812—which is ideally suited for medical applications featuring a ceramic cap and stainless-steel pressure ports—the AMS 6836 offers a space-saving alternative with a modern ASIC in a plastic housing.

Note: The AMS 6836 can be custom calibrated regarding the pressure range as well as for lower supply voltages. Special designs, such as different pressure connections, are also available upon request.
