TDK-EPC announced EPCOS MiniCell Series of pressure sensor transmitters, now with an extended range. Said to be the smallest media-separated differential pressure transmitters worldwide, they are available for unsymmetrical measurement ranges from 0 to 500 hPa and 0 to 2500 hPa. In addition, variants are offered for symmetrical measurements from -500 to +500 hPa and -2500 to +2500 hPa. With dimensions of 19.6 x 16.2 x 11 mm³ the differential pressure sensors feature a compact design. Two stainless-steel membranes are incorporated to separate the media. All MiniCell variants have a small oil volume and use a single chip approach for genuine differential pressure measurement. This enables showed high accuracy and reproducibility of the measurements. At a supply voltage of 5 V, the transmitters supply an analog output voltage of between 0.5 and 4.5 V. The maximum measurement error is only 1.5 % FS (full scale) over the entire temperature range.
