With the Epcos MiniCell series, TDK-EPC launches what the company claims to be the smallest pressure sensor transmitters worldwide, 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.
Measuring only 19.6x16.2x11mm, the differential pressure sensors feature two stainless-steel membranes that separate the media. All MiniCell variants have a small oil volume and use a single chip approach for genuine differential pressure measurement.
This enables high accuracy and reproducibility of the measurements. The stainless steel membranes and supports also make them suited for use in aggressive media. The electronics of the MiniCell transmitter are hermetically sealed in inert oil inside the ceramic package.
The transmitters are designed for a broad temperature range from -40 to +140°C. At a supply voltage of 5 V, the transmitters supply an analog output voltage of between 0.5 and 4.5V. The maximum measurement error is only 1.5 % full scale over the entire temperature range.
Applications of the MiniCell transmitter include process engineering, the chemical, food and water industries as well as aviation measurement systems. In addition to standard versions, customer-specific housings are also available for standalone applications.
