Setra Model 270 Barometric Sensor

Core Performance & Industrial Application

The Setra Model 270 is a high-accuracy analog barometric pressure transducer using the glass-and-gold-fused SETRACERAM ceramic capacitive sensing element.

The 600-1100 mbar/hPa absolute barometric range covers normal atmospheric pressure measurement for weather and environmental monitoring.

It offers ±0.05% FS baseline accuracy, optional ±0.03% FS high-precision grade, repeatability within 0.01% FS and long-term stability under 0.1% FS/year.

Fast response time under 10 ms and instant warm-up suit dynamic atmospheric and engine test-cell measurement.

It provides 0-5 VDC ratiometric-style output from a 24 VDC (22-32 VDC) excitation with reverse-polarity protection.

It is used as spare replacement in meteorological stations, data buoys and environmental monitoring systems.
