MB3 B

The core of the sensor is an aneroid capsule coupled with a magnet & coil transducer (similar to the one used on short period seismic sensor ZM500). A secondary coil wrapped around the main one ensures remote calibration capability. Two versions are proposed. One analog (MB3a) compatible with usual digitizers. The second one is digital (MB3d) embedding a very low consumption high performance ADC.
