Abstract
A self-contained multiple channel pressure recorder comprises a single, compact, portable housing containing two quartz pressure transducers and electrical circuits for sensing two pressures communicated into the housing to the pressure transducers, for sensing ambient temperature, and for converting the sensed pressures into electrical signals representing absolute pressure magnitudes compensated both for temperature and calibration effects. The resulting data can be locally displayed through a display mounted on the housing, or the data can be remotely transmitted through an electrical coupling mounted on the housing.
