The line of ZOC (Zero, Operate, and Calibrate) miniature Electronic Pressure Scanners incorporates a pressure sensor-per-channel. These sensors are piezoresistive differential sensors. Also included is a high speed multiplexer, amplifier, ID chip, RTD, and auto calibration valving. Full scale output is 0-2.5 Vdc (std) or 0-5 Vdc (optional). These scanners are designed to be used with the users' in-house data systems, ERAD4000 remote A/D, or DSM Digital Service Module.
