1 STXA-D_----EH-87 Solid State Pressure Sensor ANALOG OUTPUT STX Series Model A FEATURES Fastening Mount Calibrated Span and Offset Multi-order Temperature compensation./. or optional or Supply Customized Configuration upon request DESCRIPTION The Series STX Model A is a smart pressure sensor with calibrated and amplified output. The ceramic hybrid package perfor excellent isolation to external stress during operation. Digital compensation of sensor offset, sensitivity, temperature drift and nonlinearity is accomplished in factory via an internal DSP running a correction algorithm with calibration coefficients stored in on-chip EEPROM. A variety of output configuration, including resolution, sampling rate, output interface are available to provide simple and ready-to-use solution for a wide rage of application. The Series STX A is available for pressure range from. psi to psi. Please contact factory for detail.
