1.Product Introduction Standard automotive analog sensor with integrated ASIC signal conditioning circuit. Powered by 5V DC, it converts pressure/temperature physical quantity into linear 0.5-4.5V voltage signal, directly compatible with vehicle ECU and industrial control mainboards. 2.Working Principle Sensitive chip captures physical changes and generates weak raw signals. Internal ASIC completes amplification, temperature compensation and linear calibration, then outputs standardized 0.5V (zero point) ~ 4.5V (full scale) analog voltage signal for controller reading. 3.Common Technical Parameters Pressure range: 0-0.1bar; 0-1bar; Overpressure value: 2bar Burst pressure: 3bar Working voltage: 1:5 +/-0.25V 2:5-18V; Output voltage 0.5V-4.5V Linearity: 0.25% Accuracy: +/-0.04V Pressure mode: Gauge pressure (gage) Operating temperature: -20--65℃ 4.Product Structure MEMS/NTC sensitive chip, ASIC compensation circuit, sealed plastic/metal housing, sealing rubber ring, standard wiring connector 5.Core Functions Standard linear 0.5-4.5V voltage signal output Built-in full temperature range compensation Direct matching with ECU and industrial controllers Real-time continuous physical parameter monitoring 6.Typical Fault Performance Signal stuck at fixed 0.5V or 4.5V Severe signal drift under temperature change Nonlinear voltage output with pressure fluctuation No analog signal output after power supply 7.Application Scope Automotive engine sensors, engineering machinery, new energy equipment, industrial automation detection
