Model AT8051 Gearbox Oil Pressure Sensor
Instruction
Model AT8051 Sensor incorporates Thick-film technology and custom Application Specific Integrated Circuit (ASIC) technology in the design. It is especially suited for harsh environment such as temperature extremes, vibration, thermal and mechanical shock, and corrosive chemical，and mainly used for measuring gearbox oil pressure.
Features
l Static Accuracy: ±1.8％FS
l Thick-film Technology
l Programmable ASIC to Enhance Reliability
l Amplified and Temperature Compensated
l EMI Protection
l Can Adjust the Range and the Output Span Based on the Customers’ Requirements.
