SAT - System Accuracy Test
System Accuracy Test Methods (As per AMS2750H, CQI-9 & API)
System Accuracy Testing (SAT) is a crucial process used to verify the overall accuracy of a temperature measurement system, including sensors, transmitters, controllers, and readout devices. Unlike individual component calibration, SAT evaluates the entire system as a whole to ensure precise and reliable temperature readings in industrial applications.
Methods of System Accuracy Testing
1. Comparison Method
In this method, the temperature measurement system under test is compared against a highly accurate reference standard in a controlled environment.
Importance of System Accuracy Testing
- Ensures process reliability and product quality
- Detects errors in the entire measurement chain
- Reduces uncertainty in temperature readings
- Improves compliance with industry standards
- Minimizes downtime and maintenance costs
By using these methods, industries can maintain high standards of accuracy in temperature measurement systems, ensuring efficiency, safety, and regulatory compliance.
