Introduction
Why Field Device Testing is Required For Industries?
Field devices support various protocols and standards for easy adoption and interoperability. A field device OEM should also solicit pre-certification testing to ensure its field devices meet the protocol specifications such that their products can be certified by the concerned standards organization (like OPC Foundation, ODVA, ETG, PI, etc.)

FAQs
1. Does Utthunga provide Pre-Certification Testing?
2. How do field instruments work, and what kind of calibration do they require?
- Transducer calibration which focuses on the transducer input-output output relationship
- Physical end-to-end calibration
- Data system calibration which simulates or models the input of the entire measurement system
All these calibrations ensure that your device measurements are accurate which will positively affect your production process because all the measurements will be correct. This also reduces the variation with respect to the technical specification as well as help in preventive maintenance.
