IS 2296 covers industrial temperature measurement — selection, installation, and accuracy of thermocouples, RTDs, thermometers, and pyrometers. Type K thermocouple (-200 to 1260°C) and Pt100 RTD (-200 to 850°C) are the most commonly used sensors in Indian industry.
Code of practice for industrial temperature measurement covering thermocouples, resistance temperature detectors (RTD), thermometers, and pyrometers.
Key Values
Type K range-200 to 1260°C
Type J range-40 to 750°C
Pt100 RTD range-200 to 850°C
Practical Notes
! Type K thermocouple is the most widely used in Indian industry — covers most process temperatures.
! Pt100 RTD is preferred for accuracy below 600°C — better stability and accuracy than thermocouples.
! Always use extension wire matching the thermocouple type — mismatch causes measurement errors.
! Calibrate temperature instruments at least annually — drift is a common source of measurement error.
