A Class A Pt100 RTD has a tolerance of ±0.15°C, but signal cable errors can dwarf sensor accuracy. This guide covers thermocouple extension wire selection, RTD three-wire and four-wire cable sizing, single-point shielding philosophy, ground loop diagnosis and elimination using isolated transmitters, and a 4-step noise reduction procedure for industrial temperature measurement loops.
Accurate pH measurement is essential in chemical, water treatment, food, and pharmaceutical processes. This guide covers pH sensor selection criteria, NIST-traceable buffer calibration procedures, electrode aging diagnosis, reference junction maintenance, and systematic fault diagnosis for glass membrane failure, dehydration, and junction plugging using Yokogawa FLXA202 and Honeywell Solu Comp II analyzers.
