Using transducers in thermometry

摘要

The present article intends to describe temperature measurement circuits by employing various temperature transducers. The circuits are based on NTC thermistor, BC177, LM35 & AD590 transducer, applicable for temperature measurement in solutions. Each design includes a temperature transducers, voltage offset network and opamp based amplifier. The linearity check, calibration procedure and a sample thermochemical experiment are also given. These transducer-based thermometers are amenable to self-design, easy to maintain, cost effective and are capable of doing well in chemical laboratories.
