Thermocouple readout instrument
Abstract
An electronic circuit was developed which acts as an electronic ice bath for chromel-constant thermocouples. The electronic ice bath was accurate to within plus or minus 0.2 C from 25 C to 50 C. The thermocouple output was scaled and linearized such that the temperature can be read directly in C with a sensitivity of 100 mV/C with OVDC at 0 C. Circuit diagrams and construction considerations were included to allow the reader to construct a functioning unit.
