An apparatus delivering water at constant temperature
E R Dymott, J C Evans · Journal of Scientific Instruments · 1951
An equipment is described which maintains the temperature of flowing water constant to within ± 0.01° C. On-off control is employed using a thermistor (or resistance thermometer) and Wheatstone network. Provision is made to attenuate the resulting temperature wave, and an additional thermistor in a compensating network is included to eliminate offset.
