Abstract A single time-constant approximation of the lag of temperature-measuring systems is often adequate for evaluating the effect of the system lag on the control loop and for indicating the fidelity with which transients are recorded. The value of this approximate time constant is dependent upon the system and on the properties of the fluid whose temperature is being controlled. This paper suggests a method of presenting information on systems from which the user can determine the single time-constant approximation for his operating conditions. Experimental procedures for obtaining the necessary information are discussed.
